- s1artibartfast 6y agoI would take that bet. The observable universe is estimated to have 10^21 stars and the actual universe is infinite.
- warent 6y agoI'm not sure what you mean by the "actual universe" but there's no proof that space is infinite. Unfathomably vast yes, but still finite.
- internet_user 6y agowhat's the proof it's finite?
- warent 6y agoOur senses are finite; we cannot directly know infinity through them. Because of that, I think the burden of proof is on the claim that it is infinite.
- mnjn 6y agoIsn't space itself continuously expanding?
- mathdev 6y agoExpansion of space doesn’t preclude the universe being infinite.
- s1artibartfast 6y agoby actual universe, I meant total universe ( opposed to the observable universe). All of the evidence we have collected so far suggests that the universe is flat and infinite. While some finite universes could be proven, so far we have not.
- lokedhs 6y agoThe size of the actual universe is irrelevant for this discussion since anything outside the observable universe does not have any casual connection to us. But of course you are right about the absolutely staggering number of stars in the observable universe.
- s1artibartfast 6y ago>The size of the actual universe is irrelevant for this discussion since anything outside the observable universe does not have any casual connection to us. 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.
- _annum 6y agoCan you unpack your reasoning here? The likelihood of civilizations occurring/existing in parallel leads me to a similar conclusion.
- Damorian 6y agoNot OP, but I fully agree with them. Incoming ballpark figures I and hand waving. If, today, with our current technology, we decided to explore/colonize every star and planet in our galaxy, launching 3 ships per day that travel at single digits percent of c, we could investigate every planet in our galaxy in about a billion years. That's pretty much worse case technological scenario, because at some point in the next thousand or million years we'll have even more incredible technology to build more and fly faster. Probes that can constantly accelerate at 1g will reach other galaxies on the order of millions of years. If they self replicate, or have pioneers that can rebuild civilization on the order of a few thousand years and continue exploring, we're still within that 1 billion year limit to colonize at worst the entire galaxy, and realistically the entire universe. Earth has been around for 5 billion years, and the greater universe for 15. Humans have only existed for 10,000 years. ET should have been here long before we even came into existence.
- solidasparagus 6y agoWe only have a few thousand years of reliable history and in many places, far less than that. It's perfectly reasonable in your scenario that ET was here long before we were, missed us by a couple of million years and left. If you look at the history of human exploration, discovering new lands has not led to immediate settling or the establishment of long-term relationships with the locals.
- StreamBright 6y agoAssuming they do not have a prime directive.
- s1artibartfast 6y agoIf the universe is infinite and life is possible ( as we know it to be), then life will occur an infinite number of times. If we just look at the observable universe, number of stars, number of planets, and habitats we see even in our own solar system, there are a lot of shots on goal.
- ekianjo 6y agoWhy take a bet on something that can never be verified?
- StreamBright 6y agoCan you point out anything that exists only exactly once in the universe?

- nix23 6y agoFirst tell me what intelligent means....then we can make that bet ;)
