    Yeah the falling down portal does help a lot with explanation imo

    we can measure the speed of my head moving upwards. Wouldn’t you agree?

    Fair point, we can measure that, it would match the speed of the portal falling. It still won’t launch the person as it isn’t transferred but you can certainly measure the speed of the portal using it.

      But now, when you have a moving object (my body) we need a force to stop that momentum. Where does that force come from?
