Mach’s Principle and a Variable Speed of Lighting hypothesis of Sciama (1953) on the gravitational constant, c./G = ∑ m./r., is linked to Dicke’s (1957) proposal of an electromagnetic origin of gravitation, a precursor of scalar-tensor-theories. A formula for c depending on the mass distribution is given that reproduces Newton’s law of gravitat

A Century of Cosmologyross to an observed horizon about 30 Gpc across that is only a tiny fraction of an immensely large inflated bubble. The expansion of our knowledge about the Universe, both in the types of data and the sheer quantity of data, has been just as dramatic. This talk will summarize this century of progres

Spherically Symmetric, Static Spacetimes in a Tensor-Vector-Scalar Theorytion while in the second the vector field has a non-vanishing radial component. The Parameterized Post-Newtonian (PPN) coefficients are calculated for these cases. For the first branch of solutions, I derive exact analytic expressions for the physical metric and apply them to the case of black holes. Implications are discussed.

Type Ia Supernovae and Cosmologyomparison with observations and show in a preliminary approach, how such a model can be applied to study the origin of the diversity of SNe Ia which could be a source of considerable systematic errors in their distances.

Structure Formation in a Variable Dark Energy Model and Observational Constraintsn in a parameterized dark energy model, and compare its predictions with recent observational data, from the Supernova Ia gold sample and the parameters of large scale structure determined by the 2-degree Field Galaxy Redshift Survey (2dFGRS), and put some constraints on the free parameters of this model.

Conference proceedings 2007year 2005, which marked the 100th anniversary of the ‘annus mirabilis‘, that year in which Albert Einstein published three of his most important scientific papers, was the perfect opportunity to review and to present the current scientific understanding of relativistic topics including cosmological
