Black hole breakthrough as portal ‘wormholes’ could be shortcuts across universe

Since the early 20th century, physicists have fantasized about deep space travel involving shortcuts through the very fabric of and time (spacetime). These theoretical wormholes, or portals between two , would allow spacecraft to bypass the vast distances between celestial bodies by bridging two separate points in the universe. In theory, this would allow a spacecraft to cover cast distances in a much shorter period of time and possibly allow for some basic time travel.
