space is infinite? observable universe not (exists furthest line between two bodies that is less than infinty)? what about the rest of space? universe is there and after that nothing? exist "edge" of universe?

The reason you can't travel that far is because it is a part of your past; you can't interact with that - only watch it dimly fade away.

universe is limited. What does the universe exist within? Whatever it is, it is limited.

yea, you just go around and end up in the same place. space travel is pointless.

yea, you just make up pointless statements to go around and end up in the same place. discussion is pointless.
This is like arguing that because the surface of the Earth is finite, if you travel far enough you have to fall off the edge eventually. I'd phrase that like >>1 but I don't think I can make my English bad enough.

You could also let someone competent in the field be the judge instead.
Quit being stupiddd, the universe just ceases, it doesn't go on forever - that is how we define BOUNDARIES [SOMETHING YOUR WITS NEED MR. CAT] because it is non-nonsensical to say otherwise.

so, if it ends, what is on the other side of that boundary, kind sir?
There would have to be an interaction of energy that is causing the boundary to occur...so, what is it?

how can something that is everything have a definable edge or an absolute definable size?

For all intents and purposes it doesn't have a definite size or "edge." A more exciting question to ask is how different energy levels can cause the universe to behave in different ways geometrically. My bet is on geometrically flat, meaning light does not wrap around on itself.
I find the definition of the word "universe" a bit stupid.
"The Universe comprises the totality of everything that exists" - Webster's New World College Dictionary.
Yet we claim to know its size and age, that's rediculess. Our planet is in a solarsystem, which is in a galazy wich is in the (or an) "universe", and who's to say it too isn't in a system of universes? Maybe far beyond the edge of our so called universe, there are others like it.

there's no such thing as intelligence. Everything man knows, he knows from what he can understand and create for himself TO understand. It's all made up pseudo-intellectual drivel...mine's just another shade on the color wheel. And, at least I know better.
I wouldn't say our universe is infinitely large, I would speculate that our universe is infinitely small.

if the universe has an edge, why cant we see it? Light shouldve reached us by now and if the universe expanded it certainly did not expand at the speed of light, so why can we not see the edge?

thats called a galaxy smart one, all the galaxies exist within our universe
