And is this a trick question? Hmmmmmm...
I can't believe not a single one of you brought up that speed is relative.
Also e=mc2 is not correct when an object has momentum.
if someone travels 3/4 the speed of light in one direction, and someone else travels 3/4 the speed of light in the other direction, relative to each other, is one traveling faster than the speed of light?
i cant remember the answer lol but i know ive seen it somewhere before.
and also i believe conventional science tells us no, but there is theory about shrinking the space infront lol but that could have been discovery blowing smoke out its dog lol
Well in conventional physics, if im driving a car down a highway at 50, and someone else is coming the other way at 50, the speed relative to eachother is 100. so what happends if you crank those speeds up to a point where you get a number faster than the speed of light?
Yeah apparently nasa is working on creating a warp drive that could essential fold space time in front and behind them to propel them faster than speed of light. I don't think it necessarily would be going faster than speed of light though. nuggets so confusing to me.
And the first part to your post is so confusing. Makes no sense to me. I'd be even more confused if the answer was yes one would be going fast than speed of light.
relative to what? distance/time? or that light travels at different speeds in another vizion of the universe?
Speed itself is relative. Like right now I'm going 0 mph relative to the Earth, but say 30,000 mph relative to the Sun. Without a reference point, you can't have speed.
So you could say you're going 30 trillion miles per second right now.

I just wanna know if there's any weird alterations to the way physics function if you were to blast off towards the center of the universe, in essence slowing down. Just would be interesting if matter reacts differently if it isn't moving.
Especially if it was also cooled to absolute zero.
I thought absolute zero is impossible to recreate on earth because the object your freezing always has to touch something, which creates heat. But it occurs in space, or something...
That we've seen. That doesn't really mean it can't happen. After all we haven't found the end of it yet. Which would be the coldest. And we never will.
Is that it Pi? It's not loading on my phone... :(
Who's it about? It's not that I don't believe raven, it's just I learned it from bill, I can't ever recall talking about absolute zero in school. So I wanted to know what he said about it at the time.

This is actually how space travel works in Star Trek. As I've stated, you can't move any object at the speed of light, but that doesn't mean space can't. So if you bend space you create a warp bubble around an object where space is moving faster than light, but your object is essentially stationary.
On another note, I seem to recall Light being at C in a vacuum regardless of relativity.
There is no center of the universe :O
In order to achieve an actual absolute zero state it would either require the entire universe to stop moving even at the quantum level (clearly not desirable) or create a type of pocket universe that is untouched by our own until it is willed to be interacted with but that may also make it impossible to actually measure its temperature since the moment you observe it the pocket would become affected and thus heat back up. So it would still only be a theoretical temperature. It would require quite abstract and frankly unheard of means to be able to exist and be observed without being affected.
Space works differently, in that it should be 0K. The universe doesn't move in the same way objects do, it just expands. The only reason why it's not at 0K is because there's still the radiation from the big bang. This temperature is also decreasing and is around 3K right as we speak.
We should have a sicence thread.
We should have a sicence thread.
Question: So if time basically stops when you are traveling at the speed of light, would that essentially mean that if you went back to earth after say 20 days of space travel for you would time on earth be farther ahead in time than you would think? So that 20 days to you was say 6 months on earth? THIS STUFF HURTS MY BRAIN!!
Yes, most likely.
Time dilation is weird.
I personally don't believe it's understood enough to definitively state things like that.
Say we have two objects in deep space. The difference in speed between the two is .9 the speed of light, or just really really fast.
Which object is the one experiencing time dilation, and which is the object no experiencing it?
Well isn't time dilation something that supposedly happens to all objects once in deep space? So wouldn't both be experiencing it, but just one would experience it more than the other?
There is an area in space at 1k. What I'm saying is that right now, barring what appears to be inevitable for everything in the universe, absolute zero is impossible. There is no area in space this has happened and is not within our means to achieve. If absolute zero were achieved now naturally or artificially the scientific community would probably slam on the panic button. Absolute zero will always be a theoretical temperature because measuring something causes it to be affected and if everything in the universe hit absolute zero there would be no way to measure anything.
That's the thing, it will take god knows how many years, but once the background radiation in the universe dissipates, it will become 0K.
The curvature of spacetime has something to do with time dilation imo.
That'd give objects a clear reference point that isn't relative.
I need to read up more on space-time and time dilation. Cause I'm over her like DAFUQ???!?!?!?!? LULZ
is anything in the universe not in motion? the planet earth is moving, so by association everything on it is as well constantly. Does the sun move or rotate? Black holes?
Not in motion relative to what?
are there no absolutes in the universe? I mean just like the idea of "absolute zero" is there such a thing as "absolute inertia"
If I have two rocks and throw one and not the other, that doesn't mean that the one not thrown is moving because I threw the other rock.
Motion as defined as movement, or moving, having force applied to it where it changes its physical space of occupancy in some way shape or form. Not necessarily relative to anything. However, such as instances on our planet where there is a base motion occurring to all things equally all the time I would say that counts as motion.
So can something perhaps in space be stabilized in and of its own with out being affected by external forces (or it being counteracted mechanically some how) to where its not moving period?
There's absolutes, but absolute speed is not one of them.
If you were in a spaceship with no windows, you wouldn't be able to calculate speed. You can calculate and feel accelerations and therefore determine changes in speed, but that's it.
What? Who doesn't put a speedometer in a space ship? :P
You're talking about the "Big Freeze", right?

hmm interesting thought about absolute speed though... I mean there are constants, like gravity and the speed of light, but I wouldn't call those "absolute speeds" either. If there is an absolute '0' is there an absolute max heat value? So I suppose I could pose the same question as per absolute inertia, could there also be an absolute speed? Time is a constant I'd say, but it does seem to be mostly relative in how we track time, but a moment passes regardless of how different the measures could be made to distinguish by how much it has passed.
To define an absolute speed we would need absolute parameters for measure in terms of time and distance. Temperature seems simpler in terms as it is merely a measure of a singular factor.
Again I pose the question, but in different terms: Is it possible for an object to exist with absolutely no external force being applied to it? Absolute inertia or 0 speed?
No, I'm just remembering what my Astrophysics teacher taught us so I'm not sure what this "Big Freeze" is. Space is supposed to be at 0K since it expands, it doesn't move. But it's near 3K. Which led scientists to believe that the 3K background radiation is the remnants from the Big Bang when it was still a singularity of infinite energy. Though I was thinking about more and I'm unsure if that radiation will dissipate or not and the 3K might be a result of the universe thinning it out as it expands. Thus it thinned out to 3K and should settle to an near 0 level but not at it. Not sure what would be true, I'd have to ask a physicist on what would happen to the radiation.

From what I understand space will approach absolute zero but never truly achieve it nor will absolute zero be possible so long as it can be observed. Observing something influences it at the quantum level which makes it impossible to measure an absolute zero state. Space is not empty. It has quantum makeup just like anything else. The only way absolute zero is truly possible is for everything in the universe to be in that state so that no observations can be made and thus no quantum excitements can occur.
This is assuming that things at the quantum level can also be put to a halt which, from our current understanding, they actually cannot. Things that happen on a macro scale often mean jack to things on the quantum scale but things on the quantum scale can quite easily influence those on a macro scale. As long as something is happening at those tiny scales absolute zero cannot truly be achieved which means it never will be, based on our current understanding, since things at the quantum level often do as they dang well please regardless of what even common sense would tell you.
The Big Freeze is the growing scientific consensus on the ultimate fate of a lone universe in which the expanding distances of matter, lack of gas to form new stars, and increasing number of black holes eventually lead to an entire universe at near absolute zero which is incapable of sustaining life as we know it. A state of maximum entropy is then reached where information can no longer be processed. Basically, everything becomes freezing fudgy cold to the point where everything dies and then eventually nothing can happen at all. The good news is that quantum activity will still likely, at some point, give rise to a type of big bang which would start a whole new process.
Space is empty, so to speak. Which is why it should be at 0K. Obviously right now that's not the cause because of the radiation. Like I said, it depends what happens to this radiation. If it dissipates completely then the universe will become 0K with whatever sun, planet, etc, inbetween giving off energy and moving.
I recall the universe burning out of hydrogen in the trillions of years. Its one possibility. The other is a contraction. It depends what the cosmological constant ends up being. There was a third option I can't remember right now. I really wish I knew where my astrophysics book went :/.
I believe in the contraction theory. Basically, the universe exploded and we are still experiencing that effect. Over time it will stop expanding and start contracting on its self, and then explode again, starting the whole cycle over.
Apparently, as of today, scientists have less support for the idea because more of them believe that gravity is not slowing the expansion of the universe down like they previously thought. Rather, the expansion is accelerating from certain observations. There are some other factors that need to be considered though. What will ultimately happen to the universe is far from decided and most theories revolve around this being the only universe. There are some others that say this is not the case.

There is still much force behind the expansion. We wont be around when the universe slows down. Where are you reading this? Because i was watching a "through the worm hole" just a few months ago or maybe weeks that talked about that. Maybe that episode was dated but couldn't be that old. Is the scientific community changing it's mind that quickly? Then again, that's all they talked about during that episode and didn't talk about the others.

There was one episode of AE where they kept finding examples in the bible and art of the Earth being round instead of flat.
"The people back then thought it was flat, so aliens must have told them the truth!"
The truth actually is that the Earth being round was common knowledge for thousands of years.

why wouldn't they be able to go faster?
Well for starters the speed of light is constant regardless of how fast you're moving.
If you're going 10 trillion mph and turn on your headlights, they'd still work just fine. It's all very complicated and confusing.
yeah but why?

so if i'm driving 30mph and I turn on my lights, the light isn't going 30mph+ speed of light? does that mean if you were going close to the speed of light the distance light went would be shorter than if you were going slower?

What if going backwards in time was just going forwards in time, but in reverse?
That makes the kind of sense that feels like an epiphany, but then you try thinking about it more and end up going "meh".
Nah the more you think about it, the cooler it gets.
Imagine a universe that was going backwards in time. Physically, it'd be perfectly fine. It'd just have the complete opposite rules as us.

