You're right, that was one of the erroneous assumptions I made. The problem with that is that there are an infinite number of permutations of possible universes. Even if only a small fraction of them are habitable, and a small fraction of those are conducive to intelligent life, we still have the multiplying by infinity issue. I don't know how valid using infinity in an equation is though, because when there are two infinities it breaks down. For example, if they're are an infinite amount of dogs in New York, and 10% of dogs are terriers, technically the probability of the next dog you see being a terrier is equal to that of any other dog. That again simply doesn't make sense to me
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.
