Dyson Spheres Key to Find Alien Civilizations Higher on Kardashev Scale
Searching for intelligent life in the universe? Then look for their energy source. An update on the hunt for Dyson Spheres.
In June of 1960, astrophysicist Freeman Dyson published his paper Search for Artificial Stellar Sources of Infrared Radiation in the journal Science. In it he argued a way to detect intelligent life in the universe by finding their energy signature that would be created by, he presumed a highly advanced technology.
He wrote, “If extraterrestrial intelligent beings exist and have reached a high level of technical development, one byproduct of their energy metabolism is likely to be the large-scale conversion of starlight into far-infrared radiation.”
Dyson, who died one year ago this month at age 96, believed that an advanced technology would harness solar power from a star with an array of solar panels. He explained in a 2003 interview that he once described it as a biosphere, but since then this theory has been known as a Dyson Sphere.
Dr. Seth Shostak Sr. Astronomer at the SETI Institute explains, “If you’re looking for E.T., if you’re looking for intelligence elsewhere in the universe, you’ve got to figure there are societies out there that are way more advanced than we are, you know the universe has been around for a long time. And they may have constructed something like a Dyson Sphere, or more accurately a Dyson Swarm, or something we can see. And there have actually been searches for alien Dyson Spheres.”
Were Recent Radio Signals From Proxima Centauri Evidence of Alien Life?
The mystery signal from space… what was actually broadcast from Proxima Centauri?
In December 2020, news broke of a mysterious signal coming from the area of Proxima Centauri. Ufologists and astronomers were excited by the news as the planet Proxima B may be able to host life. The signal was originally detected in the spring of 2019 by the Breakthrough Listen Project using the Parkes Telescope in Australia. But the significance of what they found was only recently made public.
But what was so intriguing about this transmission?
