论文摘要
如果有人考虑两个颗粒的前碰撞，那么施瓦茨柴尔德时空的质量能量可以任意高，其中一个沿所谓的白洞大地测量学移动，而另一个沿着黑洞地球孔移动。如果人们认为重力崩溃模型，则可以进行此过程。在本文中，我们考虑了Vaidya时空中众所周知的赤裸裸的奇异性形成，并研究了有关倒塌云边界附近的两个粒子碰撞的问题。考虑了前碰撞的质量能量。一个粒子从裸露的奇点移开，另一个粒子落在塌陷的云上。我们表明，如果碰撞发生在保形杀戮地平线附近，则质量中心能量会不可依赖。
The center-of-mass energy can be arbitrarily high in Schwarzschild spacetime if one considers the front collision of two particles, one of which moves along so-called white hole geodesics and another one along a black hole geodesic. This process can take place if one considers the gravitational collapse model. In this paper, we consider the well-known naked singularity formation in Vaidya spacetime and investigate the question about two particle collision near the boundary of the collapsing cloud. The center-of-mass energy of the front collision is considered. One particle moves away from the naked singularity and another one falls onto a collapsing cloud. We show that the center-of-mass energy grows unboundly if the collision takes place in the vicinity of the conformal Killing horizon.
