Experimental and observational tests of antigravity
Gabriel Chardin
Whereas repulsive gravity was considered as a fringe concept until the mid-1990's, the growingexperimental evidence since this epoch for repulsive gravity, in what is now called Da…
MOND-like behavior in the Dirac-Milne universe -- Flat rotation curves and mass/velocity relations in galaxies and clusters
Gabriel Chardin, Yohan Dubois, Giovanni Manfredi +2
We show that in the Dirac-Milne universe (a matter-antimatter symmetric universe where the two components repel each other), rotation curves are generically flat beyond the charact…
Structure formation in a Dirac-Milne universe: comparison with the standard cosmological model
Giovanni Manfredi, Jean-Louis Rouet, Bruce N. Miller +1
The presence of complex hierarchical gravitational structures is one of the main features of the observed universe. Here, structure formation is studied both for the standard ($Λ\r…
Gravity, antimatter and the Dirac-Milne universe
Gabriel Chardin, Giovanni Manfredi
We review the main arguments against antigravity, a different acceleration of antimatter relative to matter in a gravitational field, discussing and challenging Morrison's, Good's…
Cosmological structure formation with negative mass
Giovanni Manfredi, Jean-Louis Rouet, Bruce Miller +1
We construct a family of models with negative gravitational mass in the context of Newtonian gravity. We focus in particular on a model that reproduces the features of the so-calle…
Introducing the Dirac-Milne universe
Aurélien Benoit-Lévy, Gabriel Chardin
The ΛCDM standard model, although an excellent parametrization of the present cosmological data, requires two as yet unobserved components, Dark Matter and Dark Energy, for more th…
