- bayesian_horse 8y agoO'Neill cylinders don't work on the moon.

- TeMPOraL 8y agoWould be more worried about this eventually happening the other way around. "Aw, Mom, why can't we go live on Earth with Dad?" "Now, Billy, you know your bones and muscles are used to lunar 0.16G, and won't support your body in full 1G. Your heart isn't strong enough for those conditions either."

- pavel_lishin 8y agoYup, also Andy Weir's Artemis, and to a lesser degree Larry Niven's everyone-except-Jinxians.
- TeMPOraL 8y agoAlso the anime Planetes had touched this topic, AFAIR.
- kamaal 8y agoAt this point in time, any mass settlement in space won't involve going down another gravity well. Pulling stuff out of a gravity well is enough work as it is. Mostly you will have people living and working in neighborhoods, in space, just like you have cities and lot of empty unused land between them on earth. Like space cities. Then cluster of space cities, then may be a region full of such clusters etc.
- andygates 8y agoLunar G isn't microgravity. We genuinely don't have the data, which is why this, Eucropis, and subsequent work is a big deal.
- jerf 8y agoYou can still build something that spins at 1G though. It just isn't a cylinder anymore, but something more like a continuous racetrack.

- kamaal 8y agoPretty much any project that involves humans settling in space in itself is a long shot goal by todays terms. Even if you start mining the asteroids any time in the coming decades, it won't be any thing less than a century after that, until you put humans into permanent colonies.
