If space is curved, it would never end. If we start from one point in any direction, finally we will reach same point in space. Do you means this infinite? But, I don't think so! It is just unbounded space!
Please note that space-time is also curved! So, we will reach in same point but different time. As space is moving forward along with time, the only way we can go back to past is that we should travel in opposite direction of space movement.
How to travel in opposite direction? According to Einstein, travel faster than light speed!
So, is time infinite? No, movement of space will finally go back to singular point (as what we see in BIG BANG).
So, Nothing is infinite in space-time!

There are types of infinity, similar to what you can experience on earth. You can go in one direction indefinitely without ever coming to an end, including no sign at the end. Space very well may duplicate that in 3 dimensions, at opposed to the 2 dimensions experienced on earth's surface. Thus you could experience an infinite space, in a finite universe.

The question doesn't really make sense. Everything we can detect or interact with is in our universe and outside of that is simply "undefined". As the universe expands outwards, so is space expanded and created. On the other edge of the boundary is time and space not yet created, until our universe overtakes more space and thus brings it into existence!
It's like asking what happened before the Big Bang - there was no before, it's null. Time began at the moment of the Big Bang and so its existence cannot be spoken of previous to that point, it's undefined!!

Space as we know it, is infinite, as the universe is apparently still expanding and not stopping or slowing down, not just yet anyway...the universe however does appear to "end", at the far reaches of the visible universe. The very edge of the universe is considered to be where the farthest detectable light or energy source is found...beyond that point is considered the end of the known universe, however, it is possible more galaxies and stars are there, they just haven't been detected yet...however, if they are never detected that could signal the very edge of known space, whats beyond that edge is best left up to the cosmetologists, but i will guess that it is an empty vacuum......but postulating beyond that, could more universes exist beyond our known universe edge? and what about big bangs, could there be more than one of those, but in other universes, beyond our own?

This is the most difficult question to answer. We human beings can't even imagine where space ends. If we think that there is a wall like structure or end point, then what is beyond that wall. There has to something beyond end point.

Who cares if is infinite or not, it's huuuggeee from our point of view.
Space is rounded a somekind of circle.
We are "seeing" a small chapter on the life of space, it is in the middle of a huge transition and we are witness of a very tiny little part of it.
Similar is with clouds, it seems that they don't move, but they do, we all know that, but we do not take the time to "see" them moving, in space is the same process but much much larger.
We don't live enough to see a substantial part of it.

I hate to answer a question with a question, but: If nothing is infinite, when will time end? Time and space are one, never ending and ever expanding, a looped line to itself.

If walking around the moon or earth(if you could walk on water) where would it end? Is the land infinite? After all you can walk for ever and never find an end. The universe is no different.

Certainly, "nothing" can be infinite. Zero times anything is still zero.
Infinite "nothing" isn't difficult to imagine or visualize - it's still "nothing."
Ever consider the possibility that space without any objects in it is indeed just "nothing?"
It's only the distance between objects that give it any meaning.
Could be that as our universe expands into "nothing", it is literally creating space.

Ever see The Matrix? That scene where Neo is in the train station and he tries to run out of it only to come back in on the other side, over and over again.
That's Space.
