I just watched a program on documentary channel, where this guy who hardly knew anything bout maths was gettin taught bout prime numbers and other such stuff..
They got to a question where the teacher was like "If you get this question right, you'll get $1million bux" I thought that was a simple question to answer...
Well I'll tell you their answer first, they said it was like a 4D donut. (I won't bother explaining what a 4D donut is like but I guess a lot of you have heard or something like it..)
My simple answer would of been endless for a universe, or a near sphere shape for the end of the material universe.
I don't see how they could come up with anything else, in the donut you could reach the "end" of the universe and if you pass that point you'll end up on the other side of the universe and you could pretty much travel till you reach the point where you left off on your journey...
Where on mine you could reach the end of the material universe which is most likely material which has been thrown further out into space by a recent supernova or even further if your counting how far light as traveled since the first star was born (which would still be traveling today.. at the speed of light).
If you could pass that then you'll reach a part of the universe which has nothing and will go on forever in deep darkness.
I think I should of gotten that million dollars.. What are your thoughts?
