Einstein's theory of gravity is also a structure \\((\\mathcal {M},g)\\) , but space-time geometry in the presence of gravitational fields is not longer flat, the curvature tensor describing the tidal actions. For vanishing gravitational fields the structure \\((\\mathcal {M},g)\\)...
which unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime. Modern physics is built on two pillars: one is quantum theory, which controls the smallest particles in the universe; Another
Beyond Einstein's theory of gravitation : some aspects of loop quantum cosmology, black holes and the dark universe In this thesis we explore the phenomenology of some extensions to General Relativity and quantum gravity theories.The motivation for this research lies in the incompleteness of the ...
The analogy between electrodynamics and the translational gauge theory of gravity is employed in this paper to develop an ansatz for a nonlocal generalizat... FW Hehl,B Mashhoon - 《Physical Review D》 被引量: 102发表: 2009年 The energy problem in Einstein's theory of gravitation (Dedicated...
Testing Einstein's theory ofgravity by lunar laser rangingJürgen Müller, Manfred Schneider,Michael Soffel, Hanns RuderAbstract. The Moon—the only natural satellite of the Earth—can be used to testEinstein's theory of gravity in the first post-Newtonian approximation. The prerequi-sites have bee...
How does the electromagnetic field couple to gravity, in particular to metric, nonmetricity, torsion, and curvature? (ii) One desires to test out alternatives to Einstein's gravitational theory, in particular those of a gauge-theoretical nature, like Einstein-Cartan ... FW Hehl,YN Obukhov - ...
Universality of Gravity from Entanglement Inparticular, the CFT first law leads to Newton's Law of gravitation and the factthat all sources of stress-energy source the gravitational field. In ... B Swingle,M Van Raamsdonk - 《Eprint Arxiv》 被引量: 213发表: 2014年 加载更多来源...

what came to be called his "Special Theory of Relativity." Ten years later he expanded it to a "General Theory of Relativity." Albert Einstein's theories of relativity are about the basic ideas we use to describe natural happenings. They are about time, space, mass, movement, and gravity...
Einstein's Theory of General Relativity- the more comprehensive theory, which treats gravity as a geometric phenomenon of a curved spacetime coordinate system, which also includes noninertial (i.e. accelerating) frames of reference Fundamental Principles of Relativity ...
