"Hong Kong physicists say they have proven a single photon cannot travel faster than the speed of light. This demonstrates that time travel is impossible, they say."

I think a Timelord somewhere might want to have a word with them...

If a respected and eminent scientist says something is possible, he is almost certainly right.
If the same eminent and respected scientist says something is impossible, he is almost certainly wrong.
Can't remember who said it first, but it's worth remembering.

Also ' a single photon cannot travel faster than light' is a little like saying a car cannot travel faster than itself; it tells us nothing to which I don't say "Well, Duh!"
