Some Equations for the External Space and Their Implications on the Inverse Cone Concept and the Geometry of the Physical Universe

In previous works they were proposed a photonic model of the Big Bang [1] and several parameters
derived from the Hubble-Lemaitre equation [2]. Since these parameters result higher than the
classical ones and, otherwise, the General Theory of Relativity does not apply far away the Physical
Universe, in this paper it will be revised the adequacy of such parameters in the external Space and
their influence on the relativistic concept of the cone of time. As well, it will be intended to define the
Physical Universe geometry accordingly to a thermo-dynamical concept of the Big Bang.
