We had a discussion about the finitude of the universe in the science forum quite some time ago. As I recall, I have heard it floated as an open question whether the universe is infinite or not. In my support of how this may be possible, I found the following webpage:

Interesting. In any case, it seems an odd speculation, as for there to be an infinite universe, then we would have to suppose matter that we have never had contact with and never could have contact with, which is a hard to justify assumption. Even the gravity issue leads to some problems, as let's just say that we have this situation:
A----------------------------B
Where both A and B are infinite masses. If you are a micrometer closer to A than to B, then you would be pulled towards the center of A with an infinite level of force according to classical gravitational theory. Thus... this seems problematic if we have a distribution of mass, I mean, I don't know how to model this, but it still seems problematic. I guess, I cannot think about a problem with infinite masses well enough to feel comfortable with my math, because there is an issue of not being able to even conceive of point-masses, but yeah.... I would really not trust such a notion.
