Isn't that an unknowable? We literally have no means of deriving information about the universe beyond our lightcone. And that's not even touching on what qualifies as "part of" the universe, depending on which definition of "universe" you are using.
It's an undefined question, I feel.
It's not completely so - it might become apparent that the universe was finite, and that would answer the question. But determining that it is infinite is different - after any finite amount of time, you can only see a finite part of any universe. So you will never know for sure.
Often, there are questions you want to know the answers to. You want other people's opinions, because knowing the answer isn't worth the time you'd have to spend to find it, or you're unsure whether your answer is right.
LW seems like a good place to ask these questions because the people here are pretty rational. So, in this thread: You post a top-level comment with some question. Other people reply to your comment with their answers. You upvote answers that you agree with and questions whose answers you'd like to know.
A few (mostly obvious) guidelines:
For questions:
For answers:
This thread is primarily for getting the hivemind's opinions on things, not for debating probabilities of propositions. Debating is also okay, though, especially since it will help question-posters to make up their minds.
Don't be too squeamish about breaking the question-answer format.
This is a followup to my comment in the open thread.
