Fermi paradox:

There's a story about Enrico Fermi chatting with Edward Teller, Herbert York, and Emil Konopinski, whilst walking for lunch. They discussed UFO reports, when suddenly Enrico Fermi, out of the blue, said "but where is everyone?"

The Fermi paradox goes something like this: Humans are sending out all sorts of signals into space, which can be picked up by far-away star systems. Thus, if there are aliens with highly advanced technology, they should be able to see that we're here on Earth. Vice versa, if alien civilizations, like us, are sending out radio signals into space, then we should be seeing them. So why haven't we found any aliens?

There are between 100 and 400 billion stars in the Milky Way, each with anywhere between 1-20 planets. A huge number of those planets contain water and are at a hospitable distance away from the star, just like us. So the Milky Way should be teeming with life. Even more puzzling is that some of those alien communities should be much more advanced than us and could've started populating the Milky Way. But if so, why does everything look dead?

It's bewildering.

Give context, don't be lazy.

Yes, drake equation is a very interesting way to quantify the probability of life existing near us and gives some insight as to what the possible explanations are.

The greatest limitation we have right now is that we have a sample size of 1 when it comes to known life in the cosmos.

L = the length of time for which such civilizations release detectable signals into space

 Maybe the communicable civilizations learned, before we developed the tech, that they should not be sending alarms out into the ethos to notify of their location. War, colonization, and disease could be the consequences of transgalactic contact.

Maybe we are the buffoons stills calling out for the bringers of our conquer.

 

 

 

Also too lazy to find the links now, but random radio signals have been picked up from deep space a bunch of times actually. Signals not created by humans.

But that would mean we're headed for an imminent disaster.

Really? I'd be very interested.

Aren't those radio signals pulsars or other star-related phenomena?  Even those that seem eerily regular?

Which do you think will happen first: discover extraterrestrial alien life or develop sentient AI?  Perhaps life on this planet is extraterrestrial in origin, or its development has been.  The whole biological program was in order to get that AI online.
