What is there beyond sky,beyond,space,beyond universe...?

Answer 1

Outside the universe there is nothing. Complete and total non-existance which is infinite if only because there's likewise no way to measure it. It's not that we "can't go fast enough" to get outside the universe... there's no way we could exist outside the universe.

Think of it this way, the region outside the universe is non-existance. There is no time, length, width, or height. The laws of physics do not apply at all, because beyond the edge of the universe there is no other physical body constrained by our laws.

There may be other universes out there, but that can't be known, because even light can't exist outside our universe... and even if there are other universes, they might not follow the same laws as us. Maybe their gravity is reversed and everything repels, bouncing around like a bad game of universal pinball.

We can't even determine how far away another universe might be, since there's no distance in existance to describe any measurement whatsoever. Another universe might as well be right on top of us AND fifty billion light years away at the same time.

Answer 2

Since we cannot move fast enough to surpass the 'boundary' of the Universe, we can't knoq what's out there (at least not with the senses we were given).

Answer 3

The universe is just a dark sphere and insid it is us planets, so teh universe is a giant planet itself and so on.

Answer 4

infinity