Savants are interesting.Spoiler for Hidden:
What are savants?
Kim was able to memorize things from the age of 16-20 months. He read books, memorized them, and then placed them upside down on the shelf to show that he had finished reading them, a practice he maintained all his life. He could speed through a book in about an hour and remember almost everything he had read, memorizing vast amounts of information in subjects ranging from history and literature, geography and numbers to sports, music and dates. Peek read by scanning the left page with his left eye, then the right page with his right eye. According to an article in The Times newspaper, he could accurately recall the contents of at least 12,000 books.[6] Peek lived in Murray, Utah and spent a considerable amount of his time reading at the Salt Lake City Library and demonstrating his capabilities at schools, with great help from his father.[10]
Peek did not walk until he was four years old, and then in a sidelong manner.[8] He could not button up his shirt and had difficulty with other ordinary motor skills, presumably due to his damaged cerebellum, which normally coordinates motor activities. In psychological testing, Peek scored below average (87) on general IQ tests.[11]

thats if time its self is has a linear model as we perceive it.
Well it doesn't matter how time actually works, since it'd just be us percieving it as backwards.
but can it run "backwords"? lets say it does, would you see everything in reverse?
Generally, they are people who have very poor intelligence, but are exceptional at something.
Like one guy is unable to multiply 3 x 5, yet he could tell you that February 7, 1900 fell on a Wednesday in a few seconds. Or that December 8th, 2098 will fall on a Monday.
Well, not necessarily poor intelligence. But I think those are the coolest cases. If you've ever seen Rain Man.
This is about Kim Peek, who Rain Man was based off.

You can't put anything in a black hole. They're singularities of matter.
Yeah but that part of Interstellar was pretty much fiction anyways. I can't wait to learn more complicated science at college :)
Once you learn it, then build a spaceship and go see it!
Black holes do involve time, but the film was a complete scientific fiasco.
I'm impressed that you actually made sure those weekdays were accurate :)
Yeah it's interesting that lots of above average intelligence people have other parts of their brains severely below average.
Much much better than gravity though!
I'm impressed that you actually checked to make sure those weekdays were accurate.
That's not saying much, tbh.
I just got a laugh when they landed on the one super speed high gravity planet. They should have been pasted instead of being able to walk around.
Spoiler for Hidden:
so i got a question, what would happen if two planets nearly collide? i mean just miss each other.
Spoiler for Hidden:
BK edit: just covering up spoilers, yo.
There is almost certainly a distance at which the effects would be catastrophic, at least on the surface, while still missing each other. I would imagine a ton of electromagnetic disturbances, tremendous winds, very high temperatures, raging storms, possible tectonic upheaval, in addition to some atmospheric and gravitational effects I can't even imagine. Then again I could be completely wrong and we'd just pass by while waving at each other. Put it this way, if the moon's gravity effects us you can probably imagine two equally sized planets with substantial gravity zipping by each other at high speed within relative "inches" wouldn't be fun.
Well considering what the moon does to the oceans...
Or what I do to you in bed. Wait what?
You cheating on me?
It was a secret only to you. I'm the village bicycle.
Can't watch the video atm but going off the title
no?...
Oh hey it's exactly what I've been telling people about everyone knowing the Earth was round! Hahaha.
Also with the gravity thing, was he ignoring Earth's rotation? I mean squishing the planet like that would greatly increase the radius so innertia would really help keep gravity feeling down.
Here's a new subject of discussion.
1. A rocket shoots off from Earth. It accelerates almost instantaneously to 99% of the speed of light, relative to Earth. This rocket then does a grand tour of the Milky Way galaxy. After going in a large circle, it slows down and lands back on the Earth. Earth clocks will have shown thousands of years have passed, while clocks in the rocket will only show a few minutes have passed. Correct?
2. If so, then the same is repeated except with space ship A and space ship B. Both are in orbit around our solar system, but far off beyond Pluto. Space ship A never turns on its engines, while space ship B shoots off on a grand tour of the galaxy, just like the rocket before. Relative to space ship A, space ship B is going 99% the speed of light. When space ship B returns, its clocks show only a few minutes have passed, while space ship A's clocks show thousands of years have passed. Correct?
3. If so, then the same is repeated expect out in deep deep space, far away from any galaxies. Space ship A and space ship B are out in the middle of nowhere with the same relative velocities. Then space ship B turns on its engines and shoots off for a similar journey as before, just in empty space. When space ship B returns, its clocks show only a few minutes have passed, while space ship A's clocks show thousands of years have passed. Correct?
4. If so, then the exact same thing is repeated with two new ships. However both of these ships have no windows and no way to see the outside world, except for the other space ship. When this happens, both ships perceive the other ship is the one flying off at 99% the speed of light. When the ships meet up again, they would both think the other ship had perceived a shorter amount of time. Correct?
See if you can try and spot the flaw in this line of thinking.

What if consciousness is everywhere? No different than magnetism.
Then our brains simply align all the microscopic consciousnesses and magnify the result, again just like magnetism.
I kinda have one question that I'm going to ask 3 different ways.
Do you think personality just a description of an intelligence or is it, it's own part?
Another way of asking, is personality completely learned or is there something inherent that's separate from the majority of intelligence?
The last way of asking, is if you were to design the perfect AI, would there be a need to program a personality or would the personality be a byproduct of the rational system?
Does this question make sense?
Hmm.
I was writing something but I didn't like where it was going.
Short answer: I think both personality and sentience are a byproduct of experiencing things and having the power to alter experiences. You are born with neither, but the physical makeup of your brain can have large impacts on them.
Now I'm curious to know where it was going.
My AI textbook that I got, seems to focus more on making rational decisions, which isn't necessarily what I want all the time.
Follow me on this one.
Imagine a system that takes an input and produces an output. It's basically a function, a converter. Let's call him Steve.
Steve is simple. He has a camera, a speaker, and an arbitrary amount/setup of logic flowing from the first to the second. He lives in a room watching a tv. No matter how complex that converter/brain ever gets, it cannot make Steve sentient or have "thought." The same image on the TV produces the same possible outcomes.
In order to be more than that, some sort of feedback loop needs to be introduced. Let's replace Steve's speaker with a light. Now Steve's output affects the brightness of the room. This in turn is picked up as input for his camera. Now when we put the same images on the TV, Steve is not necessarily seeing the exact same thing before and thus could have a different output. Although extremely limited, thought is now possible. The loop introduces memory as well.
So I believe consciousness, sentience, and personality are all fundamentally the results of these loops.
What are they?
Why's that? :o
He's a string theorist, while Tyson thinks it's hogwash ;)
But more seriously, Tyson's "Cosmos" TV show has/had some pretty annoying elements about it beyond the science. Their drawings were just weird and at least to me some elements came across as anti-church.
But even more seriously, Tyson is worried about AI!
Math, but should there be a math thread? :o
"If two space ships are traveling towards eachother at 60% of the speed of light, what is their relative velocity?"
Do you mean from Earth's perspective they are traveling towards each other at 60% the speed of light? Then from their perspective the other would be going like 85% the speed of light.
EDT:
88.2% the speed of light.

Philae lander delivers 'ground truth' by touching and analysing material on a comet's surface - ITV News (http://www.itv.com/news/2015-07-30/philae-lander-delivers-ground-truth-by-touching-and-analysing-material-on-a-comets-surface/)We came from comets! Confirmed
Math!Good ol' Discrete Math. I mean... fudge Discrete Math. dang "proofs"
Suppose the set n
{1,2,3,4,5,6,....
Now double every number in the set.
{2,4,6,8,10,12,....
According to that, n and 2n have the same length. Because every number in n corresponds to exactly 1 number in 2n and vice versa.
But every number in 2n occurs in n, and n also includes lots of other numbers, 2n-1 and 2n. So by that logic the first set should have twice as many numbers.
{1,2,3,4,5,6,7,.....
Now square every number
{1,4,9,16,25,36,49,....
Same deal, except way bigger difference.

Did Stephen Hawking Just Solve Black Holes' Information Paradox? | Nerdist (http://nerdist.com/did-stephen-hawking-just-solve-black-holes-information-paradox/)I doubt the holographic principle, much less string theory as a whole, is correct.
Holograms! Why didn't anyone think of this sooner?
I doubt the holographic principle, much less string theory as a whole, is correct.String theory is hard to prove since we live in 4 dimensions... I personally think subatomic particles existing in greater dimensions is correct.
It's been around far too long without gaining any experimental evidence to back it up. The standard model only took 12 years to get confirmed. String theory is approaching 50 years of nothing but math.
String theory is hard to prove since we live in 4 dimensions... I personally think subatomic particles existing in greater dimensions is correct.Well if the holographic theory is correct, we'd live in 2 dimensions ;D
Well if the holographic theory is correct, we'd live in 2 dimensions ;DNah, imagine this 3 dimensional fly getting smushed by my hand/gravity against this sheet of paper getting pressed into a 2D fly.
Well if the holographic theory is correct, we'd live in 2 dimensions ;DNot sure about the holographic theory :P. Though I recall learning in my grade 12 Physics class that we don't quite understand how holograms work. You can take one, cut it in half, and it'd retain the full image. Like, we know how to make them, we don't know how they work.
Nah, imagine this 3 dimensional fly getting smushed by my hand/gravity against this sheet of paper getting pressed into a 2D fly.Haha that's an ELI5 answer if I've ever seen one.
Or something...
Not sure about the holographic theory :P. Though I recall learning in my grade 12 Physics class that we don't quite understand how holograms work. You can take one, cut it in half, and it'd retain the full image. Like, we know how to make them, we don't know how they work.The holographic principle is named after laser holograms but it's not really based off the physics behind them.
Haha that's an ELI5 answer if I've ever seen one.I know. I was just saying, or rather my teacher, that holograms contain all information at every part of the hologram. Which is why the full image will be on two halves. You can even quarter it, all quarters will retain all information.
The holographic principle is named after laser holograms but it's not really based off the physics behind them.
Traditional holograms are really well understood. They're just the interference pattern between a coherent light source/laser after being split and having one half bounced off an object. Shining an identical light back through the interference pattern simple recreates the other beam. In the modern computer age, these interference patterns can be calculated for 3D models and directly printed on glass.
The "cut in half" phrase is often stated but I've always found it misleading. It still destroys half of the interference pattern and half of the information about the object. A better analogy is that holograms are like windows. If you cut the window in half you can still see the entire scene through it, but your view is now restricted to a smaller area. So for example if you have a hologram of a 2d object right up against the glass, it acts exactly like a traditional picture. Cut it in half and half of the 2D object is gone forever.
I know. I was just saying, or rather my teacher, that holograms contain all information at every part of the hologram. Which is why the full image will be on two halves. You can even quarter it, all quarters will retain all information.I'm saying that's wrong.
I'm saying that's wrong.Probably. That was a long time ago.
Probably. That was a long time ago.Haha yeah holography is one of my hobbies. Hoping to buy a VizionEck hologram after it releases.

