An epoch is a moment in time from which nature or situations change to such a degree that it marks the beginning of a new era or age. Times on this list are measured from the moment of the Big Bang. WebIn other models, the electroweak epoch is said to begin after the inflationary epoch ended, at roughly 10 −32 seconds. According to traditional Big Bang cosmology, the electroweak epoch began 10 −36 seconds after the Big Bang, when the temperature of the universe was low enough (10 28 K) for the electronuclear force to begin to manifest as two separate … bryan shaw weatherman
