The Early Universe and the Standard Model of Particle Physics

Abstract

The most well tested and successful model of particle physics is the Standard Model (SM). It is shown here that the restoration of the full SM symmetry (as in the Early Universe) leads to the result that the electric charge loses all physical meaning and hence does not exist above this scale, As a direct consequence of this we show that `time', `light' along with its velocity c and therefore the theory of relativity, all lose any physical meaning. The space-time structure as known to us, disappears in this phase transition. Thus it is hypothesized that the Universe came into existence when the SM symmetry $ SU(3)_c \otimes SU(2)_L \otimes U(1)_Y $ was spontaneously broken to $ SU(3)_c \otimes U(1)_{em} $. This does not require any spurious extensions of the SM and in a natural and consistent manner explains the origin of the Universe within the framework of the SM itself. Thus the SM, in addition to all its successes, has within itself, the capablity of giving a consistent decription of the origin of the Universe.
