Not quite. We’d have to get out of Earth first. In a billion years, our Earth would no longer be habitable.
Our best option, according to Ray Villard, news director for the Hubble Space Telescope, is for us to
… come up with a strategy to build artificial mini-planets – essentially flying city-states — that would modify their orbits to migrate along with the petulant Sun’s expanding and shrinking habitable zone. As the white dwarf cools, the wagon train of space habitats would move inward. Raw materials would be harvested from in-falling comets and asteroids. Explorers would be free to travel outward to visit surviving planets and moons. Given our passion for survival, bolstered by super-technology, the future for mankind could truly stretch on indefinitely, beyond even the life of the Sun.
That’s hope for you.
