Kinda ironic handing a 'Lifetime Achievement' award to someone when he calculates that the collective 'lifetime' of our species is nearly up. 😉

Two things I've always thought about the Fermi Paradox
1) We don't know what technology They use, so it's just guesswork as to what we're looking for. A bit presumptuous to write off the whole Universe as empty.
2) The Universe is BIG and we're barely explored it yet, we've only been listening for radio for about a 100 Earth years, that's nothing in this big old universe. And who wants to communicate at the Speed of Light?

It’s about part of the #Fermi_Paradox #FermiParadox

“Great Silence” in narrowband radio technosignature searches over the past several decades may be caused by spectral broadening in interplanetary medium.

Turbulent plasma near distant stars could blur ultra-narrow signals before they leave their home star systems, making them difficult to detect.

Exo–IPM Scattering as a Hidden Gatekeeper of Narrowband Technosignatures https://iopscience.iop.org/article/10.3847/1538-4357/ae3d33

"Narrowband radio technosignatures can be significantly modulated by the host star’s exoplanetary interplanetary medium (Exo-IPM), where turbulence in stellar winds and coronal mass ejections (CMEs) imprint spectral broadening. ..

🌌 The Fermi paradox begins with a simple question: a universe rich with stars and worlds, and a sky that still feels quiet. How do we separate a true signal from our own interference, and what might silence be telling us?

Das #FermiParadox war für mich nie schlüssig. Bei den Distanzen müssten die Aliens entweder soviel länger leben als wir, dass ein Kontakt eh nicht sinnvoll wäre, oder die Relativitätstheorie ist so falsch wie es kein Physiker annimmt.

Aliens, die Kontakt mit uns aufnehmen können, müssten uns heute immer noch wie Götter vorkommen. Und Däniken hatte trotzdem nicht recht.

maybe we haven't been visited by aliens because they look at our rating and go "just One star? eww I'll pass"

Unintentional "leaked signals" are millions-fold weaker than intentional #METI signals 📶. Given the number of messages already sent to target stars https://en.wikipedia.org/wiki/Active_SETI#Transmissions, do you expect a reply

"Of course it remains possible that #alien 👽 mindsets differ substantially from our own. Perhaps no other race is so cynical about the intentions of others, or wedded to game theory analysis of the potential threat. Perhaps no other species is quite so #aggressive as we imagine" 🤔 https://warwick.ac.uk/fac/sci/physics/research/astro/people/stanway/sciencefiction/cosmicstories/the_dark_forest

@tatzelbrumm @larsweisbrod @yodathan Apropos #FermiParadox Das Ende von Allem ist noch nicht das Ende der Menschheit. Irgendwann nach dem Auftreten des Kessler-Syndroms wird Raumfahrt wieder möglich sein. Wir werden nur nicht dabei sein.

I am increasingly feeling like the Great Filter is Politics. #FermiParadox

Are you alone is (usually) a relatively easy question to answer...

But are WE (e.g., life on Earth) alone (in the Universe) is a bit more complex...

Enter the Drake Equation for some of your important are we alone pondering...

Mein Lieblingsfilm zum #Fermiparadox ist nach wie vor "Men in Black", aber auf den Spielberg-Film bin ich auch gespannt!

Wieder hat Steven #Spielberg die Ankündigung eines Alien - #Apokalypse - Thrillers gekonnt in der #Vorweihnachtszeit platziert.

Schon der Trailer von "Disclosure Day" - deutsch: Enthüllungstag, also Tag der Enthüllung - zeigt eine christliche #Ordensschwester , die das #Fermiparadox religiös zitiert: Warum sollte #Gott ein so großes #Universum nur für uns erschaffen haben?

Danke, dass muss auch der @silberspur zum #FermiParadox sehen! 👆 Er hat dazu & zum #Fossilismus just heute Morgen hier auf dem #Blog klug kommentiert.

Ha ha I have been thinking this about the #fermiParadox most of this year.

Whichever way you cut the logic.

We can either have dumb #AI
or Smart, motivated AI that sooner or later will compete with biologicals.

The #FermiParadox is the biologicals giving birth to #AGI and #ASI then being discarded, like the shell of an egg...

A visitor from another star system, 3I/ATLAS, is currently journeying through our celestial neighborhood.

My latest article explores this fascinating thought experiment: What if we detected a signal from 3I/ATLAS, encoded in the Fibonacci sequence—the mathematical blueprint of life itself?
