We may be able to book our ticket to the future someday — it’ll just be a one-way trip.
In a presentation at the British Science Festival, particle physicist Brian Cox said that time travel is possible but only in one direction.
“The central question is, can you build a time machine? The answer is yes, you can go into the future,” the University of Manchester professor told the audience during his hour-long speech on Tuesday, according to The Telegraph. “You’ve got almost total freedom of movement in the future.”
Cox detailed how time travel to the future is possible under Albert Einstein’s general theory of relativity. Traveling hundreds, or even thousands of years into the future, could be accomplished if someone was traveling at an incredibly fast pace, close to the speed of light.
