The Dyson Sphere: How to Build a Star Cage

from Window to the Future · host Thomas Rackers

In our special 30th episode, we go beyond the limits of Earth. We explore the Dyson Sphere—a theoretical megastructure designed to capture the total energy output of a star. How would we build it? Why would we need to "eat" a planet to make it happen? And could we find alien civilizations by looking for these giant structures in deep space?
