Dead Planets Society: #11 Cube Earth Part Two

22 November 2023

About this episode

Turning the Earth into a cube, the gift that just keeps giving. Last episode we had fish bowl spaceships, this time we have sea monsters!

If you thought cubifying the Earth couldn’t get more wacky, you’re in for a treat. In the Dead Planets Society season finale, Leah Crane and Chelsea Whyte are once again joined by geophysicist Mika McKinnon. This time she explains what time would be like on a 6-faced planet, how you’d be able to experience all four seasons in a single day on Cube Earth and why this re-formed planet would spur on the evolution of some pretty strange lifeforms, including sea monsters.

Dead Planets Society is a podcast that takes outlandish ideas about how to tinker with the cosmos – from punching a hole in a planet to unifying the asteroid belt to destroying the sun – and subjects them to the laws of physics to see how they fare.

Your hosts are Leah Crane and Chelsea Whyte.

If you have a cosmic object you’d like to figure out how to destroy, email the team at It may just feature in a later episode… And if you just want to chat about this episode or wrecking the cosmos more generally, tweet @chelswhyte and @downhereonearth.
