It could be a micron larger than our lightcone. It could be a mile. Or it could be infinite.
I don't know precisely how likely these three options are, but infinite seems astronomically more likely that any arbitrary amount.
Given assumptions that seem natural now. I don't actually disagree with those assumptions. But those assumptions are, in fact, assumptions. (Recall the bizarre topology example that permits for negative space beyond our lightcone.)
Given, furthermore, what the original question was -- P(Universe-is-Infinite) -- the question of whether there's even a 'something' out beyond the lightcone remains even-more-relevant.
And as I originally, I believe, said -- the low confidence interval necessary to properly express a Bayesian probability prediction in my opinion ...
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.
