    There’s no reason for her to move away from the earth unless she’s being accelerated by something.

    Isn’t the Earth accelerated by the Sun’s gravity, while she isn’t anymore? If yes, she would keep going straight while Earth keeps following its circular orbit, which is equivalent to her moving away from Earth.

      again, straight compared to what?

      there is no center of the universe, nor a universal grid that things can reference. one of the most fundamental tenets of astrophysics is that everything is relative and statements like “travelling straight” are simply nonsensical unless you specify what it’s travelling straight in relation to.

        The… Earth and Sun.

        Those are the reference frames.

        You start by traveling with the Earth.
        Gravity “turns off” for you.
        The Earth then curves away as it orbits the Sun.

        You just follow the tangent line.

          Yes, that was my point. I think it aligns good enough with the comics.

      You know…I believe you’re right. If she somehow became totally massless.

      Edit: no, as other people pointed out it doesn’t make any sense that she wouldn’t be “affected” by gravity even with no mass.

        I think the existence of ghosts at all implies at the least some sort of spiritual plane or dimension that they’re partially in, or at the “worst” straight up magic wherein ghosts cannot interact with the physical world, even with gravity.

        Being able to see may be part of that magic or a function of the spiritual plane as well.

        That would, I think, be able to explain the events of the comic.

        If instead we assume ghosts were entirely explainable by science, that could change things. We’d also have to account for the photons interacting with her and letting her see.

        That’s the assumption in my comment: “while she isn’t anymore” accelerated by gravity. I think that’s what we could infer from the trajectory on the comics.
