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 ...

Researchers explore Dyson spheres around red dwarf stars, detailing infrared signatures, equilibrium temperatures, and potential candidates for observation using modern telescopes.

Heh, yeah, no kidding. I mean you've already _got_ construction bots to start with! I'm sure the blue prints will be sooner rather than later. It'd be also nice to have the logistics towers be able to ...

Assuming intelligent aliens know how to harvest energy from stars, would humanity be able to spot these high-level structures?

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 ...

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 ...

The Dyson Sphere concept is a staple of science fiction, from Star Trek to the novels of Larry Niven, and it sounds like a dream come true: a way to harvest almost all of the immense energy output of ...

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 ...
