>>11763064So first off, I'm not a physicist, so anyone may want to correct me, but by bucket or baseball, I just mean that space is finite, or was at some point. You can't measure "space", but you can measure stuff like mass or momentum of the objects in it (assuming you "set" some sort of reference frame). If the universe "exploded" from a point, then it would be likely that galaxies could have at one time, been spinning around some sort of center, and thus now they spin in the same direction.
By it's difficult to think of a boundary I mean that although at one point, the "universe" could have been the size of a baseball, you still could not define a boundary because any point "close" the edge would be expanding at the speed of light, so you could still travel in all directions equally (assuming you could not travel faster then light), also you could pick another point even "closer" to the edge with the same properties. Also I haven't studied much Topology either, but I think that would be called compact without boundary just fyi. I'm not saying the part about boundaries is true or anything, I just saying that it make the problem more abstract then just a simple spinning baseball analogy.
