From maximum force to physics in 9 lines and towards relativistic quantum gravity

TL;DR

This paper presents a concise 9-line summary of fundamental physics that unifies general relativity and the standard model, offering insights into quantum gravity and proposing key tests for future theories.

Contribution

It introduces a minimalistic 9-line framework that encapsulates all current observations and guides the development of a complete relativistic quantum gravity theory.

Findings

The 9 lines describe all known observations exactly.

They suggest the microscopic constituents cannot be described by a Lagrangian.

They specify decisive tests for quantum gravity proposals.

Abstract

A compact summary of present fundamental physics is given and evaluated. Its 9 lines describe all observations exactly and contain both general relativity and the standard model of particle physics. Their precise agreement with experiments, in combination with their extreme simplicity and their internal consistency, suggest that there are no experimental effects beyond the two theories. The combined properties of the 9 lines also imply concrete suggestions for the microscopic constituents in a complete theory of relativistic quantum gravity. It is shown that the microscopic constituents cannot be described by a Lagrangian or by an equation of motion. Finally, the 9 lines specify the only decisive tests that allow checking any specific proposal for such a theory.
