If you got to the edge of the universe would you hit a "wall" since technically there is nowhere for mass to exist beyond that point?
But let's say for the sake of argument that there is an edge. What would happen if you reached it?
Hmm, well one possibility is that you wouldn't be able to go any further because there would be no more space to occupy. Another possibility is that the laws of physics as we know them would break down and anything could happen.
