Black holes are more than just massive objects that swallow everything around them—they're also one of the universe's biggest and most stable energy sources.

That would make them invaluable to the type of civilization that needs huge amounts of power, such as a Type II Kardashev civilization.

But to harness all of that power, the civilization would have to encircle the entire black hole with something that could capture the power it is emitting.

Even a single sphere around a single stellar-mass black hole would be enough to push any civilization that created it into Type II territory, giving it a level of power output unimaginable with current technology.

What Is A Dyson Sphere?

A Dyson Sphere is a megastructure that could be built around a star to harness all the solar energy it gives off.

In this video we talk about the different kinds of Dyson Spheres, Dyson Clouds and other megastructures that could be built - and how we might even detect them from Earth.

Could We Detect Dyson Swarms?

Dyson Spheres (and Swarms) should actually be pretty easy to detect across the Universe.
