d) cross the boundary and cease to exist

e) none of the above

Hi Steve, welcome to the TOE Quest forum.

A good question at the start of baseball season.

I guess I would pick e) none of the above. I vision right outside our universe is the void, which becomes part of the space/time continuum as soon as something enters it. Purely a guess mind you, since I've never hit, or threw, a baseball that far.

In other words if the baseball is going faster than the expansion rate, that would become the new expansion rate for our universe, since it would be part of our universe.

Best to you,

Pat
