Big bang Quote by Henning Genz

““We recall that the term inflation stands for the explosive growth of the universe by a factor of 10^50 in the time span between t = 10 ^-36 and t = 10 ^ -33 seconds. This is the time sequence suggested by the original Big Bang model but does not necessarily depend on it. In our present context, it is important to see what triggered the inflationary expansion. The models we mentioned have a vacuum state of our world pass from a symmetric phase into one with reduced symmetries. At the onset of inflation, some 10^-36 or 10^-35 seconds after the Big Bang, the initial era of the universe, when all the forces had the same strength, has long since passed; that ur-state had held only until t = 10^-44 seconds. Tryon's model includes the possibility that no matter at all existed before the onset of inflation; there was only empty space, but all the laws of nature did exist. In the model of Hartle and Hawking, inflation simply follows what they call the Planck time, the time at which quantum mechanical uncertainty also included space and time. It is at that time that the symmetry of the TOE, the theory of everything, collapsed. Now back to the start of inflation at t = 10^-36 seconds: Up to it, and ever since the Planck time, there have been two forces-gravity and the unified forces of the elementary particles. All particles shared mass zero at the onset of inflation; all forces shared range infinity. The universe was, at a temperature of 10^28 degrees- sufficiently cold to permit the crystallization of a preferential direction in the abstract space of particle properties. This is analogous to the emergence of a direction of magnetization, as we discussed above-with the one difference that we have generalized geometric space to an abstract space.””
