And what if gravity is intrinsically quantic ?

TL;DR

This paper explores the intrinsic connection between quantum mechanics and gravity, proposing that gravity has a fundamental quantum role and offering a preliminary formulation within a finite-particle system.

Contribution

It introduces the idea that gravity is inherently quantum and provides a new perspective and initial formulation for gravity in a quantum universe.

Findings

Quantum mechanics becomes ambiguous without gravity.

Gravity may have an intrinsic quantum nature.

Preliminary formulation for gravity with finite particles.

Abstract

Since the early days of search for a quantum theory of gravity the attempts have been mostly concentrated on the quantization of an otherwise classical system. The two most contentious candidate theories of gravity, sting theory and quantum loop gravity are based on a quantum field theory - the latter is a quantum field theory of connections on a SU(2) group manifold and former a quantum field theory in two dimensional spaces. Here we argue that there is a very close relation between quantum mechanics and gravity. Without gravity quantum mechanics becomes ambiguous. We consider this observation as the evidence for an intrinsic relation between these fundamental laws of nature. We suggest a quantum role and definition for gravity in the context of a quantum universe, and present a preliminary formulation for gravity in a system with a finite number of particles.
