Darwinian quantum gravity cosmic inflation

Abstract

Recent experimental data indicates that of the several approaches to Cosmic Inflation (CI), the most adequate approach is Starobinsky Inflation (SI) which uses a Jordan Frame (JF) where the gravitational constant depends on the quantum fields (QFs), which when transformed into an Einstein Frame (EF) obtains an Inflaton Field (IF) $\varphi$. To consider the role of decoherence in the IF $\varphi$, a Darwinian Quantum Gravity perspective called Physics-Cell (PC) approach is considered. In the PC approach, the physics occurs through a QF array $\Psi$ within a 3D time-free medium through the emission and transmission of two types of QFs between PCs, QF array $\Delta \Psi$ and QF scalar $\delta \Psi$. The $\Delta \Psi$ are sent from the PCs based in the rules of the Standard Model of Physics (SMP) calculated within the PCs, the $\delta \Psi$ is associated to the communication of the correction necessary to cancel the effects of the non-infinitesimal value of the PC time-step, and we propose here that $\delta \Psi ≔\varphi$. The energy density of $\delta \Psi$ is equal to dark energy’s density thus the IF $\varphi$ energy density is the dark energy, which agrees with other works suggesting likewise. In PC approach, the gravitational effects occur through the transmission of the communication protocols between PCs by the averaging of $\Delta \Psi$ correlations. This PC approach to CI obtains a reason for both start and end of CI, does not require initial conditions fine-tuning and has an approach to decoherence compatible with contemporary physics’ Quantum Darwinism.
