Is light slowing down?

Read the latest update. Yes I will defer to the experts, but in my gut I have never bought into the idea that the speed of light should be constant for all space and time. Maybe I am simply too used to economic models, where all the measured magnitudes fluctuate over time. That being said, a faster speed of light in previous times might, among other things, explain why the universe appears to be so uniform. Here is a collection of relevant stories and links.

Get this:

The speed of light, one of the most sacrosanct of the universal physical constants, may have been lower as recently as two billion years ago – and not in some far corner of the universe, but right here on Earth.

Do we economists sound that funny to outsiders?
