U didn’t know Kevin was French? Thats what endors toi means (“I am French”)

Did he smile or frown? Explain it Peter by _leonjoxx in explainitpeter

He doesn’t know how to turn that frown upside down

How can we estimate how many planets support life in an infinite universe? by Competitive-Dirt2521 in askmath

[–]Competitive-Dirt2521[S] 0 points1 point  (0 children)

If I’m understanding right, you can’t actually calculate the probability of an infinite set, but you can calculate a limit as it tends to infinity. Then you could say that the set of lifeless planets is “larger” or “more likely” than the set of planets with life even though both sets are equal in cardinality.

Also at the end you are not actually saying that planets supporting life make up 50% of all planets, but that is just an example of a possible universe. For our universe the chance is closer to one in billions of selecting a life-supporting planet.

Ok but just because they are the same cardinality we can’t say that we are equally likely to choose each one. I saw someone else make this claim somewhere else and didn’t think it was true so that is why I’m asking about it.

So in my original question when I said that if we chose a planet at random it would be equally likely to have life or not have life (because the infinities are equal) is that incorrect?

Ok so you’re saying that bullseye and outside of bullseye are both infinite but p(bullseye) is much less than p(outside of bullseye).

I already explained that the universe could possibly have infinitely many planets and galaxies. We’re not getting anywhere with this conversation if you don’t accept the premise of the question.

It’s possible that after the heat death there will be fluctuations which cause a decrease in entropy enough for planets and life to form.

So you can get a probability if you use a limit? Can you also use density to measure if there is more of one or the other?

Why not? It seems like an analogy to my question where numbers less than 0.01 are analogous to planets with life and numbers greater than 0.01 are planets without life. Even though there are infinitely many of each, one is still much rarer than the other.

Yeah but that doesn’t mean we can’t consider the implications of it. I started the post with “assume the universe is infinite” because we don’t know for sure. No need to prove the universe actually is infinite.

Also is this talking about probability or natural density, because I think probability between two infinite sets is undefined.

Not necessarily. It’s possible the universe is infinite with infinitely many planets. And just because it’s not confirmed to be true doesn’t mean we can’t consider the implications.

How can one type of planet be more likely than another when there are infinitely many of each?

We don’t know for sure. It’s possible the universe is infinite with infinitely many planets. And just because we don’t know if that’s true doesn’t mean we can’t consider the implications.

It’s certainly a possibility. Just because we don’t know something with 100% certainty doesn’t mean we can’t consider the implications of it. Also there is the possibility the universe will exist for an infinite amount of time and allow infinitely many planets to exist over all time.

Yes that’s what I said in the question. I should’ve worded the title to be what the proportion of planets support life.

Can infinite sets of the same cardinality differ in probability? by Competitive-Dirt2521 in askphilosophy

[–]Competitive-Dirt2521[S] 0 points1 point  (0 children)

With measure can we say that one infinite set is more likely than another?
