It is a joke, right? It's so full of scientifically sounding nonsense that it's almost believable.
The only problem is this guy (the journalist) has obviously never learnt basic logic to jump to conclusions almost FTL

.
In research carried out in the United States, particle physicists have shown that light pulses can be accelerated to up to 300 times their normal velocity of 186,000 miles per second.
The implications, like the speed, are mind-boggling. On one interpretation it means that light will arrive at its destination almost before it has started its journey. In effect, it is leaping forward in time.
Where the heck did this conclusion come from? "Almost before"? It sounds like "somewhat pregnant"

.
References to "caesium gas" (it's a metal) and "photons — the particles of which light is made" (light is EM waves) make me understand what happens when people study Science at school

In good ol' days we had physics, chemistry etc taught separately

. Then again - whatever keeps one amused...
