But of course you are right about the absolutely staggering number of stars in the observable universe.

I don't see how causality plays into the question at hand. The parent post didn't bet that we could interact with alien life, but if it exists at all. If it can be demonstrated that the actual universe is infinite, it will follow that alien live exist, independent of if we can interact with it.
- turboturbo 6y agoThis is logically incorrect. The universe may well be infinite, but that doesn’t imply it must harbour life
- dTal 6y agoI believe this would be correct if there were no examples of life already extant - but the fact that we exist shows that the probability of life and civilization arising is strictly greater than 0. Given an infinite universe with a flat probability distribution (i.e. there's nothing particularly special about our little corner), any >0 probability will occur an infinite number of times. I highly doubt the actual universe is really infinite, however. Incomprehensibly big, yes.
- Kiro 6y agoNot enough proof to win the bet, so right now you're losing.
- s1artibartfast 6y agoRight now, nobody has proof. While aliens can be discovered at a future date, you can never prove that they don’t exist. It is a very safe bet because they can not prove a negative.
