Is it flat, closed or open? What evidence is there to support this choice?

Not the op. What happens if you reach the end of space (i.e., the border). What would it look like and what would happen if you crossed said border.
Is space like a sphere? And by that I mean, is it like Earth. Could you pop out one end of space and end up on the other? (And no, I'm not referring to wormhole travel.)
