> Also who wants to live in a planet in perpetual darkness? I'd guess in that case people would be living underground in artificially lit environments... This idea has already been explored by sci-fi. One instance that comes to mind is Wandering Earth where the premise is that people turned the Earth into a planet scale space vessel to escape the sun's expansion and "rehome" the Earth. I'd suggest reading the book rather than watching the movie based on it though.
