Semi-Teleparallel Theories of Gravitation
A class of theories of gravitation that naturally incorporates preferred frames of reference is presented. The underlying space-time geometry consists of a partial parallelization of space-time and has properties of Riemann-Cartan as well as teleparallel geometry. Within this geometry, the kinematic quantities of preferred frames are associated with torsion fields. Using a variational method, i...
متن کاملMie’s Theories of Matter and Gravitation
Unifying physics by describing a variety of interactions – or even all interactions – within a common framework has long been an alluring goal for physicists. One of the most ambitious attempts at unification was made in the 1910s by Gustav Mie. Mie aimed to derive electromagnetism, gravitation, and aspects of the emerging quantum theory from a single variational principle and a well-chosen Lag...
متن کاملOn the History of Fourth Order Metric Theories of Gravitation
We present the history of fourth order metric theories of gravitation from its beginning in 1918 until 1988.
متن کاملTheory of gravitation theories: a no-progress report
Already in the 1970s there where attempts to present a set of ground rules, sometimes referred to as a theory of gravitation theories, which theories of gravity should satisfy in order to be considered viable in principle and, therefore, interesting enough to deserve further investigation. From this perspective, an alternative title of the present paper could be “why are we still unable to writ...
متن کاملMasses of Stellar Black Holes and Testing Theories of Gravitation
The paper analyzes the mass distribution of stellar black holes derived from the light and radialvelocity curves of optical stars in close binary systems using dynamical methods. The systematic errors inherent in this approach are discussed. These are associated primarily with uncertainties in models for the contribution from gaseous structures to the optical brightness of the systems under con...
