We came from comets! Confirmed

Math!  

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.  

Infinity is weird.

To infinity...and beyond!

Good ol' Discrete Math.  I mean... fudge Discrete Math.  dang "proofs"

I think psychologically infinity is weird.  
Not just the fact that it's counter intuitive from everything we know from numbers.  
But it's almost like it's usage has made it seem small.  

"Oh yeah, well I have an infinite number of tacos!"

It's thrown around almost like the number 6, and yet's its so gigantically bigger than anything we can imagine.  
It's well, infinite.  But reading about Graham's number, it's like this is CRAZY! But really it's like well in the "eyes of infinity, that number is practically 0."  And yet that number is stupidly huge.  So unimaginably stupidly huge.  G1 is already stupidly huge.

Hmmmm, a Martian fossil (if this is on Mars)?

It's just a cool rock.

[Mmm_fish_tacos]

That's no rock.

Also I guess they didn't want to point out the dragon/snake head?
