>Yes. Because if you also pick an arbitrary starting point and then follow around the loop you'll end up at points you have already visited, thus you must have passed the end point.
Sounds like we're only disagreeing on what the word "end" means then and whether or not you can go beyond it.
If, in travelling in any direction, you arrive where you started after some fixed time interval, then the Universe must be finite because you could measure the distance that you travelled and therefore determine the Universe's "size". It could be that there are physical reasons why this is impossible to do in practice analogous to moving faster than c. We do have good reasons for thinking that the Universe is expanding so measuring the size of the Universe might be difficult.
It might also be difficult to come up with a measurement unit to describe the size of the Universe since all measurements of anything are relative.
My 3 dimensional head hurts.

Might be. 
There are two kinds of people in the world: those who can extrapolate from incomplete data.
There are only 10 types of people in the world, those who understand binary and those who don't.

You know I was just reading my last reply and it occurred to me that since there are no fixed points in space, how could you possibly determine when you had returned to your original position?
Blah.

Possibly not. In which case, what is beyond the edges of this non-infinite universe? More universes? If so, what demarcates the edges of this one and the edges of the others? Can they not all be part of a larger universe?

Perhaps more realistically or at least more philosophically pleasing, a finite universe could still be unbounded, for example if it is a 3-ball or 3-torus or something like that. That would mean that you could travel an infinite amount in any direction and never find "the edge" (since there is no edge) but you may find yourself returning to a place you've been before. The volume would be finite that way, but you don't have to worry about how space itself can even have an edge at all and what that might look like.
But it isn't really known whether it's finite or not in the first place. It seems to be flat and isotropic, if it actually is flat and isotropic then it is infinite. But it might not be exactly flat, it might be curved less than could be measured so far. Or it might not be isotropic, or both.

My theory: The universe is like an expanding balloon with everything that currently exists sitting on the surface. Heavy objects like black holes, stars, and planets sink into the surface warping space-time to create gravity. If you could travel at a rate faster than expansion, you would eventually come back around to the starting point. The interior of the balloon is the past.

Maybe "space" is infinite, but the big-ball-of-wobbly-stuff we call "the Universe" isn't?

IMO, the question cannot be answered because nothingness is still conceptually "the lack of something", so there is no "beyond," but that's similarly a null reference exception! But realistically, I suspect no one, even given an infinite amount of time, would ever be able to know, because the universe will end before we can reach even the point where light from the edge could reach us.
Now, that's another conundrum -- if the universe ends in time, what does it end as?

Thats, just like Drakes equation, full of assumptions. And like Drake, you are being rather optimistic.
We already know that there is no sign of intelligent life in the observable universe. So, we have to consider the possibility that we are living on the first planet with some form of life.

No, not quite.
The universe can be infinite without having infinite mass or infinite number of particles.
"infinite" just means it doesn't stop. Take a number and divide it by 2. Keep going. Forever. That's infinite.

How can something run into infinite if it had a beginning. What i want to say is, that the universe is bound to the subject that made it possible. So for example once the Sustainer disposes it, it no longer can be infinite it will be set to absolute nothing. Only in theoretical Math values can have a beginning and be infinite, but again, even so, when the environment is disposed, then that loop will also crash, because there will be no spectator and no physics. Do you not realize that the world is programmed just as you program something, only the Creator of everything is exactly knowing what He is doing, He is most-excellent at it. Do you expect yourself a programer and your apps intelligent design, while the universe and "life" came from Nothing?

It just doesn't matter. We are sitting on one of know one even has a really good guess how many planets. There's no way, from here, to know if the Universe is or isn't infinite. I just don't care.

There was one like this that I loved...
On any planet in which intelligent life is found, the probability that they will explain their existence on a God is 1...
To the original post, even if infinite, it may be the case that intelligence is only on one planet at a time! And I can't wait for Earths turn!
