Physicists Prove That Time Travel Is Impossible

Physicists at the Hong Kong University of Technology and Science crushed the dreams of millions of nerds when they published a study claiming that time travel is impossible.

The belief was that if a single photon could exceed the speed of light, time travel was within the realm of what is physically possible. However, Shengwang Du and his team measured the ultimate speed of a single photon and found that it cannot achieve these speeds.

From the LA Times:

“The results add to our understanding of how a single photon moves. They also confirm the upper bound on how fast information travels with light,” Du said in a statement put out by the Hong Kong University of Technology and Science.

“By showing that single photons cannot travel faster than the speed of light, our results bring a closure to the debate on the true speed of information carried by a single photon.”

Will you ever look at Back To the Future or Doctor Who the same way ever again?
