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 ...

Dyson spheres and rings could exist in the universe, if we’re dealing with a certain type of star system. One physicist tapped into centuries of research on the three body problem of celestial ...

The search for alien life takes many forms, from identifying Earth-like planets to scanning for extraterrestrial signals.

A cosmologist suggests we should look for exploration, along with energy signatures, to try and find aliens. Dyson spheres of some kind may be built to harvest energy from dark matter in black holes.

There’s a new wrinkle in the connection between the artificial intelligence race, and the drive to explore deep space. It’s getting a shot in the arm today with a headline from The Information that ...

Dyson calculated that a shell made from a planet with the mass of Jupiter could completely enclose the sun at roughly the orbit of Earth. But the gravity inside a hollow shell cancels out, which means ...
