In 2006, Alan Kogut and his colleagues from the Goddard Space Flight Center, searching for signs of heat from the first generation of stars with the balloon-borne Arcade 2 equipped with sophisticated radiometers, discovered instead an intense radio emission that nobody had still detected, that no physical model had foreseen the existence, and which results from none of the known sources in the Universe. This cosmic background noise has an intensity of synchrotron emission estimated six times higher than the combined radio of all radio sources in the known universe. Our hypothesis is that this radio emission of extragalactic source is the residue of a huge energy burst soon after the recombination, triggering simultaneously the formation of first stars and the reionization. Under the theory of Relation, it is the vestige of a sudden release of energy from a relativistic bang, via a Lorentz energetic transformation, which fills an energy-matter deficit, and generates both the birth of primordial stars and the reionization of neutral gas. This extra ordinary matter would replace the hypothetical cold dark matter theorized to be the missing primitive matter initiating large structures.
