Imagine flying through the galaxy, minding your own business and suddenly you see a structure that is very large. It's so big, in fact, that it surrounds a star! It's a Dyson Sphere!

This week we explore the concept of a Dyson Sphere, first seen in the Star Trek universe in the Season 6 episode "Relics" from The Next Generation.

First proposed in 1937, the concept was first scientifically theorized by futurists Freeman Dyson in 1960. This week hosts Kelly Casto and Bob Turner talk about this concept and what it might actually look like, scientifically speaking.
