By Valerie Jamieson (Image: Fermilab) It is one the biggest mysteries in physics – where did all the antimatter go? Now a team of physicists claims to have found the first ever hint of an answer in experimental data. The findings could signal a major crack in the standard model, the theoretical edifice that describes nature’s fundamental particles and forces. In its early days, the cosmos was a cauldron of radiation and equal amounts of matter and antimatter. As it cooled,
