The standard model of particle physics has been inordinately successful, providing experimental predictions that accurately describe most of our Universe’s forces and fundamental particles. But the model has some glaring holes. It contains no viable dark matter particle, it lacks an explanation for the Universe’s accelerating expansion, and it predicts a Higgs boson mass that is at least triple that measured in experiments. Now, Raffaele Tito D’Agnolo of the University of Paris-Saclay and Daniele Teresi of CERN have developed a model that provides an explanation for the lightness of the Higgs [1]. The duo says that their model, which invokes multiverses, could also explain other conundrums, such as the observed similarity in how matter and antimatter experience strong interactions.
