According to Einstein, General Relativity contains the essence of Mach’s ideas. Mach’s principle can be summarized by stating that the inertia of a body is determined by the rest of the mass-energy content of the universe. Inertia here arises from mass-energy there. The latter, was a statement made by John Wheeler in his 1995 book, Gravitation and Inertia, coauthored by Ciufolini. Einstein beli...

Abstract Exponentially expanding space–times play a central role in contemporary cosmology, most importantly the theory of inflation and dark energy driven expansion late universe. In this work, we give complete list de Sitter solutions semiclassical Einstein equation (SCE), where classical gravity is coupled to expected value renormalized stress–energy tensor free quantum field Bunch–Davies st...

* This investigation was supported in part by the U. S. Atomic Energy Commission. t Although the active concentration of M(OH)2 in the solid phase is generally assumed to be constant, as the entire mass per unit volume does not participate in a reaction, this treatment has admitted the M(OH)2 as a variable in the equation. 1 Adler, E., v.
