According to a recent study (OR POSSIBLE GOVERNMENT CONSPIRACY), time travel is effectively impossible as a result of photons being unable to travel faster than light. But what about photons shot out of a cannon? "You're an idiot." Am I? *staring into laser beam*
By proving that even a single photon must obey Einstein's theory that nothing can travel faster than the speed of light, Hong Kong physicists believe they have debunked the idea of time travel once and for all.
A Hong Kong University of Science and Technology research team led by Du Shengwang said they had proved that a single photon, or unit of light, "obeys the traffic law of the universe."
"Einstein claimed that the speed of light was the traffic law of the universe or in simple language, nothing can travel faster than light," the university said on its website.
If Shengwang and his team are correct, that possibility is now no more than ancient history.
Pfft, that doesn't prove anything. Who the hell wants to send A SINGLE PHOTON back in time?! I want to send all 260-pounds of me! "You're missing the point. If you can't send a single pho-- you know what? Just forget about it." I already have. *doodling picture of a dinosaur with a tramp stamp*
Thanks to Vance, algo and Matt, who agree it's not the size of your time machine, it's how you fiddle with the knobs.
