Getting raped in the face with science
wait uhm… what kind of portals he asked? The ones of Portal or the ones of Hl1?
I didn’t mean you accelerate like warp speed but you can notice a little “jump” or something when you go out of a portal and there’s this “whoosh” sound. When you put a cube or some other object in two portals that are on the ground you can watch it come in and out all the time and everytime it comes out it speeds a little bit up, becomes slower, falls back in the portal and then repeats.