i love itQuoteFor five years, the astronomers from Bochum have been monitoring our Galaxy in the search of objects with variable brightness. Those objects may, for example, include stars in front of which a planet is passing, or multiple systems where stars orbit each other and which obscure each other every now and then. For his PhD thesis, Moritz Hackstein is compiling a catalogue of such variable objects of medium brightness. It uses data from a team led by the University's Chair of Astrophysics that takes pictures of the southern sky night after night. They use the telescopes at Bochum's university observatory in the Atacama Desert in Chile. More than 50,000 new variable objects, which had hitherto not been recorded in databanks, have been discovered by the researchers so far.Scaled Image Interactive Image (Currently it's a little bit slow)http://gds.astro.rub.de/ How they made it
QuoteThe area that the astronomers observe is so large that they have to subdivide it into 268 sections. They photograph each section in intervals of several days. By comparing the images, they are able to identify the variable objects. The team has assembled the individual images of the 268 sections into one comprehensive image. Following a calculation period of several weeks, they created a 194 Gigabyte file, into which images taken with different filters have been entered.

Wow I can't believe I didn't realize this earlier.I feel like I'm learning lots of things.
As a kid I learned of the big bang as an explosion like a supernova. Pretty sure every layman thinks of it like that, yet I kept this understanding even after learning about cosmic background radiation, higher dimensions, expansion, etc. Wasn't till an hour ago that something caused me to think about it and realise what we learn as kids is wrong.
The universe was always infinite in size and practically infinite in energy at every single area. The big bang was more like a big stretch, where the infinite universe expanded and decreased density. No explosion :(I'm not quite so sure about the bolded, but the rest of it is quite correct.
Now for my personal line of probably incredibly flawed thought, I wonder if the universe has cycles like stars. The initial state of the big bang sounds a heck of a lot like the eventual heat death of the universe, just with a different density value. It seems reasonable that before the big bang a super high energy low entropy state could have existed that slowly evened out, and a super low energy high entropy state could form after the heat death, with new physics emerging at every transition. All our forces were originally combined during the first moments. IDK, it's always fun thinking about this stuff before bed.This is something that I've heard at least considered. A TV show actually made some idea similar to this. And I've heard about similar ideas in other places too.
I'm not quite so sure about the bolded, but the rest of it is quite correct.The universe might loop, but you can travel in every direction an infinite distance (excluding black holes). That's all I meant.
This is something that I've heard at least considered. A TV show actually made some idea similar to this. And I've heard about similar ideas in other places too.I've read up on the Big Crunch and Big Rip, I just never made the connection that my childhood understanding of it starting with an explosion was wrong.
Well in Futurama what happened is that after the universe dies, there is another big bang. One of the guys who worked on Futurama actually has a Physics degree from Harvard. So while the show certainly takes unrealistic liberties, someone there actually has some experience to draw from.
There are these ideas about the end of the universe like Big Crunch, Big Rip that might be interesting to you, if you haven't heard of them.
I'm sure Xev will be able to tell us lot's of stuff once he's done. ;)

Why does it take 3 years to develop a new car, when it shares 90% of its "DNA" with the previous model? Why does it take 6 years to develop a new airplane when it shares 90% of its "DNA" with the previous model?How did we lose the technology to go to the Moon? - Quora (https://www.quora.com/How-did-we-lose-the-technology-to-go-to-the-Moon)
The answer is that they are complex devices. A launch vehicle and spacecraft destined to go to the moon is much more complex and operates at the edge of the envelope where there is little tolerance for imprecision and error.
When operating on the edge of the envelope, thousands and thousands of hours go into testing and tweaking. The development and operations teams acquire expertise that no one else on the planet has. The vehicle cannot be built or operated without that expertise.
Operating a space mission involves reams of paper in the forms of flight rules and operational procedures. Those rules and procedures are drafted over thousands of hours of test and simulations. A change in the vehicle can send ripples of changes through those documents.
The Saturn V rocket had over 3 million parts. The command and service modules and lunar module were composed of millions of additional parts. An individual person cannot contemplate the scale of detail needed to assemble and operate those vehicles.
So, when the Apollo program ended, the factories that assembled those vehicles were retasked or shut down. The jigs were disassembled. The molds were destroyed. The technicians, engineers, scientists, and flight controllers moved onto other jobs. Over time, some of the materials used became obsolete.
If we, today, said - "Let us build another Saturn V rocket and Apollo CSM/LEM and go to the moon!" it would not be a simple task of pulling out the blueprints and bending and cutting metal.
We don't have the factories or tools. We don't have the materials. We don't have the expertise to understand how the real vehicle differed from the drawings. We don't have the expertise to operate the vehicle.
We would have to substitute modern materials. That changes the vehicle. It changes the mass, it changes the stresses and strains, it changes the interactions. It changes the possible malfunctions. It changes the capabilities of the vehicle.
We would have to spend a few years re-developing the expertise. We would have to conduct new tests and simulations. We would have to draft new flight rules and procedures. We would have to certify new flight controllers and crew.
We would essentially be building a new vehicle.
And that's what we are doing. As similar as Orion looks to an Apollo Command Module, as much as we think we understand heat shields and parachute deploy systems - we have to understand these specific heat shields and parachute deploy systems. NASA has people doing these tests, every day.

Then a player adds things into an environment.
You're watching Simpsons, what if you add a character. Maybe a random one to the show. Maybe you add a pre-made one, or make your own. Suddenly some character from South Park or Family Guy is in the Simpsons story.
Think it'd be interesting.
Great for kids, but I'd hate it as an adult.

In similar news, North Korea tested a hydrogen bomb the other day.Ive been reading about this. A few people are suggesting that it's propaganda.
The size of the explosion, yielding a 5.1 magnitude earthquake, is roughly what you would get from a 10 kiloton bomb, half of the energy release of the first US pure fission bomb exploded in New Mexico. So they are still producing duds. The first three US fission bombs were not boosted, and they released considerably more energy than did this North Korean test.
Nonetheless, I suspect that the engineers and physicists responsible for this bomb told Kim Jong Un that they had successfully exploded a hydrogen bomb. It was their quickest way to be able to claim "hydrogen" -- by assembling a boosted fission bomb.
Moreover, I suspect the bomb was even smaller than 10 kilotons. It is in the North Korean interest to try to exaggerate the size of the blast. If I were given the job of doing that, I would do it by increasing the coupling between the explosion and the rock. (If you are trying to hide a bomb, you decrease that coupling.) The goal would be to transfer more energy to the rock, thereby fooling the seismic people into thinking that a bigger bomb was exploded. Increasing that coupling is technically far far easier than making a bigger bomb, so I assume that's what they did. That means that their "hydrogen bomb" might have been only a few kilotons, maybe 1/10 the size of the first WWII US weapons.
In similar news, North Korea tested a hydrogen bomb the other day.I think it was more of an atom bomb with hydrogen inside.
In similar news, North Korea tested a hydrogen bomb the other day.Chinese News posted how to build Hydrogen bomb.
From the research I've seen, boys and girls tend to be about the same (or girls slightly better) at math until puberty. It is then that boys start pulling ahead, on average.
This actually makes pretty good sense. At puberty, boys get their testosterone levels up. This makes them stronger, more aggressive, and more focused (in order to fight off aggressors). On the other hand, at puberty, girls bodies and brains turn into baby-making machines.
This makes perfect sense from an evolutionary point of view. Most people who lived to adulthood didn't live very long - around age 40 or so. So women would have spent most of their adult lives having and raising children. To do so successfully, they would have to develop better social skills than men.
Primitive men would need to be patient and single-minded when it comes to hunting or protecting.
So now let's think about Einstein. From 1905 to 1915, he spent most of his time thinking about the General Theory of Relativity. It's a wonderful theory, but how many women do you know that would spend 10 years focused on such an abstract topic?
Women, on average, are more social beings. This has a tremendously beneficial influence on our culture. Biologically, there would be less desire to become a mathematician or theoretical physicist. More women today are becoming doctors, and there's some pretty good evidence that they are better doctors than men, because they listen better.
My wife, daughter and sister all are extremely intelligent. But none of them will stay up all night, as I sometimes do, to solve a math problem, or write a computer program.
I'm sure there are cultural forces at play here. And there probably always will be.
Yet, there are many women who do make great mathematicians. And our society should encourage all children to pursue their passions.
We have some excellent programs at UT Dallas, that are aimed at assisting women to feeling welcome in our Computer Science Department. I strongly commend these efforts.
Those who think that 'true equality' would mean that we should get to the point where every field has 50/50 men and women are not for equality; they are for quotas.
Only women can give birth to another human - and that mother has more influence on the future of that child than anyone else in the world. If we tried to downplay this, as our culture has done, it will be to the detriment of all.
So now let's think about Einstein. From 1905 to 1915, he spent most of his time thinking about the General Theory of Relativity. It's a wonderful theory, but how many women do you know that would spend 10 years focused on such an abstract topic?I can think of zero woman, but I can also only think of 1 man. Such a weird point.
Eh, that kind of seems a bit offLol, it's true.
I can think of zero woman, but I can also only think of 1 man. Such a weird point.

