Description
Several attempts have been made over the decades to integrate gravity into the Standard Model of the elementary particles, the most notable being the AdS/CFT gauge-gravity scenarios. However, none of these attempts have yielded satisfactory results. In this work, a novel BSM (Beyond Standard Model) theoretical framework is introduced to describe a possible integration of gravity into the standard model. In this framework, the constant of universal gravitation, and the vacuum energy are significantly higher at the start of the universe, up to the end of the quark-gluon phase. Once quarks get confined into hadrons, the high gravitational and vacuum energy effects become trapped inside the strongly interacting particles and no longer have any influence on spacetime. This scenario is shown to shed new light on the dark energy problem, as well as on the ‘cosmological constant’ discrepancy. Further, gravitational waves produced during the early expansion phase in our model are shown to have a unique signature and may be detectable as part of the primordial Stochastic Gravitational Wave Background using pulsar timing arrays.
