Special relativity is a cornerstone of modern physics.  Its most basic  prediction is that there is a maximum speed which any particle can attain.  I will explain how an indirect experimental test of this  prediction has shown that the limiting speeds of different particle types are the same to an accuracy of about one centimeter per century, one quadrillion times more stringent than the claimed detection of  faster-than-light neutrinos made by an Italian physics collaboration two years ago (a result later found to be in error).
