From maximum force to physics in 9 lines -- and implications for quantum gravity

Abstract

A compact summary of present fundamental physics is given and evaluated. Its 9 lines 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 search for a theory of quantum gravity. Finally, the 9 lines specify the only decisive tests that allow checking any specific proposal for such a theory.
