Key Insights

• 💦 The loss of water on Holy Terra could be possible with advanced geoengineering and atmospheric modifications.
• 😶‍🌫️ Nostromo's extreme darkness is caused by toxic smog and the absence of sunlight due to clouds in the atmosphere.
• ⏰ Tidally locked planets, like Mauryan, can exist and have interesting atmospheric dynamics.

Questions & Answers

Q: Could Holy Terra exist without water?

While the loss of water would have severe consequences on Earth's biosphere and climate, if the process occurred gradually with advanced geoengineering and atmospheric modifications, it could be possible for Holy Terra to exist.

Q: What causes the extreme darkness on Nostromo?

Nostromo's atmosphere is filled with toxic smog, blocking out sunlight and causing the planet to be extremely cold. The clouds in the atmosphere reflect sunlight and trap heat, resulting in a dark and cold world.

Q: Can a planet be tidally locked like Mauryan?

Yes, tidally locked planets are common and occur when one side of the planet constantly faces its star. The habitable band between the light and dark sides could potentially have interesting atmospheric dynamics.

Q: Is it possible for basalt and granite rafts to float on lava on Makar?

It is possible for rocks like basalt and granite to float on lava if there is enough gas in the lava to reduce their density. Coupled with convection in the lava, rock rafts on top of lava lakes, as seen on Makar, could exist.

Summary & Key Takeaways

• The video examines 18 planets and moons in the Warhammer 40,000 universe and analyzes their feasibility based on physical and scientific concepts.

• Planets such as Holy Terra and Nostromo are evaluated for their potential to exist without the presence of warp sorcery.

• Other planets like Valhalla and Armageddon are assessed for their climate and geological inconsistencies.
