试验粒子的随机运动意味着G随时间变化

Stochastic motion of test particle implies that G varies with time

D. Momeni

摘要:

这封信的目的是提出一个新的描述时变的引力常量的问题,自然地实现狄拉克的大数假设,在一个新的全息方案的起源引力作为熵力。本文研究了在Verlinde引力\cite{Verlinde}方案中试验粒子随机运动的影响。首先,我们证明了我们必须得到$t\rightarrow\infty$的均分值,这导致了通常的牛顿引力常量。其次,测试粒子运动的随机(布朗)本质,修正了牛顿第二定律。直接结果是牛顿常数与\cite{Running}类似地随时间变化。

英文摘要:

The aim of this letter is to propose a new description to the time varying gravitational constant problem, which naturally implements the Dirac's large numbers hypothesis in a new proposed holographic scenario for the origin of gravity as an entropic force. We survey the effect of the Stochastic motion of the test particle in Verlinde's scenario for gravity\cite{Verlinde}. Firstly we show that we must get the equipartition values for $t\rightarrow\infty$ which leads to the usual Newtonian gravitational constant. Secondly,the stochastic (Brownian) essence of the motion of the test particle, modifies the Newton's 2'nd law. The direct result is that the Newtonian constant has been time dependence in resemblance as \cite{Running}.
