Document Summary
Quarks are a fundamental elements of protons and neutrons. Early state of the universe is called a quark plasma: (cid:498)glue on(cid:499) plasma of particles there are no protons and neutrons anymore in the early universe (just a few seconds) there are 6 kinds of quarks. Universe is close to second old quarks combine. Protons and neutrons are made up of two quarks the up and down quarks. Any object cannot move faster than the speed of light, but space time can. Expansion can occur faster than the speed of light. Nothing is going on yet in the early universe. Space time there is no restriction on how fast it can expand. Result rapid expansion of the universe false vacuum not in lowest density state but wants to be, some volume if this happened leads to other consequences. Universe stops growing exponentially greater than the speed of light. Energy gets converted into light or subatomic particles= hubble expansion.
