We’d need an astronomical amount of resources to construct a Dyson sphere, a giant theoretical shell that would harvest all of a given star’s energy, around the Sun. In fact, as science journalist ...

Seven different stars in our galaxy may show signs of being contained within Dyson spheres, megastructures that could be constructed by advanced civilizations to harness radiation energy from stars, ...

In 1960, visionary physicist Freeman Dyson proposed that an advanced alien civilization would someday quit fooling around with kindergarten-level stuff like wind turbines and nuclear reactors and ...

In 1960, legendary physicist Freeman Dyson published his seminal paper "Search for Artificial Stellar Sources of Infrared Radiation," wherein he proposed that there could be extraterrestrial ...

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 ...

Recently, according to Live Science, the results of two scientific studies have been released that could, if verified, prove the existence of advanced alien civilizations elsewhere in the universe ...

Dyson spheres, the hypothetical mega-structures that advanced alien civilizations might use to enclose a star and harness its energy, suffer from a fatal flaw: They are catastrophically unstable. But ...

If extraterrestrial intelligent life is out there —- and everybody and their brother now seems to think so —- it could hypothetically be as much as a few billion years ahead of us. In the ongoing hunt ...
