Time Travel Proven to Be Impossible

Ten years ago, time travel dreams were stoked by a controlled study in which optical pulses appeared to travel faster than light. That buzz was killed when scientists discovered that it was only a visual effect. Still, the velocity of a single photon was unknown, and speculations of time travel were still hotly debated by physicists and scientists. Prof. Shengwang Du and his team at HKUST managed to isolate single photons to test their speed and prove that, yes, Einstein was right all along.

This news should come as a comfort to China, who banned time travel in film and on television last March, on the grounds that history was being treated frivolously, and should not be portrayed as changeable.

Next up for Prof. Du and his team? A controlled study as to whether Freaky Friday could really happen. Well, that’s my suggestion, anyway.
