Title: Where were the electrons before the big bang?
Post by: jeffreyH on 22/06/2019 14:24:26

I read a lot about quark gluon plasma as a source of the big bang but never about what state electrons were in at the big bang event. Can someone enlighten me?

Please see: https://en.m.wikipedia.org/wiki/Leptogenesis_(physics) (https://en.m.wikipedia.org/wiki/Leptogenesis_(physics))

During the earliest stages of the universe, the fundamental forces were unified into a single force( or at least were all of the same strength).  This means that they did not even exist in forms that they have today.  As the universe cooled, different forces separated out from that mix, one by one. First gravity, then the strong force...   Thus when the "quark soup" was in sway, the electromagnetic force had yet to come into existence as a singular force, so the entity we now call the electron wasn't possible.
To use an analogy, its like when you freeze water.   It doesn't really make sense to ask what "form" or shape the crystal structure of ice took before the water started to freeze, as the crystals depend on the water having the properties to allow them to form.

That is the best response I have heard yet.
