🔭 KI-Forschung hat die Art und Weise revolutioniert, wie wir das Universum betrachten.

Durch fortschrittliche Algorithmen können wir jetzt riesige Datenmengen analysieren und komplexe Muster erkennen, die uns bisher verborgen waren. #KI #Astrophysik
💫 Eines der bekanntesten Beispiele für den Einfluss von KI auf die Astrophysik ist die Entdeckung von Exoplaneten.

AI-gestützte Analysemethoden haben es ermöglicht, Tausende von potenziell bewohnbaren Planeten in unserer Galaxie zu identifizieren. #Exoplaneten #KI

Today in UFO History - Sagan Speech
November 15, 1962 - Am. Rocket Society Conference

2/distribution of technical civilizations in the galaxy. Using Frank D. Drake’s equation to suggest that 0.001% of stars in the sky have a planet on them on which an advanced civilization resides, Sagan suggests the nearest such advanced civilization is several hundred light Image

Today In UFO/ET Histoy - Space Signals?

2/the alleged extraterrestrial signals detected by Nikola Tesla, Guglielmo Marconi, and David Todd between 1899 and 1924. They speculate that the signal source was 11 light years away, perhaps the Epsilon Eridani system. [Eberhart] ImageImageImageImage
"Rocket Society Report on Space Signals", NICAP U.F.O. Investigator Jan./Feb. 1963 Vol.II, No.7, pg.4;

The actual paper was very difficult to find, it seems to have been wiped from most places on the internet. But I have provided it here. ImageImageImageImage

Let's talk a bit about the pessimistic "Dark Forest" hypothesis. Because it's entirely logical but nevertheless not a credible explanation for the Fermi Paradox, i.e., that we haven't seen alien civilizations. 1/
The "Dark Forest" is one of the potential answers to the famous Fermi Paradox listed by David Brin in 1983, and more recently the name of a book by Chinese sci-fi author Liu Cixin.

In short: space-faring civilization would see other intelligent life as an inevitable threat. 2/
Therefore, goes the hypothesis, any nascent life should be destroyed before it actually becomes a threat.

To a lot of people, this makes total sense. Life seems so brutish and violent. Perhaps alien civilizations wipe out everyone they detect.

But actually it doesn't. 3/

Today in ET Life History - The Drake Equestion
November 1, 1961 - The Order of the Dolphin

2/Frank Drake writes this equation on a chalkboard: N = R fp ne fl fi fc L. The equation, the Green Bank Formula, summarizes the main concepts that scientists must contemplate when considering the question of extraterrestrial life capable of communicating by radio across space.
3/ It is more properly thought of as an approximation rather than as a serious attempt to determine a precise number. Allen Ginsberg, Timothy Leary, and John C. Lilly in 1991.

Here's an interesting paper that tries to answer the Fermi Paradox: why haven't we seen aliens yet?

I have my own answer, though.

I don't believe species capable of crossing interstellar distances COULD be very expansionist. #SETI
A strongly expansionist civilization - one that basically takes over every possible nook and cranny in the parts of the universe it can reach - implies a civilization that hasn't solved the problem of limiting its powers. It doesn't live within its means.
But technologies that are needed for interstellar travel are extremely powerful.

A civilization that develops such technologies before learning to limit its powers is one civil war or industrial accident away from an existential catastrophe.

Seguimos la quincena temática sobre el #ArteAntiguoEgipto para el #TwitterCultural.

¿Conocéis los Guerreros de terracota enterrados cerca del autoproclamado primer emperador de China de la Dinastía Qin, Qin Shi Huang? Pues en Egipto tenemos algo parecido: los #ushebtis.

Sigue👇🏽 Image
Los #Shabtis, #Shauabtis o #Ushebtis (el nombre cambia según la época pero su significado se mantiene: los que responden) son estatuillas funerarias, de aspecto momiforme, originadas en la segunda mitad del Reino Medio, en la Dinastía XII, entre el 1962 y el 1787 a.C.

Sigue👇🏽 Image
En la primera dinastía a los faraones del antiguo Egipto los enterraban junto a s esposa y sus sirvientes, es decir: sacrificaban sus vidas para acompañar al faraón en "la otra vida".
Esto evolucionó a elementos simbólicos y mágicos (pinturas, relieves...) y estatuillas.

I had questions about the plausibility of what I saw. Many others did as well…
Regardless, I think it captured a big limitation on human colonization of the solar system and beyond: our psyches. I get moderately depressed with lack of sunlight in winter. What would happen to me traveling 9 months in the total black of space? Add in the solitude, the

CONGRESIONAL UPDATE: Contrary to earlier pessimistic assessments, it now appears that the long-stalled Intelligence Authorization Act (IAA), with its UAP-related cargo, will be enacted after all.
This is the bill to which the Senate Select Committee on Intelligence (SSCI) last June linked a call for an unclassified UAP report in 6 months. The IAA now has been incorporated into a massive end-of-session bill, containing coronavirus-relief provisions, funding for
federal agencies through Sept 2021, etc. This 5,593-page package is referred to as "the omni." Unless something goes badly awry, it should be signed into law within days.
