[0906.3174] The Equivalence Principle and the Constants of Nature

Authors: Thibault Damour

Date: 17 Jun 2009

Abstract: We briefly review the various contexts within which one might address the issue of ‘why’ the dimensionless constants of Nature have the particular values that they are observed to have. Both the general historical trend, in physics, of replacing a-priori-given, absolute structures by dynamical entities, and anthropic considerations, suggest that coupling ‘constants’ have a dynamical nature. This hints at the existence of observable violations of the Equivalence Principle at some level, and motivates the need for improved tests of the Equivalence Principle.
