On the nature of the outward pressure in the Universe (II)
  In Plasma Physics the concept of the Debye length \lambdaD is defined. This length gives the size of a volume such that from outside it the inside electrical charges, positive and negative, electrically screen each other. Given the enormous electrical potential that would develop with no screening, we conjecture that the size of the Universe R, as given by the speed of light c and its age t, R \approx ct, cannot be very much lower than the Debye length. It turns out that it is about 1/3 \lambdaD. Hence inside the volume of size ct there is an otward electrical pressure due to the lack of complete electrical screening of the charges. The Universe does not collapse under its own gravitational attraction, and we present the possibility that this is due to the effect of the repulsive forces of these electrical charges. May be there is too some other mechanism. There is strong evidence today in support of the idea that space is not only expanding but doing it in an accelerated way. We find a large number, 5x1060 that converts Planck's unit of mass, length, time, charge e and angular momentum \hbar, into the mass M, size ct, age t, total charge Q and (possibly) angular momentum of the Universe in a scale like way. It defines a black hole of mass M \approx 1056gr., size 1028 cm., characteristic time 5x1017sec, charge Q \approx 3.5 x1061e and maximum angular momentum \Hbar \approx 10121 \hbar which we identify with our Universe. The solution to the Einstein cosmological equations, including an electrical pressure due to the charge Q, is in agreement with the value of the cosmological parameters currently reported. An argument in favour of a hidden value of the curvature parameter {\Omega}k \approx 1 is also presented here.