Century From 1890 To 1989 (http://arxiv.org/abs/1601.03256)
" The star KIC 8462852 is a completely-ordinary F3 main sequence star, except that the light curve from the Kepler spacecraft shows episodes of unique and inexplicable day-long dips with up to 20% dimming. Here, I provide a light curve of 1232 Johnson B-band magnitudes from 1890 to 1989 taken from archival photographic plates at Harvard. KIC 8462852 displays a highly significant and highly confident secular dimming at an average rate of 0.165+-0.013 magnitudes per century. From the early 1890s to the late 1980s, KIC 8462852 has faded by 0.193+-0.030 mag. This century-long dimming is completely unprecedented for any F-type main sequence star."

This is so exciting!Well they already kinda knew how to do it, but there was always the worry some prediction or calculation was wrong. Now that it's confirmed to be useful science, investing in more interferometers isn't as risky.
It's amazing that they've finally found them, I can't wait to see what else they'll discover now they know how to do it!
I am hoping the successful detection of gravitational waves will open the door for the discovery of unexpected phenomena, particularly in the Milky Way galaxy, possibly in the nature of strong gravity.
It is wonderful that their first detection came so soon after they turned the detectors on; that suggests that there will be many detections per year. In addition, the nature of the discovery-- a rapidly oscillating signal that decayed quickly -- is exciting. It's obvious interpretation, that of a black hole and star falling into each other, is very interesting. It is,perhaps, the most interesting of the expected phenomena, and if it is common, then it is even more interesting. It is not yet clear what will will learn from the observation, particularly if it just verifies what we expected, but it is likely that there will be something unexpected too.
I emphases again, as I did in previous postings to Quora, that this is not the first proof that gravity waves exist, nor is there anything yet that verifies something in general relativity that was previously unverified. The Taylor-Hulse binary pulsar, back in the 1970s, accomplished that. Indeed, the discovery of that binary pulsar was a prime motivation and justification for building the new detector array, called LIGO. It demonstrated that rapidly rotating binary stars do emit gravitational waves, and therefore a design such as LIGO will indeed make detections, if it could be built to the claimed sensitivity. That has now been accomplished.
The fact that the signal was seen in two detectors (one in Washington and one in Louisiana) was absolute critical to their announcement. If it had been seen in only one, there is not sufficient surety of the signal behavior to enable it to be verified as a gravitational wave. The fact that it was seen on two detectors also allows us to determine the direction to within a band on the sky, the center of the band determined by the relative arrival time at the two detectors, and the width of the band determined by the uncertainty in that arrival time.
Unfortunately, that same event is a one-timer, so it will not be seen again. (It would be great if it were! That would indicate something unexpected.) If it were seen again, as the Earth rotates, it would be a different band on the sky, and the intersection of the two bands would allow us to locate it to within two small regions; regions that could be examined optically.
It is unfortunate to see so much discussion online about a Nobel Prize. No fundamental discovery has been made -- yet. An elegant and clever instrument was built that does what it was meant to do, and it made an observation. The discoveries are yet to come. LIGO may change our understanding of the dynamics of black holes, of gravity waves, and of the nature and make-up of the Milky Way galaxy. It hasn't done so yet, but the odds are in its favor.
This is so exciting!It sounds like they had indirect proof of it, but this is the first direct proof of waves.
It's amazing that they've finally found them, I can't wait to see what else they'll discover now they know how to do it!

SpaceX is hoping to do the Static fire test for the Ses-9 mission today, with launch windows on wensday and thursday.I have faith!
Launching from florida, with the landing attempt on a drone ship. although ive heard that landing of the first stage will be dubious because of the launch profile. something about it putting the first stage right around the edge of its survivalbility on re-entry
I have faith!i think opposite lol they have got really good at getting it to the pad, and would have made the last one if it wasnt for the hardware fail, that aslong as it survives re-entry after stage seperation, i think they will land it. If something fails it will be under the high stress while it still has all that velocity lol
SpaceX has gotten really good at reaching the landing pad successfully. Any failure I bet would occur at the last second.

I'll bet $1,000 it makes it.im not 100 percent sure, but i think it has like 2-3000kph more then the orbbcom landing lol if they pull it off itll be amazing.
im not 100 percent sure, but i think it has like 2-3000kph more then the orbbcom landing lol if they pull it off itll be amazing.But does that extra speed matter? All previous problems have happened once the rocket was slowed down. They've yet to fail with getting the rocket to target.
ill bet we loose feed just before it lands ;)

I learned something I didn't know, maybe if it's taught in chemistry? But Uranium will change 14 times over it's lifetime eventually turning into Lead. Pretty cool stuff.That's physics. Its different types of radioactive decay. It emits alpha or beta particles in an attempt to become more stable. Lead has the highest proton number (82) of all the stable atoms so everything with more than that emits these particles to try and become lead. Some isotopes of lead are still unstable though. Uranium is quite far away so it has to decay 14 times.
I learned something I didn't know, maybe if it's taught in chemistry? But Uranium will change 14 times over it's lifetime eventually turning into Lead. Pretty cool stuff.Yeah, like the exact opposite of stars turning hydrogen into heavier elements.
Yeah, like the exact opposite of stars turning hydrogen into heavier elements.? They said Uranium was created from an exploding star. At least what we have here on earth.
? They said Uranium was created from an exploding star. At least what we have here on earth.Yeah the super heavy elements are created from supernovas, but lighter elements are created by fusion in the core.
I learned something I didn't know, maybe if it's taught in chemistry?Physics or Chemistry.
Physics or Chemistry.yeah, I didn't take either class. I know the periodic table was taught in general science class but it didn't go deep into it.
Some of that stuff actually ends up getting taught in both.
Yeah, like the exact opposite of stars turning hydrogen into heavier elements.I'm guessing you're referring to fission here and that's not technically true. Uranium does fission but that only happens when we cause it by firing neutrons at it and it will make much smaller atoms than lead so its not really a decay chain.
? They said Uranium was created from an exploding star. At least what we have here on earth.That's how all naturally occurring elements (all up to Uranium in the periodic table) are made. Stars are big spheres of hydrogen gas that have such a huge temperature (due to the gravity) that hydrogen atoms get fused together when they hit each other. This makes Helium. When a star is alive it makes a few of the smaller elements by fusion, usually up to about carbon.
Uranium has 92 protons, if you try to make an element with any more then it is extremely unstable and decays almost instantly, hence Uranium is the biggest element we can find on Earth.Some isotopes of Plutonium have long-ish half lives.
I'm guessing you're referring to fission here and that's not technically true. Uranium does fission but that only happens when we cause it by firing neutrons at it and it will make much smaller atoms than lead so its not really a decay chain.Nah didn't mean fission, although that'd be even more of an exact opposite.
Its used for dating aswellI expected that to lead into a joke!
Some isotopes of Plutonium have long-ish half lives.Yeah some of them do have fairly long half lives but not long enough for us to be able to find them naturally on Earth.
Uranium 238 has a super super long half life though.
Nah didn't mean fission, although that'd be even more of an exact opposite.your moms age is no laughing matter..
I expected that to lead into a joke!
Nah didn't mean fission, although that'd be even more of an exact opposite.Yeah I guess. I wouldn't really consider alpha/beta decay opposite to fusion though because they're very different processes but they sort of do the opposite things. Fusion increases proton/ nucleon number while alpha reduces it. Beta can reduce or increase proton number while nucleon number always remains the same, so that definitely isn't opposite to fusion!
I expected that to lead into a joke!
@XevrossAs far as I understand it, due to the standard model and the nuclear forces, the larger elements can never be stable.
What are your thoughts on larger elements being potentially stable? Is that something they think still might be possible?
Same! Were you referring to carbon dating there, DD?Potassium and Uranium are also used (fairly regularly) for dating.
That is, unless something radical and crazy gets invented which allows us to artificially change nuclear forces. That would be awesome. Very unlikely though.SuperGravity.
Potassium and Uranium are also used (fairly regularly) for dating.True true. I've only ever learned about carbon dating though. ::)
SuperGravity.Its interstellar all over again!

Fusion increases proton/ nucleon number while alpha reduces it. Beta can reduce or increase proton number while nucleon number always remains the same, so that definitely isn't opposite to fusion!the first post was about radiometric dating, whenever i hear about the decay chain it makes me think of that. especially since i have literally had arguments with people about if it is accurate. sometimes with face palms when they say we cant know that the half lives werent alot shorter in the past.
Same! Were you referring to carbon dating there, DD?
As far as I understand it, due to the standard model and the nuclear forces, the larger elements can never be stable.
They're unstable because the electrostatic force pushing the protons away from each other is too large for the strong nuclear force. At Uranium and below the SNF is just strong enough to hold the nucleus together against the EF. However at 93 protons and above the EF is always too strong and the SNF can't hold it together. Due to the way the universe is and how science works, I don't think we'll ever be able to overcome this.
That is, unless something radical and crazy gets invented which allows us to artificially change nuclear forces. That would be awesome. Very unlikely though.
Really like the contrast in this video, showing the advanced rocket in an empty field.i saw that yesterday and noticed that to lol
Woah this IS magic.Magnets are super cool.
Does anyone know what kind of or how powerful a telescope has to be to focus the light of a star on to a prism?Can you specify? You'd need to work out a load of things like distance between the lenses of the telescope and the prism
Can you specify? You'd need to work out a load of things like distance between the lenses of the telescope and the prismBasically I want to do it. But. Don't know where to start. I wanted to see the "code" of a start for my self. I forgot the real name of it. But basically if you look at star light threw a prism then magnify the light from the prism, you'll be able to see black linescreen in between the colors.

