Comment on Portal Paradox

  It’s the scene with the lasers innit? So many “paradoxes” are solved with the answer of “portals cannot move relative to one another,” and then they do the bit with the laser. -_-

  The thing is, movement is relative. Everything on earth is constantly in motion if you’re observing from any other celestial body, so motion itself can’t be what breaks portals. What it might be, though, is acceleration. Those panels in the video seem to be moving at a constant speed, so aren’t experiencing any substantial acceleration, making a portal on them possible

    you can say they cant move ‘relative to each other’, but what about the universe supposedly expanding?

      The same reason the Earth or your body isn’t expanding along with the universe - gravity is stronger than the expansion rate

  They can move at a constant speed in a constant direction, but the acceleration would break them.
