A group of physicists at the Hong Kong University of Science and Technology found out that a single photon cannot travel faster than the speed of light in vacuum. The study reaffirms Einstein's theory that nothing travels faster than light, and most sadly, proves the impossibility of achieving the humanity's dream of time travel.