$100 Million Plan Will Send Probes to the Nearest Star
Funded by Russian entrepreneur Yuri Milner and with the blessing of Stephen Hawking, Breakthrough Starshot aims to send probes to Alpha Centauri in a generationhttp://www.scientificamerican.com/ar...-nearest-star/ (http://www.scientificamerican.com/article/100-million-plan-will-send-probes-to-the-nearest-star/)QuoteFor Yuri Milner, the Russian Internet entrepreneur and billionaire philanthropist who funds the worlds richest science prizes and searches for extraterrestrial intelligence, the sky is not the limitand neither is the solar system. Flanked by physicist Stephen Hawking and other high-profile supporters today in New York, Milner announced his most ambitious investment yet: $100 million toward a research program to send robotic probes to nearby stars within a generation.
QuoteBreakthrough Starshot, the program Milner is backing, intends to squeeze all the key components of a robotic probecameras, sensors, maneuvering thrusters and communications equipmentinto tiny gram-scale nanocrafts. These would be small enough to boost to enormous speeds using other technology the program plans to help develop, including a ground-based kilometer-scale laser array capable of beaming 100-gigawatt laser pulses through the atmosphere for a few minutes at a time, and atoms-thin, meter-wide light sails to ride those beams to other stars. Each pinging photon of light would impart a slight momentum to the sail and its cargo; in the microgravity vacuum of space, the torrent of photons unleashed by a gigawatt-class laser would rapidly push a nanocraft to relativistic speeds.I want to believe.
Deployed by the thousands from a mothership launched into Earth orbit, each nanocraft would unfurl a sail and catch a laser pulse to accelerate to 20 percent the speed of lightsome 60,000 kilometers per second. Using a sophisticated adaptive-optics system of deformable mirrors to keep each pulse coherent and sharp against the blurring effects of the atmosphere, the laser array would boost perhaps one orbiting nanocraft per day. Each laser pulse would contain as much power as that produced by a space shuttle rocketing into orbit.
ESA Science & Technology: Venus Express' swansong experiment sheds light on Venus' polar atmosphere (http://sci.esa.int/venus-express/57735-venus-express-swansong-experiment-sheds-light-on-venus-polar-atmosphere/)What's the temperature on land though? The paper referenced was talking about the atmosphere.
so apparently venus has frozen poles.. wouldnt it make it a hell of alot easier to land?
What's the temperature on land though? The paper referenced was talking about the atmosphere.it doesnt say, but even having the cooler atmosphere would make probes last longer going down, any little bit helps.

Tacos, how does one get into a Airplane type job?Is he an engineer? Of so it would be pretty easy.
I have a friend who wants to be able to build airplanes. (Well he kind of is right now.) But he wants to get a job in that. It's been my understanding that Mechanical Engineers can get jobs in the field, but aeronautical engineers may be better.
Any idea?
Is he an engineer? Of so it would be pretty easy.He wants to go to school for Engineering, deciding between mechanical and aeronautical.
If he want to actually build them then there's schools to get an A&PC license. Which cost way to much. It's actually easier to sign up at a contract house. And say he has a year of experience, even if he doesnt. Contract house won't check. Then once he gets a gig he can use that as experienced and go from there. But don't lie about an A&P
That will be checked.
He wants to go to school for Engineering, deciding between mechanical and aeronautical.Alright, then he will be fine. It's still hard to get a job with out any experiance, but his school might be able to place him somewhere. I got lucky and they took my Autobody experience. So I didn't have to go to school for any of it. I'm pretty Sure I could go take the A right now and pass it. The P would be a bit harder, but with some study I could pass that too. It's just these schools don't like people to just take the test, So they are dicks when you do it with out the school and are harder on you when you go to the practical part of the test.
Right now he's finishing an A&P program.

spacex fb said next launxh in 10 days.. what ia schedule next, eutelsat or thaicomThiacom.
Thiacom.thanz i got a good feeling about that one since its relatively light
thanz i got a good feeling about that one since its relatively lightWell after this past one, I've got a good feeling about all of them.
and it looks like we gotta wait till tomorrow for news on thaicoms static fire.At least the date hasn't slipped.
At least the date hasn't slipped.that would have been really cool to see, but could also be a good thing it never had to ;)
In other space news, I just read that the Space Shuttle was forced by the military to be capable of capturing foreign satellites and returning them to Earth. That would have been pretty cool to see.
will the iss have live video? lol
Ready for tomorrow.
Also beam is expanding in a few hours, just a reminder.
will the iss have live video? lolYeah NASA tv on youtube should have it live.
i have to pick up my kids from school just as it launches :( imma miss this one :(
Yeah NASA tv on youtube should have it live.yea i missed jason 3 aswell lol im so mad im going to miss it, I might get lucky and be able to get it on my phone lol
The Jason 3 rocket was the only one I've missed since I started watching them. In a way I was kinda happy when it didn't land >:D
30 minutes till launch. Guess I might be the only one here watching today :Pim followig on my phone lol im hoping ill get ti steal wifi when i drop my gf at work lol
im followig on my phone lol im hoping ill get ti steal wifi when i drop my gf at work lolDELAYED!!!
DELAYED!!!ooooo whats up?Spoiler for Hidden:
ooooo whats up?No clue yet, but at the moment everything with the rocket seems fine.
No clue yet, but at the moment everything with the rocket seems fine.just saw that on NSF forum. im on her works wifi lol ill be home then for it !

Rosetta's comet contains ingredients for life / Rosetta / Space Science / Our Activities / ESA (http://www.esa.int/Our_Activities/Space_Science/Rosetta/Rosetta_s_comet_contains_ingredients_for_life)hows the weather look? i heard its 60percent
Also the falcon just went vertical. Might actually be launching in 2 hours.
hows the weather look? i heard its 60percentYeah 60.
Rocket landing speed was close to design max & used up contingency crush core, hence back & forth motion. Prob ok, but some risk of tipping.
— Elon Musk (@elonmusk) May 27, 2016
Crush core is aluminum honeycomb for energy absorption in the telescoping actuator. Easy to replace (if Falcon makes it back to port).

Musk: SpaceX could take humans to Mars in 9 years - Jun. 2, 2016 (http://money.cnn.com/2016/06/02/news/companies/musk-mars-2025/index.html?sr=fbCNN060216musk-mars-20250705AMVODtopLink&linkId=25100607)Crazy.
Musk reiterated confidence in his Mars timeline at the Code Conference on Wednesday night.
"If things go according to plan, we should be able to -- we should be able to -- launch people in 2024, with arrival in 2025," Musk said.
"That's the game plan," he added.
Crazy.my guess would be MCT. itll be unveiled in sept, so thats lots of time to get it ready.
Is he planning to have BFR human certified by then or will the first landing be with the help of multiple Falcon Heavys?
my guess would be MCT. itll be unveiled in sept, so thats lots of time to get it ready.Revealed in Sept but manufacturing and testing will take a while. Could be close!
itll beat nasa by like a decade lol
Revealed in Sept but manufacturing and testing will take a while. Could be close!man they need to figure out a way to bring those back in a less precarious manner. lol
Also don't fall over!!!
eutelsat apparently moved up to the 14th. 1030am est early launchYay!
That's a good sign!

Sometimes I wonder about time constraints for AI.I think it's more likely the first AIs will be built intelegent from day one. Instead of being babies learning through play, they'll be adults learning through observation. IE Siri and Cortana learning through day to day operation.
Babies have like a decade or two to learn lots of stuff, and they get to play around the real world, being able to touch, smell, play around with physics, taste, etc.
AI don't exactly have the ability to do really any of that stuff, while they do have their own benefits with tons of access to other types of information. But I wonder.
I think it's more likely the first AIs will be built intelegent from day one. Instead of being babies learning through play, they'll be adults learning through observation. IE Siri and Cortana learning through day to day operation.This 100% seems to be the direction that we are going. Don't see any indication something else will come up.
Baby like AI learning seems like something that'll come after first gen AI, where seeking human like sentience is the primary goal.Current AI is pretty cool, but so much of it seems problematic. Even Microsoft's twitterbot, and most of the best bots still are not really great.
This 100% seems to be the direction that we are going. Don't see any indication something else will come up.One AI concept I've had is ignoring the complex parts of consciousness and just try to make a program that predicts what a human would do. IE scan through every single post of a person online, calculate how they write and how they feel, and then simulate that person's online presence. To outsiders if the algorithm is good enough, it'd feel like AI. Yet on the programing side it'd have zero understanding of what it's actually saying or "thinking."
Current AI is pretty cool, but so much of it seems problematic. Even Microsoft's twitterbot, and most of the best bots still are not really great.
I think it'd be interesting if there was some amazing algorithm that just required something different from what has really been tried in the field. Like giving it more time, and giving it like a playground.
Even if we had like a virtual playground, and virtually sped up time for an AI, I wonder if there could be some amazing way for Ai's to learn.
I also think it'd be cool if we could like extract personalities from other sources and apply it to an Ai. Like "Can we make a Homer Simpson AI?" and then the computer does analyzing on the show and makes something true to that character.
Think that'd be cool, but I can't imagine that happening (any time soon at least).
bad feeling about it.. that was a hell of alot of smoke..Yeah it looked like it was standing fine, but that fire seemed large and the video didn't cut back in.
Yeah it looked like it was standing fine, but that fire seemed large and the video didn't cut back in.where do you get the info on explosion, replay clips show an object standing upright, you can see the straight line of the core.
Probably fell over and exploded.
EDT: yup exploded. loss of signal.
where do you get the info on explosion, replay clips show an object standing upright, you can see the straight line of the core.I think it caught on fire and burnt up. LOS is the official part.
Landing video will be posted when we gain access to cameras on the droneship later today. Maybe hardest impact to date. Droneship still ok.

ya. calling it a second qualification test.Worked perfectly.
Worked perfectly.some kind of northern lights for jupiter?
Also
some kind of northern lights for jupiter?Yup. Infrared photo overlayed on a true color photo, or some thing like that.
The auroras were photographed by Hubble during a series of observations of Jupiter made in far ultraviolet-light. The full-color disk of Jupiter used in the image was photographed separately by Hubble at an earlier time.CNN (http://www.cnn.com/2016/07/01/health/hubble-jupiter-juno-auroras/)
To gain more data on the auroras, the Hubble Space Telescope has been staring at Jupiter for 45 minutes every day for the past month. At Earth, auroras light up when solar wind particles slam into molecules of air near the polar regions. At Jupiter, the charged particles come mostly from a different source: the volcanos of Io. Jupiter's powerful magnetic fields then accelerate the particles into the planet's atmosphere.NYT (http://www.nytimes.com/2016/07/01/science/jupiter-nasa-juno-hubble.html)
On Earth, auroras appear over an area about as large as the United States. Jupiter's auroras, like everything else there, are vastly larger, about as wide as five Earths.
"But we've never been able to get up close and really observe these processes," Fran Bagenal, a professor of astrophysical and planetary sciences at the University of Colorado and one of the mission scientists, said at the news conference. "So we can then compare them with what we see at Earth, what we seen at Saturn."
During World War II, Wald applied his statistical skills when considering how to minimize bomber losses to enemy fire. Researchers from the Center for Naval Analyses had conducted a study of the damage done to aircraft that had returned from missions, and had recommended that armor be added to the areas that showed the most damage. Wald noted that the study only considered the aircraft that had survived their missions--the bombers that had been shot down were not present for the damage assessment. The holes in the returning aircraft, then, represented areas where a bomber could take damage and still return home safely. Wald proposed that the Navy instead reinforce the areas where the returning aircraft were unscathed, since those were the areas that, if hit, would cause the plane to be lost.Kind of a fun story.
Kind of a fun story.Clever people can be very clever sometimes.
Clever people can be very clever sometimes.Seems a bit of common sense really.

