Early Particles

In this era, there are lot of photons, some of electrons and quarks. This era is called the baryonic epoch.

Quarks
Quarks have around five types and counting, examples are up and down quarks. These quarks are part of the nucleus, such as the protons and neutrons. There are the charm, the top and bottom and the strange quark, the top quark is the heaviest among all. These quarks can be part of the nucleus, I think, but it can be unknown.

Electrons
There are lots of electron types, the muon is heavier but smaller and tau also. The electrons can appear in atoms, they move very quick and takes about 100 picoseconds to circle an atom, that is really fast, even you cannot see it properly unless you have to slow the time down, but the slower, the person cannot move but moving under a centimetre.

Electrons have a lot of energy than in present day, that's why they move very quick, but due to the size itself, it could bounce back itself since there is an 'edge' of the universe.
