Scientists have found a way to make light waves travel infinitely fast
qz.comI don't understand the implications of this research. Can anyone enlighten me? Clearly, they aren't saying that light travels faster than the previously determined speed of light in a vacuum. Further, they can't mean that information is being transmitted faster than light.
I think they mean something like this crude thought experiment of mine: I shine a laser pointer (a strong one) at a point on the moon and flick my wrist to point it at a distant point, say 4000 miles away, on the moon. The laser dot on the surface of the moon will travel faster than the speed of light if I am rotating the laser pointer fast enough, which because of the distance of the moon isn't difficult at all. This isn't faster than light travel; it's still photons traveling at the speed of light, but they are just arriving at the moon's surface at very slightly different times.
