## On the Cold Big Bang Cosmology and the Flatness Problem

**Authors:** Armando V.D.B. Assis

In my papers \cite{Assis1} and \cite{Assis2}, I obtain a Cold Big Bang Cosmology, fitting the cosmological data, with an absolute zero primordial temperature, a natural cutoff for the cosmological data to a vanishingly small entropy at a singular microstate of a comoving domain of the cosmological fluid. Now, in this brief paper, we show the energy density of the $t$-sliced universe must actually be the critical one, following as consequence of the solution in \cite{Assis1} and \cite{Assis2}. It must be pointed out that the result obtained here in this paper on the flatness problem does not contradict the solution in \cite{Assis1}, viz., does not contradict the open universe, with $k=-1$, obtained in \cite{Assis1}, since the solution in \cite{Assis1} had negative pressure and negative total cosmological energy density, hence lesser that the critical positive density. The critical density we obtain here is due to the positive fluctuations I previously discussed regarding the Heisenberg mechanism in \cite{Assis2}. Hence, the energy density due to fluctuation turns out to be positive, the critical one, this being calculated in \cite{Assis2} from the fluctuations within the $t$-sliced spherical shell at its $t$-sliced hypersurface, being the total energy density that generates the fluctuations, actually, negative in \cite{Assis1} and \cite{Assis2}, hence, again, lesser than the critical one and supporting $k=-1$. These results are complementary and support my previous results.
