AI中文摘要：
我们考虑在Schwarzschild背景下自由运动的粒子之间的碰撞。我们提出了导致质心系中无界能量输出的场景分类。尽管这在黑洞外部是被禁止的，但在完整的时空图中，考虑到白洞区域和镜像宇宙，这种现象成为可能。此外，我们仔细审查了分叉点附近的碰撞，并揭示了视界内部区域中静止观察者的作用。在某些场景中，$E_{c.m.}$不仅发散，而且看似变为无穷大，但根据所谓的运动学审查原则，这实际上是不可能的。我们解决了相应的悖论，并论证了为什么这一原则仍然有效。
英文摘要：
We consider collisions between particles moving freely in the Schwarzschild background. We suggest classification of scenarios that lead to unbounded energy output in the center of mass frame. Although this is forbidden in the exterior of a black hole, the phenomenon becomes possible with account of white hole region and mirror universe in the complete space-time diagram. Also, we scrutinize collisions in the vicinity of the bifurcation point and reveal the role of resting observers in the inner region beyond the horizon. In some scenarios $E_{c.m.}$ not only diverges but becomes seemingly infinite that is, as a matter of fact, impossible according to the principle of so-called kinematic censorship. We resolve a corresponding paradox and argue, why this principle remains valid.
