In the model, the exchange of gravitons among the dipoles and the potential of vacuum balances the energy of the fluctuation. The effect is to create bubbles of space-time that by growing they expand the local vacuum. The model suggests that the universe originates from overlapping of bubbles of space-time associated with dipoles. Matter is originated during gravitons decay. The use of the Bridge Theory demonstrates how the attractive force field that emerges in each bubble is in the first approximation in accordance with Newtonian gravity at small, medium and large distances in accordance with the theory of General Relativity by also introducing a variable cosmological term that justifies some observed cosmological anomalies. The model overcomes the current concepts of Dark Energy and Dark Mass in favor of a gravity produced by the curvature of space-time of the bubble. The existence of the balancing gravitons provides an estimate of the actual amounts of Dark Energy, Dark Matter and matter measured in the current universe. The estimated theoretical mass of the balancing gravitons is consistent with the Kaluza-Klein gravitons of 2.68 TeV observed in the ATLAS experiment during Run #1. Moreover, the use of the observational data of the rotation speeds of two samples of galaxies allows to verify the good agreement of the real universe with the model, providing a possible explanation of the variability in the measurement of the Hubble constant.展开更多

In this context, it is shown how the space-time fabric of the emerging universe and the primordial matter contained in it, can be considered the final result of the decay of a pre-universe formed by a BEC of neutral Planck bosons hidden under the space-time horizon, having the characteristics of balancing gravitons associated with the potential energy of the vacuum defined as the field of nothingness. The estimated mass of the Planck boson is compatible with the smallest of the Kaluza-Klein graviton with an energy mass of 2.68 TeV, this value allows to estimate the limit of the Planck energy scale characterized by a lepton particle with a rest mass of 1.27 TeV. It is also shown as an ancient multi-bubble universe obtained by the decay of a pre-universe redshifted nowadays at 2.725 K, provides a Planck blackbody spectrum perfectly in agreement with the cosmic microwave background radiation of our universe measured by the COBE satellite.展开更多
