大质量引力对反引力和/或暗物质的贡献

Anti-gravity and/or dark matter contributions from massive gravity

Michael V. Bebronne

摘要:

近年来,在描述洛伦兹不变性自发破缺的大质量引力子的理论中,发现了引力场方程的静态球对称解。这些解决方案,其中显示两个积分常数,而不是一个在广义相对论,进行了讨论。它们是修正的黑洞的候选者,只要它们对小扰动是稳定的。这些解决方案可能有吸引力或排斥行为在大的距离。因此,这些经过改造的黑洞可能会模仿暗物质的存在,或者是反重力的来源。

英文摘要:

Recently, the static spherically symmetric solution of the gravitational field equations have been found in theories describing massive graviton with spontaneous breaking of the Lorentz invariance. These solutions, which show off two integration constants instead of one in General Relativity, are discussed. They are candidates for modified black holes provided they are stable against small perturbations. These solutions may have both attractive or repulsive behavior at large distances. Therefore, these modified black holes may mimics the presence of dark matter or be a source of anti-gravity.
