A scientific study published by researchers from the Swedish University of Uppsala and the University of Heidelberg, in Germany, suggests that there are more than 8,000 extraterrestrial megastructures in deep space, surrounding stars.
By building megastructures known as Dyson spheres, advanced civilizations could harness some of their star\’s energy. In this way, they would rise on the Kardashev scale towards type II.
Therefore, experts believe that there are at least 8,000 megastructures in the Universe, absorbing the power of the stars.
8,000 megastructures in the universe
The study called “SETI With Gaia: The Observational Signatures of Nearly Complete Dyson Spheres” proposes that the Universe is full of extraterrestrial civilizations that have the means and technology to create supermassive megastructures.
The team may have found “signs” that would suggest they were built many suns away. The study suggests that there are signs of up to 8,000 of these extraterrestrial megastructures.
“We found that a small fraction of stars show distance discrepancies of the type expected for near-complete Dyson spheres.
We found that 8,000 stars have sufficient data quality to allow potential Dyson Sphere candidates to be identified efficiently.”
One of the new study\’s leading candidates is a star called TYC 6111-1162-1. Experts call her the “most interesting individual candidate for further investigation.”
This means that it is the most likely star to have a Dyson sphere surrounding it. This conclusion came after analyzing the data obtained by the Gaia spacecraft of the European Space Agency.
“The Gaia mission in the coming years will enable searches for Dyson spheres, which are complementary to searches based on residual heat signatures at infrared wavelengths. Such a limited search is also possible at the present time, by combining Gaia\’s parallax distances with spectrophotometric distances from ground-based surveys.”
A map of Dyson spheres
Experts claim that, within this massive map that Gaia assembled, they found evidence of possible signs of megastructures.
As the study noted, several searches were made for possible Dyson spheres in the distant past. Unfortunately, none of them had positive results. Experts point out that building these massive structures in space is not easy. In addition, if it requires enormous amounts of material, its construction time would be extremely long.
So, in a new way of looking for the Dyson spheres, they hypothesize that instead of being a huge, solid structure, these spheres are also a group of smaller power plants that would be strategically placed around an alien star.
“The Dyson sphere is not usually thought of as a solid shell. But more like a dense, spherical swarm. Or an envelope of absorbing satellites, with each satellite absorbing a small fraction of the stellar radiation.”
Humanity is already preparing a plan that could lead us to create our first megastructure in about 5 years. By wrapping the Sun in an array of solar panels, the human race would become a Kardashev Type II civilization, capable of using some of the sun\’s energy output to meet its energy needs.
