Wormholes

            The wormholes were mathematically studied before scientists took black holes seriously. A problem is they don’t stay open very long. They stay open for a tiny fraction of a second. If you get sucked in one you will get trapped because it will probably close right when you get in. if you get through you would have to travel faster than light. The wormhole would be unstable. If they stayed open longer and did not make objects travel at speeds faster than light, then time travel might be possible. Einstein’s equations describe a wormhole that connects two regions of flat space time, two universes, or two parts of the same universe. Before light can go from universe to universe gravity will close the wormhole (door between universes.) if you use electricity you might be able to keep the wormhole open long enough to travel through it. If you go into one you will have an extremely hard time getting back to tour own universe. This makes us wonder if it will be possible.
