What Is The Shape of Space?

YouTube: This video is about the local and global geometry and curvature of space and spacetime, aka, is space flat? Negatively curved? Positively curved? etc.

The ultimate tautology - why is the universe exactly the way we need it to be to let us survive (temporarily) - if it was not we would not be here to ask. Obviously you can switch to asking how did it get to be that way and there is a lot of room for fun in that department.

Aquarium fish dont question the odds of having water in their aquarium. It is either there or it is not. Also our aquarium is really small right now and we are hardly trying to get out.

jokingly says...

If space is flat the earth MUST BE flat. *promote.
