This vision builds on (i) mathematical results in symmetry-reduced general relativity and (ii) on a paradigm shift in analog gravity. For this, consider the field of analog gravity at first. The ability to repr
What force is explained by general relativity? General relativity explains gravity, and in this theory, it is not really a "force" anymore. The gravitational field comes out of the description of general relativity as a result of the curved spacetime. When was the theory of general relativity ...
According to Eddington, the Archbishop of Canterbury once asked Einstein about the relevance of relativistic physics for religion; Einstein replied that relativity was a purely scientific theory and had no relevance to religion (Eddington1939, p. 7). Those who have suggested that General Relativity p...
http://en.wikipedia.org/wiki/Congruence_(general_relativity) (Btw, the standard definition requires the family of worldlines to be non-intersecting.) A congruence of timelike worldlines is only hypersurface orthogonal if the vorticity vanishes, but the Raychaudhuri equation is completely general and...
since the other postulates of Relativity imply it very strongly. If x and t are so easily transformable, in such a simple equation as x = ct, then the two variables cannot be traveling at complex angles to one another. We simply cannot use hyperbolic math with confidence in physical situati...

However, one can also interpret it as the action of a field theory, for which the geometry of the membrane is the field—much in the same sense in which general relativity is a field theory built on the geometry of space-time. With this viewpoint, Eq. (2) is the free field equation...
Simply, SRT was void of such an “etheric” medium in the derivation of the theory whose mathematically predictive results matched empirical data…or was it really devoid of the “ether”? You see, Einstein used the Principle of Relativity and Constancy of Light in any inertial frame of ...
Imposing a local symmetry under the general linear group singles out the general teleparallel equivalent of General Relativity carrying both torsion and non-metricity. We provide a detailed discussion on the teleparallel equivalents of General Relativity and how the two known equivalents, formulated on ...
Presumably he and other logical empiricists would have been interested in the bear- ing of General Relativity on the philosophy of mind (if there is one) and likely would have been pleased to find therein some evidence against interactionism. 1.1 Enter General Relativity What difference does...
