CONSEQUENCES. “Price also demonstrates that, as soon as negative masses exist, the vacuum will become polarized. While this polarization will go completely unnoticed in weak gravitational fields, such as that of the Earth, in the strong field regime, for example near the horizon of a black hole, the behaviour predicted by general relativity will change dramatically.” https://lnkd.in/daA2SgMy View in LinkedIn

LATER CONCLUSIONS. “But rather obviously, these studies had assumed that matter and antimatter had both a positive gravitational mass. Today, the discovery of a repulsive gravity through observations of SN1a supernovae luminosity distance, called Dark Energy, leads us to be more cautious: indeed, what seemed previously impossible, repulsive gravity, is the major topic of interest in cosmology.” https://lnkd.in/daA2SgMy View in LinkedIn

EARLY CONCLUSIONS. “Glashow et al. “concluded again that even if the primordial universe had succeeded in creating a symmetrical world between matter and antimatter, diffusion of matter and antimatter at their domain boundaries would lead, as soon as the Universe becomes transparent, to an annihilation between matter and antimatter in conflict with observational limits, unless the domains of matter and antimatter had a size exceeding several billion light-years, which seems unrealistic.” https://lnkd.in/daA2SgMy View in LinkedIn

INCONSISTENCY. “Indeed, if matter and antimatter have both positive gravitational masses and respect the equivalence principle, matter-antimatter annihilation continues to occur after the Universe has become transparent, leading to a diffuse high energy gamma-ray background, already difficult to justify in the early 1970s, at the epoch of the SAS-2 satellite, and clearly inconsistent with the much more sensitive contemporary satellites, such as the Fermi satellite.” https://lnkd.in/daA2SgMy View in LinkedIn
