A good explanation, Lion. Thank you. As someone has already said, the laws of physics is a major character.
I hope we get to see what life on Mars is like this season or next, and that Mars is as well-realized a place as Ceres.
A lot has been written in this forum about the diversity of the casting. From the perspective of the people inhabiting this universe, I wonder how much the categories of black, white, asian, etc even apply. People are more concerned with whether a person is Earthling, Martian, or Belter. Racism still exists, it has just taken on some new categories.
