On the Principle of Relativity of Inertia in both General and Entangled Relativities

TL;DR

Entangled Relativity is a new, economical theory that unifies aspects of General Relativity and quantum field theory, emphasizing matter's inseparability from spacetime.

Contribution

It introduces Entangled Relativity, a novel framework that recovers existing theories and aligns with Einstein's vision, emphasizing matter's fundamental role in spacetime.

Findings

Recovers General Relativity and quantum field theory in specific limits

Precludes matter-free spacetime regions

Offers a more economical and conceptually unified approach

Abstract

Entangled Relativity is a novel theory of relativity that offers a more economical approach than General Relativity. It successfully recovers both General Relativity and standard quantum field theory within a specific (yet generic) limit. Furthermore, Entangled Relativity precludes the existence of spacetime devoid of the matter that permeates it. Consequently, I argue that Entangled Relativity is not only preferable from the standpoint of Occam's razor, due to its economical nature, but it also aligns more closely with Einstein's original vision for a satisfactory theory of relativity.
