随机量子引力、引力坍缩与灰洞

Stochastic Quantum Gravity, Gravitational Collapse and Grey Holes

J. W. Moffat

摘要:

量子引力被视为广义相对论时空度规的随机量子化。结果表明,由于几何的随机涨落行为,恒星引力坍缩中奇异性的发生概率密度为零。此外,当恒星坍缩时,一个遥远的观测者在恒星史瓦西半径处看到无穷大的红移的概率密度为零。因此,在引力坍缩过程中,黑洞事件视界的形成概率密度为零。一个灰色的明显的事件视界在坍缩过程中形成,允许信息逃逸。

英文摘要:

Quantum gravity is treated as a stochastic quantization of the spacetime metric of general relativity. It is found that owing to the stochastic fluctuating behavior of the geometry, the singularity in gravitational collapse of a star has a zero probability density of occurring. Moreover, as a star collapses the probability density of a distant observer seeing an infinite red shift at the Schwarzschild radius of the star is zero. Therefore, there is a vanishing probability density of a black hole event horizon forming during gravitational collapse. A grey apparent event horizon forms during the collapse that allows information to escape.
