Eicheons而不是黑洞

Eicheons instead of Black holes

Sergey L. Cherkas, Vladimir L. Kalashnikov

摘要:

在共形么模度规下,得到了引力场的一个新的球对称解。通过将坐标变换为保角幺模度规,证明了标准Schwarzschild度规中的黑洞视界表面可以压缩为一点.在这个新的度规中,没有黑洞视界,而裸奇点对应于一个点质量粒子。研究这种特殊量规的原因(即,共形么模度量)与真空能量问题的关系。这旨在将它与其他物理现象(包括黑洞)联系起来,人们可能会认为它们应该在这个特定的度量中考虑。这意味着广义相对论的规范不变性的破坏。因此,非奇异的“eicheons”表现为具有不同质量和结构的非点紧天体。它们是恒星坍缩的最终产物,质量超过了托尔曼-奥本海默极限。

英文摘要:

A new spherically-symmetric solution for a gravitational field is found in the conformally-unimodular metric. It is shown, that the surface of the black hole horizon in the standard Schwarzschild metric can be squeezed to a point by converting coordinates to the conformally-unimodular metric. In this new metric, there is no black hole horizon, while the naked singularity corresponds to a point massive particle. The reason for the study of this particular gauge (i.e., conformally-unimodular metric) is its relation to the vacuum energy problem. That aims to relate it to other physical phenomena (including black holes), and one could argue that they should be considered in this particular metric. That means the violation of the gauge invariance of the general theory of relativity. As a result, the nonsingular "eicheons" appear as the non-point compact objects with different masses and structures. They are a final product of the stellar collapse, with the masses exceeding the Tolman-Oppenheimer-Volkoff limit.