Link. (https://www.eso.org/public/news/eso1624/) Searched and didn't see a thread.What the orbit might be like (YT video). (https://www.youtube.com/watch?v=SrzJEkovZLw)Quote
QuoteLuke Skywalker's home planet, Tatooine, in the Star Wars saga, was a strange world with two suns in the sky, but astronomers have now found a planet in an even more exotic system, where an observer would either experience constant daylight or enjoy triple sunrises and sunsets each day, depending on the seasons, which last longer than human lifetimes. This world has been discovered by a team of astronomers led by the University of Arizona, USA, using direct imaging at ESO's Very Large Telescope (VLT) in Chile. The planet, HD 131399Ab (1), is unlike any other known world -- its orbit around the brightest of the three stars is by far the widest known within a multi-star system. Such orbits are often unstable, because of the complex and changing gravitational attraction from the other two stars in the system, and planets in stable orbits were thought to be very unlikely. Located about 320 light-years from Earth in the constellation of Centaurus (The Centaur), HD 131399Ab is about 16 million years old, making it also one of the youngest exoplanets discovered to date, and one of very few directly imaged planets. With a temperature of around 580 degrees Celsius and an estimated mass of four Jupiter masses, it is also one of the coldest and least massive directly-imaged exoplanets."For about half of the planet's orbit, which lasts 550 Earth-years, three stars are visible in the sky; the fainter two are always much closer together, and change in apparent separation from the brightest star throughout the year," adds Kevin Wagner, the paper's first author and discoverer of HD 131399Ab
QuoteAlthough repeated and long-term observations will be needed to precisely determine the planet's trajectory among its host stars, observations and simulations seem to suggest the following scenario: the brightest star is estimated to be eighty percent more massive than the Sun and dubbed HD 131399A, which itself is orbited by the less massive stars, B and C, at about 300 au (one au, or astronomical unit, equals the average distance between the Earth and the Sun). All the while, B and C twirl around each other like a spinning dumbbell, separated by a distance roughly equal to that between the Sun and Saturn (10 au). In this scenario, planet HD 131399Ab travels around the star A in an orbit with a radius of about 80 au, about twice as large as Pluto's in the Solar System, and brings the planet to about one third of the separation between star A and the B/C star pair. The authors point out that a range of orbital scenarios is possible, and the verdict on the long-term stability of the system will have to wait for planned follow-up observations that will better constrain the planet's orbit.

So is it a launch and then goes into a landing soon after or is this just launch for something else?Launch in 50 minutes. Then a few minutes after launch the second stage separates. That continues to the ISS while the first half turns around and goes back to Florida. That landing attempt will be part of the livestream too.

interesting. i wonder what they have to say. any rumors?Probably just share some details.
Well that was crazy.
Got out of the car and looked up in the night sky like I usually do. Instantly spotted a faint satellite moving slowly since it was passing next to a planet. Within a second of spotting it, the satellite turned on a dime and launched roughly 90 degrees in a different direction and zoomed out of sight. WTF!?!? Took a while just staring at the sky coming to terms that what I witnessed was real and wasn't my brain doing any tricks. Whatever I saw, I really saw it. But since I'm a man of science and kept staring in the sky, I noticed the original satellite emerge from behind a tree and along its original course. Yay mystery solved! A second object, probably a shooting star, just happened to appear at the exact same spot as the satellite was. Since the second object was much brighter, it hid the original one and my brain tracked it as if they were the same thing. Was flipping cool.

isnt Isp a measure of how much momentum change can be done for a given fuel unit? so the higher it is, the more efficient lol or thats atleast how i understand it lol
What a wonderful tease for tomorrow!
Raptor is highly needed for SpaceX. Current second stage on Falcon 9 gets isp 348 in space while this one is 382 in space. Now I don't actually know what these numbers mean, but Kerbal Space Program tells me the second is a lot more efficient. A falcon 9 with a raptor second stage could significantly increase its load. Same with a Falcon Heavy.
Plus this is the engine that will send us to Mars.
isnt Isp a measure of how much momentum change can be done for a given fuel unit? so the higher it is, the more efficient lol or thats atleast how i understand it lolYeah I think so. I just know higher isp is all that matters once my rockets reach space. ::)
Yeah I think so. I just know higher isp is all that matters once my rockets reach space. ::)haha ya that was my working definition. but ive been trying to understand the math behind it more lately. when i saw him say 382 i was impressed.
haha ya that was my working definition. but ive been trying to understand the math behind it more lately. when i saw him say 382 i was impressed.I just went off wikipedia.
and i thought the merlin D had a isp lower than 350. i heard around 312. either way 382 is a much needed upgrade.

Way more chill than a SpaceX launch. IMO it'll probably still launch.
any news on why the hold? lolApparently it was because they called the first hold lol. Rocket time was offset so they just restarted the launch cycle to fix it.
Successfully escape and successful landing. Congrats.i had to drive kids to school so i missed it, but watched the reply. i agree with the announcers, very little enthusiasm from them lol
These announcers just come across as so "scummy" though. Was I watching a rocket test or an infomercial?
so SpaceX has given more word on what happened to AMOS-6 on the pad.Yup I'm glad it wasn't part of the rocket. Still a problem, but should be cheaper to fix.

Anyone checking out the super moon? I tried to take a photo but my camera sucks for night shots . last one till 2033.I guess I'll go outside just to say that I did it.
I guess I'll go outside just to say that I did it.Is it as super as you expected?
Is it as super as you expected?like 30 percent more super.
like 30 percent more super.Looks really bright tonight though.
Doesn't look that big to me. I think it's bigger, but maybe not..
like 30 percent more super.Yeah that's why supermoons really aren't that interesting. The difference in size is negligible compared to other factors that make the moon feel big or small.

"Politically correct environmental monitoring" (https://www.theguardian.com/environment/2016/nov/22/nasa-earth-donald-trump-eliminate-climate-change-research?utm_source=dlvr.it&utm_medium=twitter)...Now I've heard everything.QuoteDonald Trump is poised to eliminate all climate change research conducted by Nasa as part of a crackdown on politicized science, his senior adviser on issues relating to the space agency has said.Nasas Earth science division is set to be stripped of funding in favor of exploration of deep space, with the president-elect having set a goal during the campaign to explore the entire solar system by the end of the century.
QuoteThis would mean the elimination of Nasas world-renowned research into temperature, ice, clouds and other climate phenomena. Nasas network of satellites provide a wealth of information on climate change, with the Earth science divisions budget set to grow to $2bn next year. By comparison, space exploration has been scaled back somewhat, with a proposed budget of $2.8bn in 2017.
Bob Walker, a senior Trump campaign adviser, said there was no need for Nasa to do what he has previously described as politically correct environmental monitoring.
We see Nasa in an exploration role, in deep space research, Walker told the Guardian. Earth-centric science is better placed at other agencies where it is their prime mission.
My guess is that it would be difficult to stop all ongoing Nasa programs but future programs should definitely be placed with other agencies. I believe that climate research is necessary but it has been heavily politicized, which has undermined a lot of the work that researchers have been doing. Mr Trumps decisions will be based upon solid science, not politicized science.
Walker, however, claimed that doubt over the role of human activity in climate change is a view shared by half the climatologists in the world. We need good science to tell us what the reality is and science could do that if politicians didnt interfere with it.
QuoteMichael Mann, a climate scientist at Penn State University, said Nasa has a critical and unique role in observing Earth and climate change.https://www.theguardian.com/environm...medium=twitter (https://www.theguardian.com/environment/2016/nov/22/nasa-earth-donald-trump-eliminate-climate-change-research?utm_source=dlvr.it&utm_medium=twitter)
Without the support of Nasa, not only the US but the entire world would be taking a hard hit when it comes to understanding the behavior of our climate and the threats posed by human-caused climate change, he said.
It would be a blatantly political move, and would indicate the president-elects willingness to pander to the very same lobbyists and corporate interest groups he derided throughout the campaign.
Climate change research is on the way out. Net neutrality looks to be on the way out.... Whats next?Mars is still on the books!
Climate change research is on the way out. Net neutrality looks to be on the way out.... Whats next?Creationism in public education? At least, Mike Pence would love for that to happen :P

It feels weird to imagine being in another universe with different laws of physics.Aw man I remember reading about some book/project where the author changed some fundamental concept to negative and then rebuilt everything around that. I'm trying to find a link.
Like with different constants for gravity and such.
Like literally could be like walking through a doorway and shrinking or growing or exploding.
Feels weird to think of matter properties being dependent on the universe's properties. You can't really separate the two.

hes so dumb, god i hate trumpCutting ARM is actually good imo. People have wanted it and SLS cut for a long time.
Cutting ARM is actually good imo. People have wanted it and SLS cut for a long time.i liked the idea of ARM, it would have been really cool.
Each SLS launch will cost half a billion yet only the later versions will be significantly stronger than Falcon Heavy. The 3-stage New Glenn from Blue Origin will be comparable to the SLS block 1 as well.
i liked the idea of ARM, it would have been really cool.I think the original thing would have been really cool.
Trump released plans for NASA's budget.The really shame news is that 4 of NASA's climate change projects will be cancelled. I think that might be all of their climate change work.
Asteroid Redirect Mission is cut. If you don't remember, that was the plan to break a rock off an asteroid and put it into lunar orbit. Then astronauts on SLS would go study it. The original plan was to send astronauts to an actual asteroid but it had been repeatedly watered down over the years.
Now without ARM, SLS will realistically only be used for the Europa Clipper in 2022 and a test launch next year. Will be cool to see the rocket fly but my gosh is it an expensive waste of time.
(congress might ignore Trump and keep ARM. They regularly did that with Obama and gave NASA more money)
The really shame news is that 4 of NASA's climate change projects will be cancelled. I think that might be all of their climate change work.Yeah planetary science is a big big loss with this proposed budget. Hopefully congress ignores that part but I'm not sure that's likely. Most NASA funding increases from congress have been for crewed and deep space exploration.

