The Physics of Portal



The once popular game "Portal" was set in a laboratory where the player used a special gun that shot portals in order to navigate obstacle courses. The gun shot 2 portals, a blue and an orange, that linked together. The player is then able to jump through the first portal and end up where the second one was shot, covering a huge distance. Even complex things such as jumping through the first portal, then firing the second portal immediately afterwards to then fall through the second and back into the first. Though we do not have this technology YET, there are theoretical physics that explain the existence of wormholes. A wormhole is essentially a folding over of the fabric of space-time, so that the same location in space can be reached while traveling almost no distance compared to the original. It is much easier to explain this visually, and this scene from Interstellar does a fantastic job.
