Will be possible in the far future to create an artificial Moon for Earth and terraformed planets? Will be possible in the far future to use megascale engineering to create an artificial hollow moon to give Earth a big moon in the sky like in billion years ago? Since it would be hollow, it would not have surface gravity (this is what people say), so tides would not be a problem. Am I right? If Ma... (more) |

Will be possible in the far future to use megascale engineering to create a ringworld around Earth? I mean in the far future megascale be advanced enough to allow the construction of a ring world around Earth or around a low mass star( a red dwarf for exemple). If yes, how big Earth would look from the ringworld?And how big and thick the ringworld would look seen from Earth? How day and night cyc... (more) |
