Space stations are the answer. I’ll take a good’ol death star any day over mars.
What would be the mass of a real death star? All metal the size of a small moon? Would it create it's own gravity. Where would we get all the metal that would be needed? It it came from earth, would that affect the mass of our own planet, gravity, rotation, etc.? I've had these questions since I saw Star Wars for the first time. LOL
