ANTIGRAVITY. “Some authors have argued, notably in supersymmetric theories, that antigravity, meaning here a slightly different acceleration of antimatter with respect to matter in a gravitational field, is possible without implying any dissipation or instability.” https://lnkd.in/daA2SgMy View in LinkedIn

VERY SLOW LOSS. “For a black hole of the mass of our Sun, the evaporation timescale is of the order of 2 × 10(66) years. As we will see, it is mostly in strong fields, such as those occurring near the horizon of black holes, that this antigravity will lead to significant effects.” https://lnkd.in/daA2SgMy View in LinkedIn

Remedios Varo’s special take on reality is surely no stranger than negative mass, antigravity and the quantum world? https://lnkd.in/d583gjzb View in LinkedIn

SPLENDID GIRONA BORN SURREALIST, “Remedios Varo undertook an esoteric artistic path that would lead to the creation of a truly magical art, which would strive for the spiritual awakening of both artist and beholder, countering Breton’s detached approach and current theories of the ‘disenchantment’ of the modern world.” https://lnkd.in/d583gjzb View in LinkedIn

ALTERNATIVES. “There could be other expressions of the Equivalence Principle respecting the spirit of General Relativity but violating maximally its usual expression.” https://lnkd.in/daA2SgMy View in LinkedIn

PROBLEM OF NEGATIVE MASS. “Still we will see that General Relativity does predict gross violations of the Equivalence Principle as soon as negative mass components are allowed.” https://lnkd.in/daA2SgMy View in LinkedIn

TWEAKING RELATIVITY. “Truly enough, as soon as we express general relativity as a metric theory, with a single metric, it is difficult to see how gravity could distinguish matter from antimatter since according to the very formalism of a single metric, all particles must follow the same trajectory.” https://lnkd.in/daA2SgMy View in LinkedIn

VIOLATION OF EQUIVALENCE. “This will lead us to the Dirac-Milne universe, and a possible explanation of the repulsive gravity that we observe in cosmology, called Dark Energy for lack of better comprehension.” https://lnkd.in/daA2SgMy View in LinkedIn

NEGATIVE MASS. “General relativity violates maximally the usual expression of the Equivalence Principle as soon as the existence of negative mass, possibly as virtual constituents of the quantum vacuum, is allowed.” https://lnkd.in/daA2SgMy View in LinkedIn

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
