Equivalence of Descriptions of Gravity in Both Curved and Flat Space-time
نویسنده
چکیده
It is proved in the manuscript that as long as the proper coordinate transformation is introduced , the equations of geodetic lines described in curved space-time can be transformed into the dynamic equations in flat space-time. That is to say, the Einstain theory of gravity and other gravitational theories based on the curved space-time can be identically transformed into flat space-time to describe. As an example, the Schwarzschild solution of the spherical symmetry gravitational field is transformed into flat space-time to study. The results show that there exists no any singularity in the all processes and the whole space-time including at the point r=0. So it seems more rational to discuss the problems of gravitation in flat space-time. PACS number 0400

Simultaneous emergence of curved spacetime and quantum mechanics
It is shown in this paper that the geometrically structure-less spacetime manifold is converted instantaneously to a curved one, the Riemannian or may be a Finslerian spacetime with an associated Riemannian spacetime, on the appearance of quantum Weyl spinors dependent only on time in that background flat manifold and having the symplectic property in the abstract space of spinors. The scenario...
متن کاملSpacetime Geometry with Geometric Calculus
Geometric Calculus is developed for curved-space treatments of General Relativity and comparison with the flat-space gauge theory approach by Lasenby, Doran and Gull. Einstein’s Principle of Equivalence is generalized to a gauge principle that provides the foundation for a new formulation of General Relativity as a Gauge Theory of Gravity on a curved spacetime manifold. Geometric Calculus provi...
متن کاملIntroduction to Tensor Calculus for General Relativity
There are three essential ideas underlying general relativity (GR). The first is that spacetime may be described as a curved, four-dimensional mathematical structure called a pseudo-Riemannian manifold. In brief, time and space together comprise a curved fourdimensional non-Euclidean geometry. Consequently, the practitioner of GR must be familiar with the fundamental geometrical properties of c...

Received (Day Month Year) Revised (Day Month Year) Recent developments in simulating fundamental quantum field theoretical effects in the kinematical context of analogue gravity are reviewed. Specifically, it is argued that a curved space-time generalization of the Unruh-Davies effect – the Gibbons-Hawking effect in the de Sitter space-time of inflationary cosmological models – can be implement...
متن کاملDesperately Seeking Curved-spacetime — Turn to Experimental Resolution?
Gravity whose nature is fundamental to the understanding of solar system, galaxies and the structure and evolution of the Universe, is theorized by the assumption of curved spacetime, according to Einstein , s general theory of relativity (EGR). Particles which experience gravity only, move on curved spacetime along straight lines (geodesics). The geodesics are determined by curved-spacetime me...
