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.”

An Evolution of Ancient Astronaut Theory's Proof and Proponents

Religion molds many people’s worldview and beliefs about our origin as a species. From a young age, and even as we grow older, we tend to hold on to aspects of those stories – many of which involve magic or divine phenomena. But as technology has progressed over those years, things that once seemed magical, now make perfect sense and fall within the widening realm of possibility. And as our modern worldview has become shaped by this techno-centric, materialist scope, the ancient astronaut theory has found an increasingly larger audience.

If you’re not familiar with Gaia’s content, maybe you’ve seen the program Ancient Aliens on History Channel, or possibly read Erich von Däniken’s classic book Chariots of the Gods? These series are founded on the ancient astronaut hypothesis; the assertion that if you reinterpret biblical accounts of supernatural gods with magic powers instead, as members of an advanced extraterrestrial race with advanced technology, their depictions make a lot more sense.

Arthur C. Clarke famously made this contention later when he said, “any sufficiently advanced technology is indistinguishable from magic.” And though it’s unclear whether Clarke ascribed to the belief, it’s likely he would have at least entertained it.
