Euler wrote Space is regarded by some as infinite. The truth is that we cannot, and probably never will, know how big the Universe actually is, because we cannot see the edge of the Universe, not because of how far away it is, but due to the fact that shortly after the Big Bang, the Universe expanded at a faster rate than the speed of light, and so the light from some of the further away areas in the Universe has simply not reached us yet.

However if the Universe was to stop expanding, and would so become a finite region, there would still be no end. Think of it like trying to get to the edge of the Earth, you cannot do it, after a long time, you will just end up in the place you started. The same goes for the Universe, due to the fact that it is made of a 4-Dimensional fabric (if Einstein is in fact right), and due to the overall shape of the Universe, as some believe it is almost donut shaped!

Well space is not infinite in size simply from the fact that if it were to be infinitely large it must have been expanding for an infinite period of time or at an infinite rate- No finite numbers can multiply together to make a number with an infinite magnitude (disregarding an infinite series as this isn't really what's being referred to here) this is simply distance = speed x time, so two variables. The universe is travelling faster than the speed of light, you're right with that, however not at an infinite rate:

1. The velocity of such expansion has in fact been measured from the red shifts of light from observable galaxy's etc and so is a measurable quantity and not "infinite".

2. The universe has not been expanding for an infinite period of time because there was a singular point of which the expansion of the universe began and such time frame to our present is not infinite (13.77 billion years).

So, evidently from this the universe is not infinitely large though this is considering a singular universe; I am disregarding multiverses etc. If you are lenient towards string theory then yes the universe(s) may in fact be infinitely large.

I see I didn't explain what I meant clear enough. The Universe is not infinite. However, the idea that the Universe is infinite comes from the idea that the Universe will expand forever, at a rate faster than that we can keep up with, i.e faster than the speed of light. And therefore is regarded as to be infinite, even though still be finite, as the Universe will never be a measurable size, and so can therefore be modeled as infinite, as it is expanding at a faster rate than we can see.

I wasn't arguing against your points made but just saying how it can't (perhaps) possibly be considering as "infinite". Though we can calculate the size of the universe as we do know its rate of expansion and how long it has been expanding for, although maybe not accurately there have many approximations of which are perfectly valid. I admit the fact that we don't "know" the universe is not infinitely large but, we can make some indirect assumptions of which are more heavily backed than otherwise. Though you're right in that we can't geometrically measure or even fathom the size of the universe, I agree with you there.

(Still disregarding string theory)

The problem with answering this question is that can't. Space doesn't just 'end' it's always expanding, when you were born you literally moved the entire universe away from you, same goes for every single bit of mass that is created.

space is growing and expanding all the time mate.

no one really knows.. but i say.. more space

"i think it's just more space"

that sounds like something karl pilkington would say.

The universe is round; just like planets. Therefore, you will end up going in circles.

its wierd trying to thank about the end of space

Well I like to think of the Big Bang Theory and if it's true at the end could be the crust debris of whatever blew up.
