Interesting.
It proposes the universe has properties allowing observers to exist, explaining why physical constants seem fine-tuned for life.
I don’t know if this true but it definitely could be as most civilizations are probably more advanced than the earth.
A survey of five million distant solar systems, aided by ‘neural network’ algorithms, has discovered 60 stars that appear to be surrounded by giant alien power plants.
Seven of the stars — so-called M-dwarf stars that range between 60 percent and 8 percent the size of our sun — were recorded giving off unexpectedly high infrared ‘heat signatures,’ according to the astronomers.

Today, you will discover the most advanced civilization in the universe, which terrifies scientists. Type 3 alien civilizations would wield more power than humans can imagine.

ABSTRACT. The search for extraterrestrial intelligence is currently being pursued using multiple techniques and in different wavelength bands. Dyson spheres, megastructures that could be constructed by advanced civilizations to harness the radiation energy of their host stars, represent a potential technosignature, that in principle may be hiding in public data already collected as part of large astronomical surveys. In this study, we present a comprehensive search for partial Dyson spheres by analysing optical and infrared observations from Gaia, 2MASS, and WISE. We develop a pipeline that employs multiple filters to identify potential candidates and reject interlopers in a sample of five million objects, which incorporates a convolutional neural network to help identify confusion in WISE data. Finally, the pipeline identifies seven candidates deserving of further analysis. All of these objects are M-dwarfs, for which astrophysical phenomena cannot easily account for the observed infrared excess emission.
There are three ways to look for evidence of alien technological civilizations. One is to look out for deliberate attempts by them to communicate their existence, for example, through radio broadcasts. Another is to look for evidence of them visiting the solar system. And a third option is to look for signs of large-scale engineering projects in space.
A team of astronomers have taken the third approach by searching through recent astronomical survey data to identify seven candidates for alien megastructures, known as Dyson spheres, “deserving of further analysis.”
This is a detailed study looking for “oddballs” among stars—objects that might be alien megastructures. However, the authors are careful not to make any overblown claims. The seven objects, all located within 1,000 light-years of Earth, are “M-dwarfs”—a class of stars that are smaller and less bright than the sun.
The search for life beyond Earth is really just getting started, but science has an encouraging early answer: there are plenty of planets in the galaxy, many with similarities to our own. But what we don’t know fills volumes. Observations from the ground and from space have confirmed thousands of planets beyond our solar system.
Astronomers have identified seven star systems in our galaxy that could potentially host a Dyson sphere — a hypothetical megastructure an alien civilization could build around a star or black hole to capture most of its power in the form of radiation.
The concept, first proposed by theoretical physicist Freeman Dyson in 1960, could take on a number of different shapes, from giant cage structures to ring shells to constellations of mirrors.
Of course, it’s an entirely theoretical idea. After all, we haven’t even discovered the existence of extraterrestrial life, let alone an intelligent alien civilization.
Although scanning this structure remotely could garner more technological advances I do think we need to consider safeguarding earth aswell.
Could unusual starlight patterns be the key to uncovering these mythical megastructures?
This is an issue that the character Ye Wenjie wrestles with in the first episode of Netflix’s 3 Body Problem. Working at a radio observatory, she does finally receive a message from a member of an alien civilization—telling her they are a pacifist and urging her not to respond to the message or Earth will be attacked.
The series will ultimately offer a detailed, elegant solution to the Fermi Paradox, but we will have to wait until the second season.
Or you can read the second book in Cixin Liu’s series, The Dark Forest. Without spoilers, the explanation set out in the books runs as follows: “The universe is a dark forest. Every civilization is an armed hunter stalking through the trees like a ghost, gently pushing aside branches that block the path and trying to tread without sound.”
