This is true for all values. Just because the sample size is low doesn't mean we cannot assign values. The chance of life arising on an arbitrary planet is .091 if you count Pluto as a planet and .10 if you do not, by Laplace's Law of Succession.

There could be creatures as intelligent as dolphins or elephants on other worlds, and we'd never know it. Smart as they are, they don't make signals we can listen to across lightyears.

We've only been making that kind of noise for a century or so, and if there were another human like technology nearby, it would have to be within about twenty light years for us to hear it.

TL;DR: we haven't been looking long enough or hard enough to make any reasonable assumptions

Maybe when we turn on the JWT we'll start seeing all kinds of hallmarks of biology on exoplanets.

Well, think about it. How would we find life?

We can't look for signs of biological life elsewhere in the universe - telescopes powerful enough to look at exoplanets have only existed for the last decade or so, and they're still struggling to learn anything about the actual conditions on those planets.

And signs of intelligent life? Our current searches could only find very large megaprojects that would substantially change the appearance of a star, or extremely powerful radio messages either specifically directed at us or beamed at all directions into the void - neither of which is it certain that an alien civilization would do, or even want to.

I don't think it's mind-boggling. I think we're mind-bogglingly small in an isolated and remote corner of an insignificant part of a minor galaxy.


I want to make some analogy about islands, like we're some primitive little tribe on an island in the middle of a vast empty sea with MILLIONS of insignificant islands, but even that doesn't do the scale justice.

There's like, the busy parts of the universe, say the Virgo Supercluster. That's a dense network of disparate galactic metropolii. Then there's the distant rural backwaters that the aliens rarely visit and don't usually think about.

Then there's the vast empty void, then there's a small and inconsequential little cluster with a handful of typical galaxies, it's like the most forgotten backwoods area that's so far out in the empty wilderness that no one even knows it's there.

We're in the most empty and unremarkable corner of THAT.

It's ridiculous how small and irrelevant we are.

There are probably intergalactic wars taking place right at this very moment on scales we can't even imagine, of import that we'll never comprehend.

Maybe someday we'll be a footnote in some pan-galactic biological index or anthropological survey. I hope so.

>> No.6992215

Because our furthest radio waves are only about 76 lightyears away, and because of the inverse square law they dissipate into nearly nothing before we've ever even had a hope to contact aliens, we'd need a high gain antenna, but for that to be any use, we'd already need to know where aliens are.

I'm not even the guy that you are replying to, but he didn't made the analogy with "life" in mind, he said whales. It is the most common analogy ever.

If i'm looking for whales in the oceans and i only go through a droplet of it, ofc i won't find whales.

The only thing that is unlikely is life not being "common" in the universe, it is just chemistry that needs the right conditions, and probabilities are that there are thousands of planets that have life of some sort across the observable universe.

Just because these planets exist it doesn't make us obligated to find them, as much as we know there could be thousands of planets that used to have life that already perished and we don't really care for them.
