Should we A) colonise other planets or B) build habitats in the middle of space, like O'Neill Cylinders and stuff? (lemmy.ml)

Habitats are risky and not as good as planets imo. It would be trivially simply to sabotage one and kill everyone inside. Just vent atmo into space, poison the air/water, and even a accidental fire could kill everyone who doesnt manage to flee.. Planets not so easy. Some of the same attacks work but u can just walk elsewhere.

plus in a habitat your not really thinking of psychological effects. Its been shown for example that humans needs to see big bodies of water regularly to not get stressed out. So youd need to devote significant space onboard to just that. Plus imagine never seeing the mountains again, or a sunset, or the ocean. The earth is intrinsically linked to our evolution and many of its features are far too big to have on a habitat. I mean not to mention all the microbiomes we interact with unknowingly on earth all the time.

While habitats might be an ok solution for some people there are definitely things we will always need a planet for and imo a planet will always be superior in quality of life.
