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, 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 ...

Dyson spheres, theoretical megastructures proposed by physicist Freeman Dyson in 1960, were hypothesised to be constructed by advanced civilisations to harvest the energy of host stars. It’s thought ...

Imagine you are an astronomer looking deep into space in search of extraterrestrial life. You spot a star that is emitting infrared radiation in anomalous fashion. You zoom in and see a swarm of solar ...

The search for extraterrestrial intelligence (SETI) has been conducted for nearly 60 years. A Dyson Sphere, a spherical structure that surrounds a star and transports its radiative energy outward as ...

There are two problems with arguments in favour of Dyson spheres, massive structures that advanced alien species might build to capture all of a star’s energy. First, long before a civilisation could ...
