Titre Concordance of the Dirac-Milne universe
Résumé The Dirac-Milne universe, a matter-antimatter universe where antimatter has a negative gravitational mass, presents several elements of concordance with our universe, except apparently for two tests: primordial helium-3, and BAO, at least if the latter is interpreted in a conventional way. After a discussion on the definition of a negative mass particle, I will describe the formation of structures in the Dirac-Milne universe, as well as some additional studies that can be carried out on this model, in order to further test its concordance with our universe.
