The tests of the constancy of fundamental constants are tests of the local position invariance and thus of the equivalence principle, at the heart of general relativity. After summarising the links between fundamental constants, gravity, cosmology and metrology, a brief overview of the observational and experimental constraints on their variation is proposed.
Les tests de la variation des constantes fondamentales sont des tests de l'invariance de position locale et donc du principe d'équivalence, au cœur de la relativité générale. Après un résumé des liens entre constantes fondamentales, gravitation, cosmologie et métrologie, ce texte propose un état des lieux des contraintes expérimentales et observationnelles sur leur variation.
Mots-clés : Constantes fondamentales, Relativité générale, Principe d'équivalence, Cosmologie, Fond diffus cosmologique, Nucléosynthèse
