How big is the universe?
Do you think the universe is infinite? Do you believe in a multiverse?

Feel free to reply to any comment by clicking the "Reply" button.Seems pretty common knowledge to me, but the universe is expanding and will one day collapse on itself ending everything as we know it. People speculate another big bang will occur after that and repeat the cycle.

As it currently.stands the expansion is still accellerating. It could expand forever, and eventually just be a void in which the only things are black holes evaporating via Hawking radiation.
That way we get incarnated!!!!
@CliffordStone No, nope , nope, nope. That eliminates any type of causation.
@buzz13 I'm not sure what you mean.
No, the current thinking is the expansion of the Universe is accelerating. They explain this with "Dark Energy".
One Universe, infinite and eternal.

So something out of nothing, not even energy?
@buzz13 The matter that is here has always been here, and always changing
Physics was leaning to infinite multiverse last time I checked. Could be different, but the math is working out to nicely for it not to be something.

Yeah, I was just curious if there was any contention on the subject. I thought of the multiverse when I was 14 and nearly slipped in the shower, thinking "what if I'd slipped and died? What if I DID slip and die?" I only later found out I wasn't even close to the first to imagine multiple timelines in which all possible outcomes do occur.
The pendulum is starting to swing back towards an oscillating universe.
@buzz13 Really?! even with Hawking's last collab on the subject?
