Cosmological law of universal gravitation

Cosmological Consequences of Anti-gravitation

The dynamics of a universe with an anti-gravitating contribution to the matter content is examined. The modified Friedmann equations are derived, and it is shown that anti-gravitating radiation is the slowest component to dilute when the universe expands. Assuming an interaction between both kinds of matter which becomes important at Planckian densities, it is found that the universe undergoes ...

Bulk viscous string cosmological models in Saez – Ballester theory of gravitation

Spatially homogeneous Bianchi type-II, VIII and IX anisotropic, as well as isotropic cosmological models can be obtained in a scalar tensor theory of gravitation proposed by Saez and Ballester (1986) when the source for energy momentum tensor is a bulk viscous fluid containing one-dimensional cosmic strings. All the models obtained and presented here are expanding, non-rotating and accelerating...

The epic journey from Kepler ’ s laws to Newton ’ s law of universal gravitation revisited

Gravitation, the Quantum, and Cosmological Constant

The arguments of statistical nature for the existence of constituents of active gravitational masses are presented. The present paper proposes a basis for microscopic theory of universal gravitation. Questions like the relation of cosmological constant and quantum theory, black hole radiance and the nature of inertia are addressed. This paper is the second in the series of papers published in A...

The Cosmological Redshift as a Virtual Effect of Gravitation

“Will the universe expand forever?” (Gott et al. 1974, 1976) This has been one of the main questions of cosmology since the interpretation of the redshifted light of remote stars and galaxies as a Doppler phenomenon was accepted by the majority of cosmologists. Prodigious efforts have been made to estimate the amount of matter in the universe and to determine quantities such as the Hubble param...
