Concordance of the Dirac-Milne universe
« 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
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. »
