SETI (Search For Extraterrestrial Intelligence): Compendium / Miscellaneous

"In our solar system's proverbial "no man's land," a deep space realm beyond the planets, scientists detected unexpected activity.

This remote area, inhabited by ice-clad worlds like Pluto (a dwarf planet), is called the Kuiper Belt, a donut-shaped region surrounding much of our solar system. It's a relatively little known place, but millions of frozen, "dead" objects are thought to orbit there. Now, astronomers pointed the powerful James Webb Space Telescope at some of these icy objects, and found evidence that they're not so dead after all.

"We see some interesting signs of hot times in cool places," Christopher Glein, a scientist at the Southwest Research Institute who researches icy worlds, said in a statement."

Oh no! Kuiper Belt warming. :omg:
 
This warming effect is presumably caused by tidal interactions. Although the Kuiper Belt Objects (KBOs) are all very far apart, about 11% of them have satellites, including Eris, Pluto, Gonggong, Makemake, Haumea and Quaoar, and several (like Pluto) have more than one. Tidal interactions between these multiple satellites can cause heating, which is why Pluto and Charon have got such interesting surfaces.

Additionally these objects may occasionally collide, causing energetic events that release volatiles and solid debris; eventually much of this ejecta will fall back onto the object, or form a new moon.
 
Just leave this here:

"According to the (ret) head of a pan European radio telescope project, an extraterrestrial signal was detected 11 light years away in 2019. He told me, we are in regular contact with the aliens. Is this true? How would we speak in real time to an ET, 11 light yers away? maybe with Quantum Tunneling Communication. Some of this story makes sense, other bits are pure science fiction. Is this the BIG reveal we have all bee waiting for, or is it just bollocks?"


First came across this chap when he got involved in the Calvine UFO photo debate, not sure what to make of this...?

He has the classic nutty professor look.
 
Paul_Exeter said:
Yeah, he clearly plays on that, too. His Calvine stuff was interesting but also essentially speculation on the findings of David Clarke. His stuff is interesting but not necessarily factual

I always take his videos with a pinch of salt. He's not actually a professor of anything, he just has the 'mad scientist' look.

"Why extra-terrestrial life might not seem so 'alien' after all​

Could we ever conceive of what an alien species might be like? It may not be so hard, since there are universal laws that constrain evolution."

That article falls over very early on:
First among these ‘universal laws of biology’ is that all life in the Universe must have evolved through natural selection.

Um, no. Some of it might be bio-engineered by a pre-existing technological civilisation that did arise through natural selection, or there may be several periods of bio-engineering interspersed with periods of natural selection. Who knows?
 

A Study Suggests We Found Potential Evidence of Dyson Spheres—and Alien Civilizations​


  • For more than half a century, scientists have wondered if searching for technosignatures like Dyson Spheres from super-advanced civilizations could help us discover intelligent life elsewhere in the universe.
  • Two new studies analyze data from star-gazing satellites to develop a framework for eliminating false positives or potential natural explanations in that search.
  • Each study found evidence that a handful of stars among the millions observed contain excess radiation that’s consistent with potential Dyson spheres and can’t be immediately explained away as a natural phenomenon.

I expect another paper will seen emerge to refute this but it is tantalising all the same

Another take on this story here:

Alien 'Dyson sphere' megastructures could surround at least 7 stars in our galaxy, new studies suggest​

Researchers have identified at least seven stars in our galaxy that may be surrounded by super-advanced alien megastructures, known as Dyson spheres. However, this is not the only explanation for these stars.

Then there is AI to worry about:

This Wild, Believable Theory Suggest AI Is Blocking Us From Alien Contact​

What if AI represents a formidable bottleneck in the development of all civilizations, one so challenging that it thwarts their long-term survival?

But what if this [AI] milestone isn’t just a remarkable achievement? What if it also represents a formidable bottleneck in the development of all civilizations, one so challenging that it thwarts their long-term survival?

he great filter hypothesis is ultimately a proposed solution to the Fermi Paradox. This questions why, in a universe vast and ancient enough to host billions of potentially habitable planets, we have not detected any signs of alien civilizations. The hypothesis suggests there are insurmountable hurdles in the evolutionary timeline of civilizations that prevent them from developing into space-faring entities.
