Straight Outta Antarctica: Ice Cube Reports Fastest-Ever Neutrino

A schematic illustration of the IceCube detector array.Image courtesy Phys.psu.edu Astrophysicists from IceCube, a neutrino research facility near the south pole, have just reported the observation of a neutrino moving with a kinetic energy of ~2.6 petaelectronvolts (PeV), roughly enough energy to depress a key on your keyboard.If that doesn't astound you, let's talk numbers for a moment.It doesn't take a lot of work to punch a period at the end of your sentence; it's less than a millijoule of ...
