Good question
I don't have the answer, but the expansion of the universe could be a function of higher dimensions or the estimated life of the universe is way off. I read the announcements by scientists and wonder how they were able to focus on only 1 photon and measure its velocity. The earlier experiments alluded to in the article claimed to be able to slow or speed up photons. Without knowing the methodology and criteria, I am not able to say whether the results are valid or not.
I like Steven Wright's question "If you are in your car travelling at the speed of light; if you turn your headlights on, do they do anything?"
