摘要

A new concept has been proposed and elaborated to account for recent observations deviating from ΛCDM and ΛWDM. Using an intermediate energy conversion mechanism in the expanding universe and assuming three neutrino families with identical mass, a neutrino mass of eV/c2 has been found as well as a natural explanation for the difference in Hubble constant as measured by WMAP/Planck and obtained from LSS data. The value for the effective number of neutrinos at the time of decoupling is compatible with the Planck result. The age of the universe is slightly younger at Gyr. At late times, the closure parameter for the neutrino radiation drastically increases but still remains well below that of the baryons , among other energy contributions.
