The question is, Does the universe (the conglomeration of all energy in existence) logically require an escape velocity? My reasoning is thus. If the universe is at least partially composed of massive objects that exert gravitational pull, wouldn't the sum of every massive object in the universe and it's corresponding gravity factor into some finite (although perhaps unknowable) force from which we could calculate a theoretical escape velocity - what we'd escape into, I'm not sure ? If the answer turns out to be beyond the speed of light, wouldn't that mean that we are in some type of a black hole? This hardly seems logical but I can't locate the break. Thanks.
