    If she is still affected by gravity, but passes through matter, she would immedietly fall through the floor and start orbiting the earth through the planet.

    Without gravity she would no longer follow the earth’s/sun’s/etc. orbit.

      but the question is what would determine the trajectory then, there is no universal arbitrary straight line, that’s a concept that just doesn’t make sense under physics as we know it.

      Even massless particles gain an effective mass and thus interact with gravity/spacetime; according to everything we’ve observed and calculated so far the only sensible result is acting like light does, and weakly interacting with gravity.

        Well, yea, idk how moving through spacetime without following it’s curvature would makes any sense. Which is what gravity is. Meaning the comic makes no sense.
