Could We Move Planet Earth Across the Universe?
Season 9
Episode 15
Interstellar travel is horrible and deadly. Much safer to stay on here Earth with our gloriously habitable biosphere, protective magnetic field, and endless energy from the Sun. But what if we could turn our entire solar system into a spaceship and drive the Sun itself around the galaxy? Well, I don't know if we definitely can, but we might not not be able to.
