  Using Heisenberg's uncertainty principle it is shown that the gravitational
stability condition for a crystalline vacuum cosmic space implies to obtain an
equation formally equivalent to the relation first used by Gamow to predict the
present temperature of the microwave background from the matter density. The
compatibility condition between the quantum and the relativistic approaches has
been obtained without infinities arising from the quantum analysis or
singularities arising from the relativistic theory. The action which leads to
our theory is the least action possible in a quantum scheme. The energy
fluctuation involved in the gravitational stabilization of vacuum space is 10
to the power of (-40) times the energy of the crystalline structure of vacuum
space inside the present Universe volume.
