摘要

从广义相对论的标准阿诺维特-戴塞尔-米斯纳（ADM）公式出发，我们从一个具有恒定适当加速度的观察者的角度，构建了一个量子引力的暂定模型，这个观察者就在时空地平线之外。除了得出黑洞热力学的标准结果之外，我们的模型还做出了一个全新的预测：大质量粒子的能量存在一定的上限。例如，对于质子来说，这个上限大约是（1.1乘以10^{21}\）eV。这个结果很有趣，因为这个能量与宇宙射线中测得的质子最高能量的数量级大致相同。

A possible quantum effect of gravitation

Beginning from the standard Arnowitt–Deser–Misner (ADM) formulation of general relativity we construct a tentative model of quantum gravity from the point of view of an observer with constant proper acceleration, just outside of a horizon of spacetime. In addition of producing the standard results of black-hole thermodynamics, our model makes an entirely new prediction that there is a certain upper bound for the energies of massive particles. For protons, for instance, this upper bound is around \(1.1\times 10^{21}\) eV. The result is interesting, because this energy is roughly of the same order of magnitude as are the highest energies ever measured for protons in cosmic rays.

期刊介绍： General Relativity and Gravitation is a journal devoted to all aspects of modern gravitational science, and published under the auspices of the International Society on General Relativity and Gravitation. It welcomes in particular original articles on the following topics of current research: Analytical general relativity, including its interface with geometrical analysis Numerical relativity Theoretical and observational cosmology Relativistic astrophysics Gravitational waves: data analysis, astrophysical sources and detector science Extensions of general relativity Supergravity Gravitational aspects of string theory and its extensions Quantum gravity: canonical approaches, in particular loop quantum gravity, and path integral approaches, in particular spin foams, Regge calculus and dynamical triangulations Quantum field theory in curved spacetime Non-commutative geometry and gravitation Experimental gravity, in particular tests of general relativity The journal publishes articles on all theoretical and experimental aspects of modern general relativity and gravitation, as well as book reviews and historical articles of special interest.
