Unusual light fluctuations from Tabby’s Star may indicate a mega-structure built by an advanced civilization, resembling a possible Dyson Sphere harvesting a star’s energy. Trump reveals congressman’s ...

In the 1960s, physicist Freeman Dyson proposed that advanced alien civilizations could be building enormous megastructures around a star to harness its energy. Such a move would allow a civilization ...

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 ...

A researcher from German research institute Forschungszentrum Jülich has investigated for the first time the possibility of designing a Dyson sphere utilizing photovoltaic modules. A Dyson sphere is a ...

In the realm of science fiction, Dyson spheres and ringworlds have been staples for decades. But it is well known that the simplest designs are unstable against gravitational forces and would thus be ...

They used high-resolution e-MERLIN and EVN (e-VLBI) observations of a radio source associated with Dyson Sphere candidate G, identified as part of Project Hephaistos. The radio source, VLASS ...

In the more than 60 years in which scientists have engaged in the Search for Extraterrestrial Intelligence (SETI), several potential examples of technological activity ("technosignatures") have been ...

Alfredo has a PhD in Astrophysics and a Master's in Quantum Fields and Fundamental Forces from Imperial College London. Alfredo has a PhD in Astrophysics and a Master's in Quantum Fields and ...

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 ...

When people hear “Dyson sphere,” their first thought is probably a heavy-duty vacuum. They certainly don’t think of a megastructure surrounding and harnessing a star’s energy with the purpose of ...
