If our universe is flat, how do we see other objects in space 360 degrees around us everywhere we look?

Question

Shouldn’t we only be able to see other objects by looking out from the “sides” of our planet in line with the orientation of the flat universe?

Answer 1

Flat and 2D are different. If the universe was 2D then yeah we could only look out in a circle instead of a sphere. When people say the universe is flat they mean it’s not curved. For example if the universe was curved like a sphere if you went far enough in one direction you would end up back where you started. That doesn’t happen so we say the universe is flat.
