Thanks, and I agree — but also, conditions on Earth have changed, rapidly, so many times, that the foolish idea that everything has been uniformly and barely changing is egregiously in error.
I think on this sort of thing and build planetary systems in my head at night to deal with insomnia. The possibilities really are as limitless as imagination.
One of my favorite thoughts is about a planet in close orbit with a white dwarf. The planet tidally locked so one side faces the dwarf all the time but the dwarf/planet system orbit a large star.
The planet would actually have a day night cycle on the “dark side” but it would be due to it’s orbit around the dwarf star.
