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.”
Harvard Professor Starts Independent Investigation to Find Aliens
The search for signs of extraterrestrial life is getting a boost from scientists. Could this grassroots transparent effort answer the biggest question in the universe: are we alone?
The quest to find evidence of higher lifeforms is getting a boost from higher education. Harvard Professor of Science Avi Loeb, has just launched the Galileo Project, the goal of which is to bring the search for “Extraterrestrial Technological Civilizations (ETCs) from accidental or anecdotal observations and legends to the mainstream of transparent, validated, and systematic scientific research.”
Professor Loeb, who published his book “extraterrestrial: The First Sign of Intelligent Life Beyond Earth,” which claims Oumuamua, the first known interstellar object to pass through our solar system, could be an extraterrestrial artifact.
His research, coupled with the US government’s recent report on unidentified aerial phenomena, spurred him to action.
