If space is finite, what is outside the end of the universe? Or for that matter, what is the limit on the microscopic scale?
If there are an infinite number of worlds, then there must also be an infinite number of habitable worlds. We know that there is at least one habitable world (Earth) and that there are other worlds with the right conditions. If there are an infinite number of planets, then there must also be an infinite number of habitable planets (infinity minus one).
Space doesn't have to be finite for the matter in space to be finite. I'm in a room that measures about 25x10x30 feet. Does that mean that there are as many ants that take up that space? No. There are probably only about 10 ants.
You guys are funny, the only time infinity is higher level math is in logics, astrophysics, and a few algorithmic math problems.
Other than that it is almost always a philosophical idea. No Higher level math being used, just abstract thought.

Ok, don't believe me? Heres a poorly put together example:
Going from what the OP said, logically there could be an infinite number of worlds in the universe. Ok, I make the claim, but can I prove it? Well, unless I am around for infinity, I can't prove anything. How can I know for sure that after I claim there is an infinite number of worlds in the universe, that I won't be proven wrong afterwords? What I'm saying, is that you can't ever make the claim that something is inifinite, since it could change right after you make the claim. Instead we have to assume that it will follow this pattern even after we make the claim.
While we're on the subject of random stuff, heres one for you: Life is theoretical.
By that argument nothing can be proven. I mean I can prove that gravity always pulls to the center of mass, but how do I know that it still does now...how about now....and now...
To prove anything we have to assume that the laws of the universe are fairly static. If you will not accept that then you fall into the catagory of a Nihilist and we have nothing more to talk about.

There was a very good article a couple years ago about orders of reality. Without going into detail, it MAY be that the rate of expansion during inflation was infinite. If so, the universe is infinite.
Suppose this to be true. Can we see it all? Well no, because the volume of space we can see is finite, because light can only have traveled so far since the Big Bang.
Now given a hypothesis, what is the consequence of it?
Well, any given volume of causally space can house a finite number of particles. You could have between zero and all space filled with protons. We will call each volume a "universe" from the perspective of an observer.
So what? Well you could have a universe packed full of eleventy zillion particles (the exact number they used I cannot recall)and another of the same number less one, and another less two and so on, until you have zero. Now there are a limited number of places these particles of whatever number could exist. Like Legos a finite number produces a finite number of "structures" If you have 10 legos, you can only make so much. Finite permutations. Likewise, there are finite (although immensely large) numbers of possible spacial arrangements of these particles. Thing is that who cares? What is the largest number compared to infinity? It's infinitely small.
The bottom line is that at about every 10^180 lightyears, our universe MUST repeat. That's when the possibilities run out. Of course since there would be an infinite number of such volumes, there MUST be an infinite numbers of identical universes. Not only that, if you almost dropped you plate the other night, there must be an infinite number where you did and when you didnt. All possibilities in fact exist.
Weird eh?

XD.
About the whole "You're an idiot OP" comments, I didn't make it up. My friend sent it to me and I thought it would be amusing..
