How far out does space go? I can't imagine it coming to an end. However if it did come to an end, what is stopping you getting through it and what is behind that?

All the way...
If you reach the end, you'll find yourself back at the beginning.
Strange, isn't it?

Don't even try to think of what comes after the end of space. It will drive you crazy!
What we do know is that space is as big as our universe (not necessarily infinite) and has been expanding at an ever-increasing rate since the Big Bang some 13 billion years ago.
What is outside our universe, if anything, we can only speculate at this time.

Our space-time is finite in this universe, but expanding. They believe there are actually many more dimensions than the 3 space and 1 time that we experience and the birth of our universe was the breaking out of our 4 space-time dimensions from 10 or 11 higher dimensions.
At present, unless there is a lot more dark matter (or 'something', possibly from a higher dimension that we cannot see - but gravity can penetrate all of the dimensions), it appears that our universe will eventually 'evaporate'.

Our Universe (space) goes out about 15 billion light years. Its not likely to end as such but it would seem that eventually, hundreds of billions of years from now, it will stagnate and will reach an even temperature all over.
It is conceived that our Universe is expanding into nothingness. A difficult concept.

our observable universe is a finite size, equal to the age of the universe in light years.
however we cant know how big the real universe is, since we cant see beyond the observable universe.
and to say we'll come back where we started if we reach the end of the universe only applies to a closed spacial geometry(like a circle, sphere, etc), and evidence has shown that its unlikely to be the case.

well the visible universe is about 14 billion lightyears across if im correct, but thats just the visible we think theres more.
and the first person is right. the universe is thought to be 4 dimensional, so one you reach the end your right back when you started. dont picture it like you just teleport back to the beginning, cuz u dont, think of it as the unvierse wrapping around and connecting to itself. it seems weird but after you know enough about the universe its really the only logical answer.

The universe is, for all we know, is infinite.
