Enlargement of Planck`s System of Absolute Units

In this paper, we want to make to see the convenience of the amplification of the Planck`s system of absolute units through the introduction of two new constant, the dynamical constant and the permitividad of the vacuum upon rejecting that the electron charge has mechanical dimensions and adopting it as Planck`s charge. We apply these results to clarify the homogeneity and isotropy in the very early universe.
