扩展的广义相对论:五维真空的大尺度反引力和ω=-1的短尺度引力

Extended General Relativity: large-scale antigravity and short-scale gravity with ω=-1 from five dimensional vacuum

Jose Edgar Madriz Aguilar, Mauricio Bellini

摘要:

考虑一个具有特定的静态Ricci平坦度规的五维黎曼时空,我们在诱导物质理论的框架下得到了一个有效的四维静态球对称度规,它在小尺度(行星和天体物理)上给出了普通的引力解,而在非常大的尺度(宇宙学)上给出了排斥力(反引力)解,其中ω=-1。我们的方法是一个统一的方式来描述暗能量,暗物质和普通物质。我们用两个例子来说明这个理论,太阳系和大吸引子。从几何的角度来看,这些结果遵循的假设,存在一个约束力,使测试粒子在一个给定的4D超曲面上移动。

英文摘要:

Considering a five-dimensional (5D) Riemannian spacetime with a particular stationary Ricci-flat metric, we obtain in the framework of the induced matter theory an effective 4D static and spherically symmetric metric which give us ordinary gravitatory solutions on small (planetary and astrophysical) scales, but repulsive (antigravity) forces on very large (cosmological) scales with ω= -1. Our approach is an unified manner to describe dark energy, dark matter and ordinary matter. We illustrate the theory with two examples, the solar system and the great attractor. From the geometrical point of view, these results follow from the assumption that exists a confining force that make possible that test particles move on a given 4D hypersurface.