While there was no actual positive sign for any of the targets, they got some potentially 'false positives', and guess which star showed up... yup.

I Can't wait for self driving cars. It'll be so fun to have all that extra time.Same! I don't see the point in learning to drive with how close they are now.

If self driving cars turn evil, we will have to learn how to drive once more.I'd trust evil self driving cars more than humans
The war hasn't begun yet, but we must be ready.
Same! I don't see the point in learning to drive with how close they are now.It'll be a long time before you can be in the driver's seat without a license. If something goes wrong, you're considered responsible.
It'll be a long time before you can be in the driver's seat without a license. If something goes wrong, you're considered responsible.I thought they were already pushing for the cars to be recognised as drivers on their own

That requires changes to laws and those are always slow, at least on our side of the pond.Yeah I know that but I thought that they're working on those laws right now. I know the UK government has just invested a large amount of money into driverless cars, I'd wager they'll want to push the laws through sooner rather than later if they can.
Yeah I know that but I thought that they're working on those laws right now. I know the UK government has just invested a large amount of money into driverless cars, I'd wager they'll want to push the laws through sooner rather than later if they can.In America practically everyone who can afford a self driving car will already have a driver's license. Even if our government was investing in the cars, it wouldn't be a large priority to remove the license restriction.
Also I'm not actually planning on not learning to drive because I'm waiting for driverless cars, I just have no reason to learn with being at Uni for the next 3 years and not being able to afford a car or insurance anyway. I think I'm gonna consider it in a couple of years and see if I think its worth it.
Same! I don't see the point in learning to drive with how close they are now.Not that close even further away if you wanted Envision it like the movies.
There are languages that have absolute direction. Instead of left/right, they need to know exactly what direction they are looking at all times. Their brain takes care of this for them.Yeah that's a fun thing to learn about. Languages are crazy.
It'd be cool if there were languages that knew exact colors.
Yeah that's a fun thing to learn about. Languages are crazy.I believe there have been studies about how language affects how we view the world, at least this specific example:
No such thing as exact colors in natural language though. Often it's the opposite. Languages "start" with just three colors: lightish, darkish, and redish. Everything fits as a variant of one of the three and they don't think any others would make sense.
I believe there have been studies about how language affects how we view the world, at least this specific example:Yeah it also changes how we classify things.
Spanish speakers pick up what an object is before it's color, and English speakers are the opposite. I don't know how true it is.
Languages obviously teach people to discriminate between colors.
English - red/pink
Russian - light blue/dark blue
It'd be kind of cool if there was some sort of like maximum point of discrimination where someone could back track any color to a wavelength or something crazy like that.

Why try and prove something which everyone knows is true already, and has been proven by other people before in the same/ different ways. Its a complete waste of time.

Plus, you can build stuff!
For realsies, there's a lot of big new math discoveries! Fermat's last theorem was only discovered in 1994. The poincare' conjecture was also proven in 2006.
There are lots of big math problems like Riemann's hypothesis, P vs NP, etc; that still need solving.
Math is all about puzzles. Some of those puzzles have huge implications for things like physics, computer science. Some of them are just interesting in their own right.
Some of them are interesting in their own right, then 50 years later we find out they have applications in other fields.
Making connections is fun, regardless of who did it before you.
Yeah I know that a lot of it is useful, but I'm talking more about university / college level stuff than cutting edge research.Well, at that level, the fun is more about the beauty of math. And seeing how stuff fits together.
I just don't like it at all, and its extremely far from being fun.Well, I don't think you've even really done any math I'd consider fun anyways.
Well, at that level, the fun is more about the beauty of math. And seeing how stuff fits together.My maths analysis course last year is the most pure math course I did. It was on set theory, epsilon proofs and stuff like that. I absolutely despised it.

Eh, I'd argue that pure math doesn't really exist the way some people think of it.I'm not arguing about importance or anything. Its just the maths that you'd generally call 'pure maths' I usually don't like/hate, and the maths you'd generally call 'applied maths' I usually love. Plus applied maths has a lot more interesting applications in physics.
It's just some people think their math is more important because it has practical applications.
But "pure" math also has a lot of applications itself.
Mathematicians in "pure maths" and "applied maths" use plenty of the other.

I think it's cool that lots of applied math started out as pure math.Yeah, pure math is just applied math that hasn't found its purpose yet!
It's like half the puzzle is finding new math, and the other half is finding that math in nature.
4x4 determinants make me hate math.Yeah haha they suck. I was programing my own 4x4 class the other day and ended up saving time by creating a little loop that'd output the formula with my variables. Would have sucked to have had to type it out, and yet that'd be trivial compared to doing calculations on paper like you did.
The two bottom rows were all functions. One row looked like e^(ika-ib) for every function. The other looked like (ika-ib)e^(ika-ib) for every function.
There were also no 0's anywhere.
I filled up like 2 pieces of paper, front and back of both. Made a mistake, and had no time to fix it.
I really like my number theory class though.So useful in programing too.
The big thing in a lot of the class is modulus.
So like 7=2(mod 5)
Basically it looks at the remainder of what's left after dividing. It's this: %
But it has a ton of really useful properties and connections with prime numbers.
I am doing an assignment for QM and have to give 3 reasons why electron classically spinning doesn't make sense.Is it because electrons are fundamental particles and as such can't have a forward defined? Or can fundamental particles have a non uniform shape/property?
I've looked through like 20 books, as it's supposed to be cited. Like 10 of them don't give a reason, 8 of them give the reason and it's an awesome reason, and the other 2 give another reason and it doesn't really make a whole lot of sense.
No third reason anywhere.
It's also kind of annoying to see the same few lines in every book.
Is it because electrons are fundamental particles and as such can't have a forward defined? Or can fundamental particles have a non uniform shape/property?Some books will simply say it is a point particle and therefore spinning doesn't make much sense; which I think in a sense fits your explanation.

Have you seen an Iridium flare yet?
Nope, Thats one phenomenon i would love to see. but dont get out enough to really look. i wanna move close to my work, and closer to a "night park" our city has thats tucked between mountains and reserved for star gazing etc.You need to use an app for Iridium flares since they're so rare yet highly predictable. There's a big piece of reflective metal on the old Iridium satellites and the "flare" is when they reflect the sun directly towards your location on the ground. I've only seen one and tbh it wasn't that amazing but it was still pretty cool and brighter than the ISS.
I was thinking about planck length and how since it's the smallest unit possible, it'd have to define a universal reference point.Why would that follow?
Why would that follow?Because then the world would have to be "voxel" like and objects would have to bounce from spot to spot. This fundamental grid would be defined with its own default velocity.
Because then the world would have to be "voxel" like and objects would have to bounce from spot to spot. This fundamental grid would be defined with its own default velocity.I see what you mean .
I see what you mean .I watched this a while ago
Each piece of paper is about 2000 bytes. 1 tb contains 1e+12 bites bytes of data. 1 trillion divided by 2000 is about 500 million, so 1tb would be about 500 million piece of paper.
Your average piece of paper is about .1mm thick. That means your stack of paper is about 500,000 meters tall. (1640419.95 feet for us freedom lovers). Thats 310 miles tall.
In comparison the ISS is only about 249 miles tall high. But since he's got two stacks of paper, he's only going up about 160 miles. He couldn't breathe and would need a space suit.
His tower would cost a lot. A sheet of paper is about 6 cents. That means for his 500 million sheets its gonna cost about 30 million dollars, however, that pales in comparison to his 85.7 billion net worth. (In fact, its only 0.035 percent of his net worth.)
The tower would also weigh a lot. Each sheet of paper weighs about .16 ounces, making the tower weigh 80 million ounces. Thats 5 million pounds, or about 108 fully loaded 747s. Even more surprising, that surpasses how much OPs mom weighs by about 1 million pounds
edit:
Some disagree on the price. This was the first thing that popped up on google when I searched for price of a piece of paper. On second glance, it appears that it might be including the cost of the ink. (Going off of price of wasted page.) Given that the point of the drive is to store the text, when that text would have to be printed, I think the number is still right; but it includes ink.
Byte was spelled as bite a few times, this has been fixed.
Yes, the ISS is 249 miles high, not tall. (Just like r/trees)
edit #2:
I fat fingered the weight of a 747 when typing into calculator. We are looking at closer to 5 fully loaded 747s.
As some have pointed out there may have been another fat fingering in the 10s place for the weight. working on that right now
edit #3:
There was fat fingering on the weight/height. I am off by a factor of 10. Stack is only 50,000 meters (31 miles) tall, and only weighs 500,000 pounds. The stack only weighs half of a 747, but is still taller than mount everest, the heights your airliner flys at, and pretty much everything that isn't the ISS or a satellite. You would still need a space suit
edit #4:
More fat fingering being done here than OPs mom in an orgy
Thinking about this, could every single word ever written on paper in history fit on a smartphone? It'd need to be compressed heavily.I feel like this is really difficult to quantify.

