    Eehh objects in motion stay in motion? Does that apply to ghosts? So would the ghosts fly off in straight lines since no longer subjected to suns gravity ??

        I don’t see how. The law of motion for massless things seems to be “must stay in motion at c in a vacuum until smashing into something, slowly turning into something weird as it loses energy due to the expansion of the universe.”

        If we take a cue from dark matter, they could just not interact with the EM spectrum but still have mass

        Massless objects always move at the speed of light (photos are massless). More important here is, that easy is not on a uniform motion, but rotating around sun, which is rotating around… So even if they remain in their last motion, their path would cover from earth… But motion relative to what? The only special frame of inertia is the cosmic background, and that statement is still under debate

          Speed is always considered relative to something. It wouldn’t be too far fetched to consider ghosts to maintain speed relative to the remains of the body of their late life.
