Gravitational Curvature: An Introduction to Einstein's Theory Theodore Frankel
Publisher: Dover Publications

Various attempts have been made so far at solving the problem The results compare favourably with theory and provide an accessible but detailed introduction to quantum gravity via a simulation that runs on a computer. Einsteinian physics is the culmination of centuries of debate. Jun 6, 2008 - Article Title: Introduction to modified gravity and gravitational alternative for dark energy. General relativity takes the form of field equations But the entire system is based upon the synchronization of these satellites that had to be programmed with corrections to take into account the curvature of space-time near Earth. Mar 25, 2014 - This is why you don't have to worry about post-post Newtonian corrections if you ask Siri for directions, but also why it takes some experimental effort to detect the subtle consequences of Einstein's theory of General Relativity – and that's the classical case. This modification was put forward in 1922 by Elie Cartan, First, it is written in a colloquial style and is intended to be a pedagogical introduction to the gauge approach to gravity. But for now, we are simply taking the trouble to find appropriate and fun ways to introduce students to the real world of physics. In the ƒ(R) gravity, the Einstein-Hilbert action, which is linear in the scalar curvature R, is replaced with a proper function of R. Jan 16, 2014 - The problem of unifying Einstein's theory of General Relativity with Quantum Field Theory is an unsolved problem at the heart of understanding how gravity works at the fundamental level. Although it has not yet been confirmed if these modified gravity theories do actually describe dark energy, we have discovered that these concepts could potentially be promising ones. Abstract: The Einstein--Cartan Theory (ECT) of gravity is a modification of General Relativity Theory (GRT), allowing space-time to have torsion, in addition to curvature, and relating torsion to the density of intrinsic angular momentum. Authors: Nojiri, S;Odintsov, SD of the Einstein gravity. Apr 18, 2010 - General relativity was Einstein's theory of gravity, published in 1915, which extended special relativity to take into account non-inertial frames of reference — areas that are accelerating with respect to each other. Could there be strong curvature regions in our universe that are not hidden behind event horizons and allow us to look straight onto large quantum gravitational effects? Nov 8, 2012 - Our modern understanding of the universe is based on two theories of physics developed by Einstein – the theory of gravity, called General Relativity and the theory of particle interactions called Quantum Mechanics.
