评论“加速粒子通过引力排斥在史瓦西领域的高能量”[Astropart。物理86(2017)18-20]

Comment on "Acceleration of particles to high energy via gravitational repulsion in the Schwarzschild field" [Astropart. Phys. 86 (2017) 18-20]

Alessandro D. A. M. Spallicci

摘要:

McGruder III(2017)最近发表的一篇论文中,作者在Schwarzschild-Droste解决方案的背景下处理了引力排斥的概念。进入黑洞的粒子的斥力(减速)是一个概念,从1916年德罗斯特开始,这个概念被多次提出。它是一种坐标效应,当使用坐标时间时,在距离黑洞很远的地方,观察者会看到这种效应。排斥与黑洞的局部物理学没有关系,而且它也不能对加速出射的粒子负责。因此,宇宙射线的能量提升不能通过排斥产生。

英文摘要:

Comments are due on a recent paper by McGruder III (2017) in which the author deals with the concept of gravitational repulsion in the context of the Schwarzschild-Droste solution. Repulsion (deceleration) for ingoing particles into a black hole is a concept proposed several times starting from Droste himself in 1916. It is a coordinate effect appearing to an observer at a remote distance from the black hole and when coordinate time is employed. Repulsion has no bearing and relation to the local physics of the black hole, and moreover it cannot be held responsible for accelerating outgoing particles. Thereby, the energy boost of cosmic rays cannot be produced by repulsion.
