Observational constraints on a Dirac-Milne Universe |
|
Abstract |
Faced to the observation of an effective repulsive gravity usually interpreted as a Dark Energy, we introduce the Dirac-Milne cosmology, a symmetric matter-antimatter universe where antimatter is supposed to have a negative active gravitational mass. We briefly present our motivations for this cosmology which presents a linear evolution of the scale factor and does not require Dark Matter, Dark Energy or inflation. We show that for Type Ia Supernovae measurements, Big-Bang Nucleosynthesis and Cosmic Microwave background this model is surprisingly concordant. |
