Cosmic Background Bose Condensation (CBBC)

Degeneracy effects for bosons are more important for smaller particle mass, smaller temperature and higher number density. Bose condensation requires that particles be in the same lowest energy quantum state. We propose a cosmic background Bose condensation, present everywhere, whith its particles having the lowest quantum energy state, $\mathrm{\hslash }c\mathrm{/}\lambda$, with $\lambda$ about the size of the visible universe, and therefore unlocalized. This we identify with the quantum of the self gravitational potential energy of any particle, and with the bit of information of minimum energy. The entropy of the universe ($\sim {10}^{122}bits$) has the highest number density ($ \sim 10^{36} \ bits / cm^3$)ofparticlesinsidethevisibleuniverse,thesmallestmass,$\sim 10^{-66} g$,andthesmallesttemperature,$\sim 10^{-29} K$. Therefore it is the best candidate for a Cosmic Background Bose Condensation (CBBC), a completely calmed fluid, with no viscosity, in a superfluidity state, and possibly responsible for the expansion of the universe.
