The mass of a neutrino is about 0.44x10<sup>-36</sup>kilograms.  (Normally all of these things are measured in more convenient units such as Giga-electron-Volts, but that makes implicit use of E=mc<sup>2</sup>.  If we don't accept that, we have to do the calculations under classical physics, using SI (meter/kilogram/second) units.)  The neutrinos were accelerated to an energy of about 17GeV, or .27x10<sup>-8</sup>Joules.  Using the classical formula <math>\mathrm{E} = \frac{1}{2}mv^2</math>, we get v=110x10<sup>12</sup>meters per second.  This is about 370,000 times the speed of light.

Several scientists have gone on record stating that the neutrinos, which have mass, travel at precisely the speed of light.  This dispoves the [[Theory of Relativity]] and the claim that '''E=mc<sup>2</sup>'''.
