There's a theory that: The Universe is expanding because objects in universe is moving away from each others.
Do you think the Universe doesn't have a limit, or is there anything lies outside it?

it's the same as asking whether time has limit....

how do you define limit?

base on what standards do you decide if something has limit?

"The most incomprehensible thing about the universe is that it is comprehensible."

Yes, that's the theory of Einstein, I've found a movie about it.

how about basing it on the beginning concept of something, let's say, time.

the start of time marks its very limit, and everything that exists must have a beginning.


a = b, b = c => a = c, right?? :D:D


that is a whole lot of fallible logic, but the idea of challenging some people is just very appealing..
