sending all Muslims to Mars...hmmmmm
I read it here on FR:
Mars can never be colonized, because the inner core has cooled and unlike the Earth’s core, it is solid and unmoving. Because of this, the gravity is not strong enough to hold the atmosphere to the planet.
So the Heinlein book wherein they had large Oxygen-producing machines just ain’t gonna happen, which is a bummer.
The good news is that the oxygen-free environment makes it a good destination for muslimes.
