The real question is, who cares? The way I see it, there are three possibilities:

1. It's finite. No matter what happens, we'll eventually run out of resources down the road in billions of billions of years after we mined the whole universe and extracted all the energy we could. Entropy's a bitch. We go extinct.

2. It's infinite, and matter was created by something like the big bang. There's a limited amount of matter in the universe. Same thing as in 1. We go extinct.

3. It's infinite, and matter was created by an infinite amount of "big bang like" phenomenas, perhaps even at different times. There might be infinite matter and energy. However, if matter from another "big bang" collides with that from ours, we're likely done for. Statistically speaking, we go extinct.

See? In the end, we're all dead, so it's not like questions such as "Is the universe finite?" matter.

Actually, I do, which is essentially why I've decided to study physics and aim for graduate work. Somehow I didn't really feel like giving a serious answer in a thread started by a Uranus joke. Not to mention cosmology is hardly my favorite part of physics, nor the one I'm most knowledgeable about.

It might also have something to do with writing the post around 1AM after a bit of drinking.

There's nowhere I can't reach.
