The history of the Universe describes a crossover from a scale invariant \"past fixed point\" where all particles are massless, to a \"future fixed point\" for which spontaneous breaking of the exact scale symmetry generates the particle masses. The cosmological solution can be extrapolated to the infinite past in physical time - the universe has no beginning. This is seen most easily in a frame where particle masses and the Planck mass are field-dependent and increase with time.
