        As I said, there is no “speed” in isolation. Speed is a relative property of an object and a reference frame (i.e. another object, like e.g. a planet)

      To the space outside of the blue portal. Moving the orange portal doesn’t drag the whole surroundings, so assuming both places are on the same planet, the momentum of the box in relations to both places is the same

          Well, it doesn’t in the only source of knowledge we have: the game Portal. I don’t know enough about gravitational forces to have a coherent theory on it, gravitational waves moving through space-time is a bit beyound my real understanding. But in the game if you put a portal on a ceiling, it doesn’t “suck” you until you’re throuth it, so there it isolates gravity somehow.

            If you stick to the premise that the portals exist in a universe with GR, then we can pay much know that space-time is locally flat in and around at least the middle parts of the portal. We know this because things don’t get fucked up when they’re going through.

            At this point, I consider Optozorax’ research the primary source of how portals work. If the games disagree, they’re wrong.
