Exactly why there are no life bearing planets except earth.
It’s not just that they should be there.
They should have reached out and found us a thousand times over.
They are not there.
If they found us, would they be stupid enough to:
—Give away their location
—Let us know they found us
One definition of intelligence is the understanding of the necessity to hide your intelligence from potentially hostile “others”.
By that definition, btw, humans are stunningly stupid.
Our solar system has 3 rocky planets in the Goldilocks zone but only 1 in habitable.
I can recommend the book “Rare Earth” for a full explanation.
We’re literally 1 in a million or billion or more.
Disagree. If say a species was significantly advanced that they were ahead of us technologically then they likely don’t use anything like am/fm or any radio bands but something digital and perhaps laser. It could be simply that their oldschool communications and media has already passed us by. Their is also the chance that it simply hasn’t been enough time to reach us or they haven’t reached the level necessary to broadcast information. There are a million reasons why we haven’t heard from any of them. After all our first broadcasts are just 110 light years away.
It depends where in ‘time’ we are. We could be the first to reach this level of sentience in which case we’re basically alone at this level... or we’re the latecomers and all the other sentients at this level have ascended, evolved beyond our understanding, or simply died out.
The other thing is that the speed of light, as we understand physics right now, is the uppermost speedlimit. That makes going places a bit difficult as well as making communication a problem. We still can’t talk much beyond Alpha Centauri with our radio technology, and that’s with *years* of lightspeed lag on the roundtrip if we were to build such a setup.
I disagree -- there are many possibilities. Just a few:
Faster than light travel is not possible, or is so expensive that it is not worth coming to this backwater planet.
They came 10,000 years ago and left -- Oog the caveman did not seem like a good trading partner.
Panspermia seeded the earth long, long ago and we are somewhat like them.
Intelligent life seeded the earth long, long ago will someday come back to round up their cattle.
They have been here and they are us.
Unless a universal law of biology says all advanced civilizationS destroy themselves before they develop interstellar communications or travel.
Jeez.
The Universe appears to be infinite. Unless you’ve found some ‘wall’ that we run up against, how in the world can you think that they all should have reached out and ‘found’ us? Many could be at the same level of tech that we are now. Others could be hundreds of years behind us.
And others could be so far ahead of us, that they are attempting to communicate in ways we can’t even recognize - or don’t try because they just Don’t Care!
If they are technologically behind us, they are incapable of it. If they are even four thousand years more advanced, we have nothing to offer them. Would we spend billions of dollars, maybe trillions, to go have a big pow-wow with cavemen halfway across the galaxy?
Just because we can’t detect any doesn’t mean nobody is out there. There’s a hundred billion stars in this galaxy on the low end. An earth-like planet bearing life would be... difficult to find.
please read this sentence:
“[Truly Earthlike planets] are not hiding per se, it’s just that the sensitivity of our telescopes is simply not good enough yet [to find them],”

I recently read the book “Three Body Problem” and it deals with just these kinds of issues. It’s science fiction, but it’s also a thought experiment about what “first contact” would be like — and they are not friendly. The author is a Chinese physicist, but his English translator must have been a genius because it’s a good read!
