Speed Bumps

So, according to some British scientists, light does go slower then light. Sort of. They say they detected that light slows down a bit, after a while. Of course, this will not remove any paradoxes, only add some. After all, the slowing, as I understand, must be relative to the light speed, not me and you. Hum.

I wonder if it is possible that other constants steer of their course. For example Pi or e. Say, at some point, integral of e^n will no longer be equal to itself + C. Or equation who's only imprecision is Pi would be less exact with respect to what it tries to describe, then the precision of Pi itself.

And maybe light doesn't slows down after all.
