Are they also inertialess? Being immune to gravity won’t make them just stop; stop, relative to what?
So, they continue in a straight line, while their body moves in rotation with the Earth’s surface × orbit around the sun × orbit around Sagittarius A × whatever movement the Milky Way is making based on the local cluster… I wonder how much angular movement the supercluster is making.
I think the inertia question would affect the velocity of the ghost relative to the rest of the planet. But unless the ghost has the necessary movement powers to maintain their position, I have to think the earth’s path versus the ghost’s straight line through space would diverge pretty quickly.
Interesting to think about, especially in light of the other reply discussing the hypothetical of ghosts being able to choose & switch frames of reference.
Honestly though, since just about everything is affected by the way gravity bends spacetime, including light, I bet they’d stay with the earth. Maybe just have to hover above the surface in order to not fall down to the core of the planet.
