According to a US publication, during a presentation at the British Science Festival, particle physicist Brian Cox from the University of Manchester, said that time travel is possible only in one direction, the Huffington Post reported.
Cox said that time travel to the future is possible under Albert Einstein's general theory of relativity.
The researcher detailed the possibility by saying that travelling hundreds, or even thousands of years into the future, could be accomplished if someone was travelling at an incredibly fast pace, close to the speed of light.
Cox explained that the theoretical bridge, or shortcut through space-time, proposed under Einstein's general-relativity theory has never been proven to exist and, even if a wormhole were discovered or created, there's no telling whether humans could actually use it to travel through time.
