【摘要】：许多关于黑洞疑难的讨论,例如奇点和信息丢失问题,似乎暗示着量子物理和经典引力理论间必须有某种本质的不可调和的冲突,这种冲突无法通过任何半经典的量子化引力模型解决,唯一可能的解决方案只能是某种完整统一的引力量子理论。在本文中,同样是通过半经典分析,显示了只要黑洞蒸发能够满足一个相当宽松的条件:蒸发寿命对外部观察者有限,那么无论蒸发机制的细节和过程如何,上述黑洞疑难都可以自然地避免。而这个条件显然可以被Hawking-Unruh机制所满足。因此,量子物理和经典引力理论间的冲突有可能未必像看上去那么严重,半经典方法的有效性可能被低估了。本文中还给出了爱因斯坦引力场方程球对称的最一般精确解,任何具有球对称的Einstein场方程解都是其特例,包括Schwarzschild外部解和内部解、R-N解、静态理想流体球解,以及一切可能的具有球对称性的动态解。另外,本文还对[Haw75]中首次给出的关于蒸发黑洞的Penrose图的一些问题给出了澄清。
[Abstract]:A lot of difficult discussions such as black hole singularities and the information loss problem, seems to imply that there is some essential quantum physics and classical theory of gravitation between the irreconcilable conflict, the conflict cannot be solved by any semi classical quantized gravity model, the only possible solution is only a complete and unified quantum theory of gravity.
In this paper, the same is through the semi classical analysis shows that, as long as the black hole evaporation can meet a very relaxed condition: the evaporation life of an external observer, then no matter how the evaporation mechanism of the details and process, the black hole difficulties can be naturally avoided. And this condition can apparently be satisfied. Therefore the mechanism of Hawking-Unruh conflict, quantum physics and classical theory of gravitation between might not be as bad as it seems, the validity of semiclassical method may be underestimated.
This paper also gives the Einstein gravitational field equation of spherical symmetry the exact solution, any Einstein field equation with spherical symmetric solution is a special case, including external and internal solutions of Schwarzschild solution, R-N solution, static perfect fluid sphere solution, and all possible with spherical symmetry of the dynamic solution.
In addition, this paper also on the Penrose graph of evaporating black hole are given for the first time in [Haw75] some of the problems are given to clarify.
