The particles in the early Universe painted a different picture

Today’s Standard Model describes our Universe’s particles and forces. Although there are many similarities and differences within the Standard Model: between quarks and leptons, between fermions and bosons, between particles and antiparticles, etc., displaying the Standard Model’s particle content in this fashion is oversimplified. The six quarks can take on three colors each and all have fractional charges. The tau, muon, and electron are charged leptons, while the three neutrinos are uncharged. Quarks and leptons have antiparticle counterparts, but of the bosons (on the interior), only the W comes in two types: W+ and W-, which are each other’s antiparticle. Credit : Symmetry Magazine Six quarks, six leptons, and antiparticles comprise the fermions. The quarks, antiquarks, and gluons of the Standard Model have a color charge, in addition to all the other properties like mass and electric charge. All of these particles, except gluons and photons, experience the weak interaction.…
