Speed of light slower than we thought? Probably not

One of these things is not the same as the other...

The travel time of a beam of light/photons and the speed of light in a vacuum can be different. Because you can "stop" the beam/photon and re-emit it. A neutrino though is less likely to be interfered with as it is so small and weakly interacts.

Basically, it's the difference in the theoretical limit "my car can do 150mph" and the "but I'm stuck in traffic doing 1mph" limit. :P
