If there are alien civilizations in the Universe, some of them could be super advanced. So advanced that they can rip apart planets and create vast shells surrounding a star to capture all its energy.

Dyson spheres, theoretical megastructures proposed by physicist Freeman Dyson in 1960, were hypothesised to be constructed by advanced civilisations to harvest the energy of host stars. It’s thought ...

The bold question-askers at What If explore what building a Dyson Sphere around the sun could achieve.

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 ...
