I was just wondering if we have any proof at all whether the universe is finite or not. I have heard that it is indeed expanding - which could mean that it is possibly finite... is this true? or what is anyone's opinion?

Our universe is at least 93 billion light-years across, and still expanding. Since we are inside of it it is likely impossible for us to prove it is finite even if it is. On the other hand, the continuing expansion doesn't seem to be stopping anytime soon, which speaks to a possibly infinite universe.
