Is it possible to work out the escape velocity of the universe?
The visible universe is assumed to be sphere shaped with a diameter of about about 93 billion light-years. However, its size could be distorted. Using the escape velocity equation you could work out the speed needed to escape the universe. Whether this would rip the fabric of speed and time, who knows? However, the problem is purely hypothetical as the universe might not end, it could loop back in onself. Equally though the universe is still expanding, and the big question is what is it expanding into? If it stops expanding and starts contracting what will it leave behind? Where would the universe end and just space begin? If you could find that out then perhaps you could leave the universe, go into x space then pop back again….
