Reply to comment by urzu_seven in ELI5: How is that space is “flat” yet we are able to look around the universe (up, down, left, right, etc.,) as if it were not flat? by nhabz

I'm trying to keep it simple. But plz do explain. Without explaining like your talking to a scientist who knows alot of the concepts of space/time.

Edit.

But we both know space isn't flat.

Spacetime is not flat. It can't be: Einstein's general theory of relativity says that matter and energy curve spacetime, and there are enough matter and energy lying around to provide for curvature.
