Nous rappelons les bases d'une théorie champ moyen récemment développée pour la gravitation relativiste. Un lissage particulièrement simple de l'espace–temps de Schwarzschild est proposé en tant qu'exemple. Nous utilisons ensuite cet exemple pour discuter des observations actuelles et futures de .
We review the basics of a newly developed mean field theory of relativistic gravitation. A particularly simple coarse graining of the Schwarzschild space–time is presented as an example. We then use this example to discuss current and near future observations of .
