3. The Planck Epoch Grand Unification Transition
The Planck Epoch is named The grand unification
after Max Planck and is the epoch was the period in the
earliest period of time in the evolution of the
history of the universe. The early universe following the
Planck time is know to be Planck epoch starting at
the shortest possible about 10−43 seconds after
interval of time, and the the Big Bang
Planck epoch lasted only
this brief instant

4. Electroweak phase transition Quark-hadron transition
The third stage after the This comes after the
gran unification was at electroweak phase and this
about 10.11s Electromagnetic is the part of the big bang
and weak nuclear become when the protons, electrons
differenced and hadrons are formed

5. Neuclosynsesis Matter domination
This the stage of the big This is the time when the
bang after the Quark- gravitational instability was
hadron transition and at this first started in the universe,
time the light elements are it also started to become a
formed like Li, He, and D lot cooler then the earlier
stages

6. Recombination Galaxy formation
This is the part of the big Gravitational collapse
bang when the relic happened at this time as
radiation became well as the galaxies we
decoupled. starting to become a
complete galaxies
