🧵 Gravity

I'm no expert, I'm not an astrophysicist, or a biologist of any kind. What I don't understand is, why do people genuinely think that planetary colonies are a good idea? Like why do people think it's a good idea to have long term human settlements on the surface of Mars? I ask this because if I'm correct Mars has like 35-40% the gravity that Earth has. In the case of humans gestating in this environment would not really be viable would it? I imagine it would have several complications be they muscular, skeletal, cardiovascular, etc. even then, if they managed to survive, humans that exist in that environment wouldn't ever be able to feasibly come back to earth would they? Imagine if your body suddenly had to exist in something like 2.75*gravity. Your muscles, body fat, skeletal system, cardiovascular system, everything would be under such unbearable pressure I doubt anyone would really be able to survive that. I might be missing something, but like, why do people act like this is a good idea when something like O'Neil cylinders would allow for an artificial force like gravity to exist in the vacuum of space.
