In response to the exciting news from an experiment at CERN that neutrinos may be travelling faster than the speed of light, I presented a Christmas Lecture for a general audience in The University of Warwick's Department of Physics.
It begins by introducing Particle Physics: what it's about and where our current knowledge is. Then we focused in on neutrinos, the particles believed to be travelling fast-than-light, before looking at how the OPERA experiment went about measuring their speed. The final few slides were dedicated to discussing the consequences this has for our current understanding of physics, and some of the places it might lead us in the future.
