It's not about hospitable. It's about survivable. There are large enough meteor strikes where you'd be better off on a self-sustaining Mars colony than anywhere

It's not about hospitable. It's about survivable. There are large enough meteor strikes where you'd be better off on a self-sustaining Mars colony than anywhere on Earth.
- danaris 4y agoUnless you're personally in the strike zone, that's not true. And one should also bear in mind that Mars is at no less risk of meteor impacts than Earth.
- travisjungroth 4y agoIt’s not about Mars being lower risk but independent risk. Someone could decide to keep copies of important documents in their vacation home not because it’s less likely to have a fire, but because it’s less likely for both houses to have a fire. I used the wrong word when I said meteor. They’re too small. A comet or asteroid of 100km diameter would raise the temperature of the surface of the Earth by hundreds of degrees and then there’d be decades of darkness. https://www.sciencedirect.com/science/article/pii/S0016328722000337 https://www.sciencedirect.com/science/article/pii/S001632872...
