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 ...

In 1960, British theoretical physicist Freeman Dyson published a one-page paper in the journal Science that offered perhaps the most hopeful vision ever conceived of humanity’s technological future.

The gargantuan artificial construct enveloping your local star is going to be rather difficult to miss, even from a few light years away. And given the literally astronomical costs of resources needed ...

Simon Goodwin does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond ...

The Sphere would not gravitationally bind to its star in a stable fashion. This is perhaps counterintuitive; you might think that a perfect sphere around a star would be stable. But if any part of the ...

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 ...

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 ...

Dyson spheres and rings have always held a special fascination for me. The concept is simple: build a great big structure either as a sphere or ring to harness the energy from a star. Dyson rings are ...

Side note: if we can build a structure around the sun, we won’t need local energy storage for said structure. Also, I’m with others in thinking a swarm is the way to go. Though I don’t think that ...
