Gravity as the affine Goldstone phenomenon and beyond

TL;DR

This paper proposes a novel theory where gravity emerges as a Goldstone boson from a spontaneous phase transition, extending relativity principles and introducing the concept of a Metauniverse with multiple regions of metric phases.

Contribution

It introduces a new framework for gravity as an affine Goldstone phenomenon and develops the theory of metagravitation within a nonlinear model based on GL(4,R)/SO(1,3).

Findings

Gravity emerges as a tensor Goldstone boson.

The theory extends relativity with the principle of metarelativity.

Introduces the concept of a Metauniverse with multiple metric regions.

Abstract

The two-phase structure is imposed on the world continuum, with the graviton emerging as the tensor Goldstone boson during the spontaneous transition from the affinely connected phase to the metric one. The physics principle of metarelativity, extending the respective principle of special relativity, is postulated. The theory of metagravitation as the general nonlinear model GL(4,R)/SO(1,3) in the arbitrary background continuum is built. The concept of Metauniverse as the ensemble of the regions of the metric phase inside the affinely connected phase is introduced, and the possible bearing of the emerging multiple universes to the fine tuning of our Universe is conjectured.
