Dyson estimated that such a construction would be visible through its infrared emission, as the sphere would heat up while absorbing stellar light. However, a solid sphere around a single star is ...

Is it possible to build a Dyson sphere that isn't catastrophically unstable? New research says yes, but only in one type of ...

But McInnes did find one stable — and useful — configuration. This only happens in binary systems in which one star is much smaller than the other. In that specific case, the Dyson sphere can ...

Dyson calculated that a shell made from a planet with the mass of Jupiter could completely enclose the sun at roughly the orbit of Earth. But the gravity inside a hollow shell cancels out, which ...