How many Planets are there in the Solar System :: The Planets Today (https://www.theplanetstoday.com/how_many_planets_are_in_the_solar_system.html)dang that's a pretty cool simulation of the movements of the planets. Funny seeing how slow the outer planets are compared to the inner one.
I knew about Ceres but I had no idea that so many other bodies were thought of as planets. Wonder if it'll bump back up in the near future with the potential planet past Pluto.
A curious situation. The best known lower bound for the minimal length of superpermutations was proved by an anonymous user of a wiki mainly devoted to anime. https://t.co/z3wVAcUJl1

I was thinking about planck length and how since it's the smallest unit possible, it'd have to define a universal reference point. Then I went to Wikipedia and found out it's a common misconception and planck length isn't the smallest unit.I should really click this thread more! As a physics student I cried a little reading this. "smallest unit" really doesn't make any sense. You can always go smaller if you had a way to measure that small.
TIL
I should really click this thread more! As a physics student I cried a little reading this. "smallest unit" really doesn't make any sense. You can always go smaller if you had a way to measure that small.Yeah, but to be fair a lot of small stuff doesn't make any sense.

Yeah, but to be fair a lot of small stuff doesn't make any sense.Well it kinda makes sense, in that you can understand the explanation of it... but thinking about the universe actually acting that was is super weird. Small stuff is super odd to be sure.
Like the Heisenberg uncertainty principle.

Well it kinda makes sense, in that you can understand the explanation of it... but thinking about the universe actually acting that was is super weird. Small stuff is super odd to be sure.String theory is in a weird spot. Mathematically it's an awesome theory but so far it hasn't made any predictions that we could test. If it was really how the universe worked, you'd think after all this time it'd at least have some supporting evidence.
I really don't know much about string theory. There's a lot of odd theories out there.

It seems more likely to me that the issue is simply that society building organisms are rare, perhaps extremely. We see this on our planet, there are thousands and thousands and thousands of species, trillions of organisms, that we share this planet with and none, but us, carry a lasting multi-generational record of knowledge of any obvious consequence. Human beings have gone beyond being biological organisms and become the cells of an informational organism. A human being left in the woods from birth to death, kept separate and alive would be nothing more than an ape, but when that same animal meets the memetic, infectious organism that is language... that is history, that is society, that's when a human being is born. We envision hive minds in our science fiction as something very alien to us, but isn't it that very nature that makes us alien to other living things? This whole interaction, this very thing you're experiencing right now where a completely seperate member of your species who you have no physical contact with and no knowledge of is creating abstract ideas in your own mind through the clicking of fingers to make symbols, phonemes and words, is immensely weird on the scale of a context that doesn't simply declare anything human normal by default. We can do this because we are connected, not by blood or skin, but by the shared infection of a common language, the grand web of information that is the most immortal part of each of us.What if advanced aliens havenât contacted us because weâre one of the last primitive planets in the universe and theyâre preserving us like we do the indigenous people? : space (https://www.reddit.com/r/space/comments/af6xvj/comment/edw3y3d)
That's not something that has to happen to life, that's not somehow the endpoint of evolution in any meaningful way, and humanity was nearly wiped off the face of the earth several times over before we got to that point. I wouldn't be surprised if billions of planets have developed life that is exactly like the life on earth, sans humanity, creatures that live and die without language and leave no records, no benefit of experience, no trace.
I don't think that's right. Civilizations might be incredibly rare but it's wrong to act like evolution doesn't converge in this direction. Almost every animal on Earth has complicated social interactions with others of the same species. From that point you just need enough intelligence for oral history to occur. It seems like humans are the first to reach this point, but that others have the capacity to reach it too with enough time.I've got a present for you from your friend SWORDF1SH:
Also if it is right, it's just a long and poetic way to say that society is a great filter.
The fermi paradox is really interesting to me because it just doesn't seem to have a solution given our current understanding of the world.

Someone on Reddit asked why astrology was ridiculous. Why's it ridiculous that the gravity from a star could have an impact on development?Wait is the supposed 'science' of astrology claimed to be about gravity of the stars? How does that make any sense? I thought it was just spiritual shame.
The gravity being tiny is the obvious answer.
The force of gravity between Earth and the closest star was bigger than I expected, but even still. It comes out to a tiny acceleration. Like less than a quadrillionth of the acceleration the Earth gives objects on the surface.
Basically even if astrology wasn't bunk, it'd still be stupidly useless that it'd basically be bunk again.
If the gravity from even the closest stars had an effect on development, so would the gravity of some large ships and buildings.
Haven't done any calculations, but I'd guess that the effect of most stars in astrology would be even less than the effect of small buildings.
Wait is the supposed 'science' of astrology claimed to be about gravity of the stars?It's the psuedoscience I've heard of it in the past. The redditor made a similar "why couldn't gravity do such and such".
How does that make any sense?I mean it doesn't make any sense so...
I thought it was just spiritual shame.I'm not sure how common the spiritual vs gravity explanations are.
Someone on Reddit asked why astrology was ridiculous. Why's it ridiculous that the gravity from a star could have an impact on development?Gravity is super weak compared to other forces but stars and space objects can be just so massive.

Something that most people don't get is when people are doing research on obvious questions.The worst is that no one wants to fund those uninteresting studies/experiments, especially ones that just set out to replicate old studies. Science only works if everything is checked.
Like questions that everyone thinks they know the answer to, just based off common sense or experiences.
One challenge is that common sense is often super wrong. The obvious, seemingly clearly correct view can actually be wrong.

Quora tends to have weird answers. That wouldn't work at all.Quora has a mix of answers from terrible to great.
It takes a lot of energy to launch stuff into space, the person is right that in situ resource utilization is important, but no one argues the resources should be used as is lol. Mine, refine, and manufacture all in space.But what if a space ship didn't have to go through an atmosphere?
A hollowed out asteroid would make a horrible ship. Way too heavy to move and way too fragile. A purpose built ship with heat shields would handle aerobraking so so so much better. The massive asteroid would have no way to control itself in the air and would need to plunge into the thicker lower atmosphere to really slow down. It'd be nearly impossible to end up in a desired orbit. Every real world spaceship needs to fly like a "plane" to control where they go. This video from the sixties shows how it worked with Apollo:
Interestingly enough, SpaceX's BFR was actually designed to enter the Martian atmosphere upside down.
This would allow the rocket to stay in the upper atmosphere longer and bleed off more speed before entering the thick lower atmosphere. Without having this control, the rocket would have too much velocity and would "bounce" off.
Quora has a mix of answers from terrible to great.Learning about spaceships and atmospheres has been a funny experience for me. First you think all the wings on spaceships in movies are cool cause sci fi, then you think all the wings are dumb cause physics, but then you think they're cool again cause rocket equation. In a super far future universe where rocket fuel works like car fuel alla epstein drive, dumb blocky spaceships make sense. They also make sense for generation ships or crafts with weak but highly efficient engines. For example a ship like this is freaking awesome.
But what if a space ship didn't have to go through an atmosphere?Spoiler for Hidden:

Of course the SI units of length is really not much better except that all the units of length are related by powers of 10. I don't mean to downplay the tremendous advantage of working in consistently in a given base, like base 10. I'm not knocking metric: it's great. But is it really so scientific and sensible to define a meter as:inches (http://math.ucr.edu/home/baez/inches.html)Quotethe distance that light emitted by a cesium 133 atom transitioning between the two hyperfine levels of its ground state will travel as it vibrates exactly 9,192,631,770 / 299,792,458 times?A careful study of where these numbers came from would lead us down some very tangled paths, just like the question why there are 63360 inches in a mile.

The universe is so strange.I've been thinking about that a lot as of late.
What came before? Is there anything outside of it? Is there a multiverse?
The universe is so opposite of everything we experience. Turtles all the way down (https://en.wikipedia.org/wiki/Turtles_all_the_way_down), almost starts to seem like it makes more sense.
I've been thinking about that a lot as of late.The past 4 months have been weird.
The universe is so incredibly young. 14 billion years is peanuts compared to the cosmic scale. It's terrifies me far more than the universe ending.

Movie science is great. They almost always take something the public has heard about and then apply it in a completely random way. Like how almost everything uses mega space shuttles in the future.
Science meme. 8)
I love when movies actually do the science though. Like you know the water planet in Interstellar? They really did the math to make 1 hour=7 years, but the movie explains it wrong.Yep, very familiar.
Yep, very familiar.I only learned about the interstellar fact recently. I knew about Kip Thorne, but I didn't realize he made the black hole spin as the primary way to induce time dilation.
Probably my favorite TV fact ever, is that for an episode of Futurama, the writer actually a math proof for the plotlines behind one of the episodes.
I've been laughing at my own dumb joke for 15 minutes. Maybe my sense of humor is broken, but I haven't felt this alive in a while.Still find it funny rofl
That's a funny mistake to make. The sun shield is probably the most well known element of the telescope at the moment.
Neil deGrasse Tyson makes a bad error about the JWST.
He claims here that JWST is orbiting at L2 in Earth's shadow and that it protects the instruments from the sun.
JWST is not orbiting at L2, it's orbiting around L2, and is in fact never in Earth's shadow.
I feel like I've been seeing a lot more Neil deGrasse Tyson making more bad takes lately.He's run out of things to say, so now his only options are repeats or things not worth saying.
I always find it a little interesting when people think they understand light.I don't understand what you mean with the mirror one. Like I think I actually do, but there can't be people that don't understand that right?
There are plenty of lighting conditions in real life that don't look the way most people would expect.
I think people really underestimate how much light bounces around and how much the color can be affected by these things.
If you look in an angle towards a mirror, you can see things that are not being shown to the mirror. If you hold your hand up to the mirror, you are able to see the back of your hand in the mirror.
I remember someone was using that as evidence for something because they were certain that it was impossible.
And some of these people, I think are reasonably knowledgeable.
I don't understand what you mean with the mirror one. Like I think I actually do, but there can't be people that don't understand that right?Maybe a better way to explain it.
On a similar note I think the same thing every time a movie has a character look at themselves in the mirror. Movies often cheat and in real life the person isn't looking at their reflection.
Maybe a better way to explain it.Here's another one I was just reminded of.
If you try to hide something from a mirror, it's usually not that hard to find an angle where you can see that thing.
Like if you're holding your phone in your hand, there are still quite a few angles of your phone where there isn't a direct line from your phone to the mirror.
And yes, there are people that don't seem to get that.
