Dyson's PencilVac is so thin and light it feels more like a broom than a cordless vacuum. Here's how using it went.

Here’s how it works. Dyson spheres are hypothetical artificial megastructures built around a star to collect all of its radiant energy. In theory, detecting a Dyson sphere could be a way to find ...

“As a young scientist, Dyson showed that three competing quantum theories were actually the same theory — he summarily ended ...

The theory that has got the most traction is that the dips are caused by an alien megastructure, similar to the Dyson sphere first proposed by theoretical physicist Freeman Dyson in 1960.

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 ...

When people hear “Dyson sphere,” their first thought is ... But that’s exactly what it is, at least in theory. Now, some scientists believe they might have found not one, but seven in ...

The theory of quantum electrodynamics that he helped establish is the prototype that was eventually elaborated into the Standard Model of particle physics. In the 1950s, Dyson made multiple ...
