Dead Planets Society: #10 Cube Earth Part One
This is it, the moment we’ve all been waiting for. We’ve killed the sun, smushed the asteroid belt, burrowed into other planets… but now it’s time for the big one… Earth.In this two-part season finale, Leah Crane and Chelsea Whyte do irreparable damage to our planet by turning it into a cube. Joining the pair in this mammoth task is geophysicist and disaster consultant Mika McKinnon. In this first episode Mika tackles the many life-changing knock-on effects of cubifying Earth, such as how only portions of the planet would be habitable, why we would need giant fish bowls on wheels to cross from one face to the other and why earthquakes would become the new normal.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 deadplanets@newscientist.com. 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. Hosted on Acast.
