A gravitational theoretical development supporting MOND
Conformal geometry is considered within a general relativistic framework. An invariant distant for proper time is defined and a parallel displacement is applied in the distorted space-time, modifying Einstein’s equation appropriately. A particular solution is introduced for the covariant acceleration potential that matches the observed velocity distribution at large distances from the galactic ...
متن کاملGravitational polarization and the phenomenology of MOND
The modified Newtonian dynamics (MOND) has been proposed as an alternative to the dark matter paradigm; the philosophy behind is that there is no dark matter and we witness a violation of the Newtonian law of dynamics. In this article, we interpret differently the phenomenology sustaining MOND, as resulting from an effect of “gravitational polarization”, of some cosmic fluid made of dipole mome...
متن کاملTesting Bekenstein’s Relativistic MOND with Gravitational Lensing
With the recent elevation of Milgrom’s MOdified Newtonian Dynamics (MOND) to a relativistic theory, the Tensor-Vector-Scalar (TeVeS) theory of Bekenstein, a theory of gravity now exists which does not require dark matter and is consistent with fundamental relativistic principles. However, it remains challenging numerically and analytically to tackle the non-linear equations of TeVeS, which make...

متن کاملThe gravitational deflection of light in MOND
The deflection angle ∆φ of light rays by the gravitational field of a spherical system M(r) is calculated using the MOdified Newtonian Dynamics (MOND). It is shown that ∆φ with an impact parameter r0 can be expressed by the measured rotation velocity v(r) as
