They didn't increase the speed of light, but increased the group velocity of the light pulses. There is a distinction between the two. No actual
particles go faster than the speed of light in that experiment, but the pulse they form together does. Think of it as a point for a laser on earth
shining on the moon moving faster than the speed of light when you move the laser from left to right. The dot goes faster than the speed of light, but
no particle does.
I don't understand why c must change when the fine structure constant is different. Can't h, the planck constant, or e, the charge of the electron,
vary. I don't like the idea of constants varying, especially the speed of light, but if that's what the evidence tells us we need to accept it. It
will not cause that much problems though. A varying c can easily be incorporated in general relativity or electromagnetism. The GUTs will have the
largest problems, because they have to explain why c can change and why it changed the way it did.
BlackJackal, do you understand the difference between the creationists claims that the speed of light was infinite 7000 years ago, which is why we
sees light from distant stars now, and this article's claim that the speed of light varied 4,5 parts in 10^8 billions of years ago?
