What if, someday, we decided that our planet's usefulness has come to an end and that humans need to scour space to find a new place to live? But what if, instead of finding a potentially habitable exoplanet like Earth light-years away, we decided to build our own artificial world right here in the Solar System? What kind of technology would we need to manufacture a new planet? Where would we find enough raw materials to build our future world? How long would it take us to finish this planetary construction project?
