GENERAL RELATIVITY THEORY OF GRAVITATION AND EXPERIMENTS

Bulk Viscous Bianchi Type VI0 Cosmological Model in the Self-creation Theory of Gravitation and in the General Theory of Relativity

In the second self-creation theory of gravitation and in the general theory of relativity, Bianchi type VI0 cosmological model in the presence of viscous fluid is studied. An exact solution of the field equations is given by considering the cosmological model yields a constant decelerations parameter q=constant and the coefficients of the metric are taken as A(t)=[c1t+c<su...

A Unified Theory of General Relativity of Gravitation and Electromagnetism. Iv.

It being required that the determinant g of gij be different from zero, and in fact negative, a contravariant symmetric tensor giJ is defined by g'Jg,, = Vk, where 4Vk is the Kronecker delta, and where a repeated superscript and subscript, as i in this case, means the sum as the index takes the values 1 to 4. This notation holds throughout the paper. For any coefficients of connection rijh, sym...

Gravitation in Flat Space-Time and General Relativity

A covariant theory of gravitation in flat space-time is stated and compared with general relativity. The results of the theory of gravitation in flat space-time and of general relativity agree for weak gravitational fields to low approximations. For strong fields the results of the two theories deviate from one another. Flat space-time theory of gravitation gives under some natural assumptions ...

Another Glance at the Rainbow Y? General Relativity and Gravitation

In ationary cosmology predicts the generation of both density perturbation and relic gravitons. Tests of these predictions, especially the relic gravitons, will be very crucial to the veri cation of in ation. E orts have been made to distinguish di erent in ation models using observed anisotropies of the cosmic microwave background radiation. However, the fact that both scalar and tensor modes ...
