In this video Dr Hannah Wakeford and I combine our atmospheric and planetary physics PhD skills to review planets from Games Workshop's Warhammer 40k to see which ones could really exist in our galaxy! We review Cadia, Istvaan III, Catachan, Barbarus, Tinek'la, Titan, and Mars. One of these is Hannah's absolute favourite world. One of them is perfectly balanced with no exploits.

Scientists use science to review planets in warhammer 40k, also known as warhammer 40,000. With ninth edition coming up, what better time to review the planets? 9th ed holds many surprises, but we doubt it will make any of these planets more possible. No number of command points will save Tinek'la or Barbarus from planetary physics! Thanks again to Spiffing Brit for bringing some perfectly balanced tea drinking and to Rimmy from the yogscast for his Catachan charms via their voices. Also apologies if you like T'au but let's face it - you're a bit of a weeb.
