I don't know about the edge of the universe, but the only thing
currently at the edge of the earth is atmosphere. Where the
atmosphere ends is where the earth's edge is. If you ask what the
edge of a box is, you find that it is the outer extremity. This is
also true of a circle, or a shpere. The earth is a sphere. Thus the
earth DOES have an edge. The universe, if infinite, has no edge,
because it would have no shape. If the universe does have an end,
then what is at that edge is unknown.
Only those who don't know that they're doing it, can do the impossible.
