We propose that the early Universe was not Lorentz symmetric and that agradual transition to the Lorentz symmetric phase occurred. An underlying formof the Dirac equation hints to such a transition for fermions. Fermions werecoupled to space-time in a non-trivial manner such that they were massless inthe Lorentz violating phase. The partition function is used as a transfermatrix to model this transition on a two level thermodynamics system thatdescribes how such a transition might have occurred. The system that modelsthis transition evolves, with temperature, from a state of large to negligibleentropy and this is interpreted as describing the transition to a state withLorentz symmetry. In addition to this, analogy is created with the propertiesof this system to describe how the fields were massless and how a baryonasymmetry can be generated in this model.
