Since the publication of Einstein’s theory of general relativity, a variety of interpretations have been suggested. In 1937, Paul Dirac presented his Large Number Hypothesis (LNH) based on the large difference between gravitational and electromagnetic forces. As a consequence, the energy is proportional to the radius squared and the gravitational constant is inversely proportional to the radius of the universe. The energy increases during expansion, Dirac used the term “additive creation”. The objective is to prove the validity of Dirac’s claims. A new theory, CBU (Continuously Breeding Universe), has been developed. The universe is considered a black hole originating from the single fluctuation of a positron-electron pair. The expansion is driven by the formation of new pairs. The negative gravitational potential energy balances the increase in matter energy. Due to G ~ 1/r, the Planck length
and Planck time
tP depend on the curvature of space. The Schr
ödinger solution of an initial positron-electron fluctuation contains a parameter equal to the Planck length. The CBU theory postulates that the primordial universe undergoes a transition from a black hole to a photon-filled universe. After the transition, one half of the energy is bound to numerous “small” black holes, the seeds for galaxies, while the other half propagates as CMB (Cosmic Microwave Background) radiation. The CMB photons are due to e
+ -e
- annihilations. Characteristically, the CMB photons are pairwise entangled, the radiation loses wave energy but compensates by increasing the photon numbers. According to a new model for black holes, a continuous inflow of matter prevents the black holes from becoming singularities. An energy gap between the event horizon and the inner photon sphere is the source of real matter from a QED vacuum foam. There is evidence that all stellar matter originates from a proton-antiproton outflow from the galaxy central black hole.
