 A Wormhole is a theoritical passage through space - time that could create shortcuts for long journeys across the universe.  Wormhole are predicted by the theory of relativity. Wormholes are first theorized in 1916  through that wasn't what they were called at the time. In 1935, Einstein and Physicist Nathan Rosen used the theory of general relativity to elaborate on the idea, proposing the existence of " BRIDGES " through Space - time. Those bridges connect two different points in space - time, theoriticaly creating a shortcut that could reduce travel time and distance. The shortcuts came to be called " Einstein - Rosen Bridges" or " Wormhole" A Wormhole could create extremely long distances such as a billion light years or more, two different universes, or different points in time.   NASA's Eric Christian wro te -  "A Wormhole is not really a means of going back in time, it's a shortcut, So that something that was...

           ASTRONAUT  An   astronaut  or  cosmonaut  is a person trained by a  human spaceflight program  to command, pilot, or serve as a crew member of a  spacecraft . Although generally reserved for professional space travelers, the terms are sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists. [1] [2] Until 2002, astronauts were sponsored and trained exclusively by governments, either by the military or by civilian space agencies. With the suborbital flight of the privately funded  SpaceShipOne  in 2004, a new category of astronaut was created: the  commercial astronaut .
