How much energy does it take to move a whole planet? You don't need a daemon primarch, just take a course on Brilliant! https://www.brilliant.org/SimonClark 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 Terra, Nocturne, Mordian, Valhalla, Armageddon, Oliensis, Bakka, Nocturne, Fenris, and Tanith. One of these might be our favourite planet from a sci-fi universe that we've ever reviewed! We did get a bit carried away in our analysis so to keep the video length reasonable we split the video in two.

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 Armageddon or Nocturne from planetary physics! Thanks again to Rohin from MedLifeCrisis for his analysis of Slaaneshi daemon world Oliensis (sorry Rohin, rules of biology just don't apply to the Eye of Terror), and to Rythian from the yogscast and Digby from ZF clan for providing their voice acting skills.
