There are infinite paralell universes, but the Aperture Science Handheld Portal Device is so technologicaly advanced, that it hapens to teleport you, by scrambling your molecules, from one preset area in the first universe (portal#1) and de-scrambles your molecules when you exit the second preset area (portal#2). The infinite universes are everywhere, but as I said ,the "portal gun" is so advanced that against all odds, it teleports you through space, but not time, and sends you back into the same universe/dimension. Of course, all in a mater of less than 5.16 miliseconds. OR- U go in dat wun, u come out dis wun.
