Galaxies come in only a few shapes, which are all very round looking. You’ve got spirals and you’ve got blobs. Not content with this boring assortment, Leah Crane and Chelsea Whyte want to shake things up a bit.
First up they want to give our own spiral galaxy, the Milky Way, more arms. One, two… eight? As many as possible. But they don’t stop at “octogalaxy”. They also ponder on what it would take to defy the laws of physics and create a giraffe-shaped galaxy.
Aided by Vivian U, an astronomer at UC Irvine, the team discusses whether smashing galaxies together would help in their quest, how shooting black holes into orbit via rail gun may create interesting patterns and whether the galaxy sculpture can be made using dark matter.
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.
