WarpDrive built. NASA mystified by device.

[Legend]

Haha no. I just wanted to have a fun title for gullible people.


What's really happened is NASA is trying to understand how a device called the EmDrive produces thrust. A leading theory is that it's warping space, but too early to know if it's actually the case or not. Heck it could just be flat out experimental error. If it ends up being real, consider yourself informed. http://forum.nasaspaceflight.com/index.php?topic=36313.1860

With this type of technology,  it would be possible to predict when locally past events are going to be observable from the point of view of the Earth (or any other point that the light from such events had not yet reached). For example, a ship 1 light-day out from the Earth in the right place could witness a supernova before the Earth does and then be able to return to the Earth almost instantly and tell astronomers about the incoming light wave so that they could prepare to observe it.

Lol. I wanted to ask about this, imagine if you could catch earth's light and have a computer translate that light, you could have a Window into the past, maybe we could figure out what really happened to the dinosaurs

Hehe you can tell he's not an expert.


General/Special relativity, no backwards time travel, and faster than light travel. You can only have two of them be true, just based off how the math works. Experimental evidence very strongly supports relativity, so that means if ftl travel is possible then so is backwards time travel. So if this warp drive could go faster than the speed of light(no one expects it to) then you wouldn't need to mess with catching light way off in space. You'd have the ability to just go back in time and see for yourself. Plus we already can get lucky and do what he's talking about. Light moves slower in high gravity fields of space, so on the surface of earth we can observe astronomical events happening twice.

With your dinosaur thing, yeah it's possible without ftl travel and would be really cool! We'd just need some black hole or gravity anomaly to act as a mirror, showing what Earth looked like millions of years ago. The biggest hurdle would be getting strong enough telescopes.

So here's a super simple version.

Quantum mechanics is strange. Everything is a probability. So there is a probability that matter will just create itself from nothing.

Turns out this is actually pretty common. Empty space is filled with matter popping into existence and then disappearing just as fast.


So this device is using that matter in the same way a plane's propeller uses air.

Alternatively, It's MAGIC!

MAGIC IS REAL!

I CAN FLY!



Apparently magic isn't real.

Well my image was just a joke :p

Anyways, matter disappearing..? Disappearing to where though? Alternate Reality? (Not joking - I actually am interested and believe in multiverse theory).

I knew you were joking, but I never ignore an opportunity to talk science.

The matter is converted to energy.

Oh

Still - this could lead to advancement in technology and that's always a good thing especially in this case.

It would be a reactionless drive, which would revolutionize space travel. Right now when we shoot off a probe, it just xenos gas and electricity to move. Once the xenon is used up, it's dead. Or when launching a rocket we use tons and tons of heavy liquid fuel. For example a fully loaded space shuttle weighed just above 200,000 pounds, yet it took a 4,200,000 pound rocket to get it to space.

If this Q-Thruster works like the tests show, then rockets will be able to fly on nothing but electricity. Stick a nuclear reactor on a space ship and that thing could to Mars and back for relatively extremely cheap. Or use solar panels on a space probe and it'd be able to fly from planet to planet, moon to moon, gathering incredible amounts of science. It could even come back to orbit around Earth and drop off physical samples.

It'd be incredible.

This is what I am hoping for.

is this old?

Last year, NASA's advanced propulsion research wing made headlines by announcing the successful test of a physics-defying electromagnetic drive, or EM drive. Now, this futuristic engine, which could in theory propel objects to near-relativistic speeds, has been shown to work inside a space-like vacuum.

NASA Eagleworks made the announcement quite unassumingly via NASASpaceFlight.com. There's also a major discussion going on about the engine and the physics that drives it at the site's forum.

Yeah this article: http://www.nasaspaceflight.com/2015/04/evaluating-nasas-futuristic-em-drive/ was released two days ago as basically a summary of where eveything's currently.

It's still all the same stuff, just a nice way to present it.
