What is Grand Unification Epoch???
It is the second
stage in formation of universe as per the Chronology of our universe. In my
previous article, I explained about the Plank Epoch, which is the previous step
of Grand Unification Epoch. So, if you haven’t that article yet, then I highly
recommend you to read that article first so that, you can understand this
article more efficiently.
Grand Unification
epoch was from 10^-43 seconds to 10^-36 seconds. It is believed that gravitational
force was separated from the grand unified force while other forces remained
unified as electronuclear force.
As per our current
understanding, the characteristics like mass, flavour and charge were
meaningless at that time period. It is also believed that, around this
time-period the creation of earliest elementary particles and their antiparticles started.
During this
period, the universe was still extremely hot and small. But it was cooled
enough for the separation of gravity. When gravity was separated, only a single
unified field remained which is described by Grand Unified Theory.
We cannot find
this field today as back at that time all the current fundamental forces except
Gravity were unified but, today the other three fundamental forces: strong
nuclear force, Weak force and Electromagnetic force are separated and working separately.
Grand Unification epoch is followed by Inflationary epoch as per the Chronology of our Universe.
