@why this is implying that the portal is not simply just a fancy door. if you stand on a platform and a big piece of metal with a hole in the middle falls you simply stand there while the hole drops
@vriska but inside that door is another frame of reference that's flying towards you at high speed. when you jump off a train, you feel stationary and jumping down but suddenly hit the ground going forward
@LukeAlmighty @vriska portals in-game are not coded to work like they would according to the game's logic/explanation. that's why they pop portals whenever a surface moves, so the inconsistency can't be seen in-game
