| Mar 23, 2015 at 3:29 | comment | added | Jim2B | I agree, a planet's weather systems would preclude any structure surviving millions of years. The only place we know structures survive is on the surface of airless & dead planets/planetoids (e.g. the Moon). Although I agree that with our current state of knowledge we could not build a survivable space habitat for this period of time, imagine a giant space terrarium - filled up with a biosphere, set in motion, and sealed up from the outside. No active maintenance required. This is possible but there would still be problems. How do you keep the human population in check? | |
