Standard Model elementary particle masses daily life
now abundance of chemical elements Big Bang’s afterglow Big Bang
Origin of particle masses? Newton didn’t know – neither do we … How did the Universe look directly after the Big Bang? Observe it! What is the Universe made of? We barely know 4%! Where is all the antimatter? Universe ought to be symmetric!
