There are many possible solutions to the Fermi Paradox but a few have risen to particular prominence - including the "Grabby Aliens" hypothesis. Today, we'll explore what this solution proposes, what it assumes, and ultimately three reasons why I personally don't think it's right.
Written & presented by Prof. David Kipping. Edited by Jorge Casas. Special thanks to Robin Hanson for his discussions with me on this.
