Abstract |
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. |
