Can it ever be solved ?

What's the question?


By Francois Lacombe (Franc0is) on Thursday, November 16, 2023 - 5:04 am:

The Fermi Paradox is the notion that the universe is very old and very big, and it should have produced advanced civilizations well before Earth even formed, and these civilizations would have had time to colonized every star system by now, including our own. Aliens should be everywhere, and their presence be obvious even with casual observations, but we see nothing, even with our best instruments, we appear to be the only ones around. Why is that, where is everybody? That's the paradox. It is named after Enrico Fermi, who asked that very question during a conversation with fellow physicists in the 1950's.

Got your answer, Winters.

Satisfied?


By Francois Lacombe (Franc0is) on Thursday, November 16, 2023 - 6:31 am:

Actually, I answered Smartalec's question, Jeff's question is still unanswered.


By Smart Alec (Smartalec) on Thursday, November 16, 2023 - 2:07 pm:

Thanks. Most people who use the phrase "Fermi Paradox" either assume that everyone is familiar with the actual hypothesis and don't explain anything, or they are just using the phrase to 'sound smart'.


By Tim McCree (Tim_m) on Friday, November 17, 2023 - 5:08 am:

I suspect that, in the case of Winters, it's to "sound smart."

Additionally Fermi came up with this idea before we knew just how dangerous and endemic to life the universe can be.

We just assumed life was common because it was everywhere around us (on Earth) and we assumed this would be true out there as well. Which is kind of like assuming it must be warm at the poles because you grew up on the equator. ;-) Assuming favorable local conditions everywhere is just a bit naive.

Interesting article I found
Related to the Fermi Paradox, I learned new things from it

Is it just me or is there a certain... 'desperation' amongst people trying to find aliens that may not exist?

It sometimes feels like a religion to some people.

If you think about it, there was really only a 100 year window where Earth would have been easily detectible by any extraterrestrial civilizations.

We've move a lot of our comms infrastructure to either lower powered radio, or to cable/fiber.

Assuming that there are some other civilizations out there, I'm wondering if we're running up against that, or possibly up against some advanced form of communications. Imagine, for example, our technology trying to detect a hypothetical subspace (ala Trek) network. We wouldn't even know it was there.


By Tim McCree (Tim_m) on Saturday, December 02, 2023 - 5:17 am:

Maybe Mr. Lovecraft was right.

Any aliens out there are so different from us that we have no chance of understanding, or communicating, with them.
