The Planck Epoch is best described as the non Fermion String nucleus Big Bang. of Q-FFF Model. Each quark is build out of 2,3 or 4 transformer strings. able to transform by the internal rotation of the 3 hinges of a little string torus called the oscillating Axion string, being the Dark Energy of the vacuum fluxtube lattice. SO at the moment t=0 the big bang was a dense knot of strings, compressed by the decreasing pressure of the Big Crunch of our former universeor even called raspberry multiverse of Quantum Function Follows Form theory. (Q_FFF).
