Diagram of a Wormhole and Quasar. Wormholes are hypothetical areas of warped space-time. The high energy contained in a wormhole could create tunnels through space-time. If possible, wormholes would allow a traveler to move through time. Quasars are compact regions in the center of massive galaxies. These surround supermassive black holes.
