I couldn’t help myself and had to make another Usain Bolt cartoon, but this time I teamed him up with our latest subatomic particle friend, Higgs Boson. Higgs is not known for his speed, unlike our friends the photon and neutrino, but perhaps his life span is the more impressive aspect. The Higgs’ mean life span is a measley 1 zeptosecond (10−21). No wonder physicists have found him to be so elusive in nature!
