The Kardashev Scale & Dyson Spheres

An exploration of the Kardashev scale and Dyson spheres. It’s possible that in a few centuries Humans may be able to capture all the energy on Earth, in a few thousand years we might be able to capture all the energy from the Sun, and we might be able to harvest all the energy from every star in our galaxy in 100,000 to one million years. In this video, we discuss the Kardashev scale and look in detail on each civilization type, as well as discussing Dyson spheres.

In this episode, we will be looking at von Neumann probes, discussing many reasons why you’d use them, tied in with the Fermi paradox.
