As I understand it, the only thing that can travel at c are:

* photons

* spherical, massless cows in a vacuum

Not sure about cows. I bet a thing traveling at c might not exactly have 3 spatial dimensions.

Agreed ! The "spherical cow", has to first become a circular cow /s

Anything massless travels at c, not just photons.
