chaosophia218: Wormholes and Time Travel.Since the 1930’s, physicists have speculated about the existence of “Wormholes” in the fabric of Space. Wormholes are hypothetical areas of warped Space-Time with great energy that can create tunnels through Space-Time. If traversable, it would allow a traveller to quickly move through great distances in Space and also travel through time. The difficulty lies in keeping the Wormhole open while the traveller makes his journey: If the opening snaps shut, he will never survive to emerge at the other end. Illustration above shows Goldberg’s idea of Time Travel. We can see a ship entering an enlarged Black Hole and eventually a Wormhole to travel back in time. Time traveller ends up in a parallel Universe. Lining the Wormhole with exotic matter prevents the ship from being crushed by Wormholes’ forces.For years, scientists believed that the transit was physically impossible. But recent research, especially by the U.S. physicist Kip Thorne, suggests that it could be done using exotic materials capable of withstanding the immense forces involved. Even then, the time machine would be of limited use – for example, you could not return to a time before the Wormhole was created. Using Wormhole technology would also require a society so technologically advanced that it could master and exploit the energy within Black Holes. Both general-relativity theory and quantum theory appear to offer several possibilities for travelling along what physicists call a “closed, timelike curve,” or a path that cuts through time and space - essentially, a time machine. A Wormhole would allow a ship, for instance, to travel from one point to another faster than the speed of light - sort of. That’s because the ship would arrive at its destination sooner than a beam of light would, by taking a shortcut through Space-Time via the Wormhole. That way, the vehicle doesn’t actually break the rule of the so-called universal speed limit - the speed of light - because the ship never actually travels at a speed faster than light. -- source link
