最近有人指出，在克尔黑洞外从无穷远处静止自由下落的粒子，在最大黑洞自旋的极限情况下，原则上可以与任意高的质能中心碰撞。在这里，我们的目标是阐明这一令人着迷的结果的机制，并指出其实际局限性，这意味着超能量碰撞在自然界中不可能发生在黑洞附近。
It has recently been pointed out that particles falling freely from rest at infinity outside a Kerr black hole can in principle collide with an arbitrarily high center of mass energy in the limiting case of maximal black hole spin. Here we aim to elucidate the mechanism for this fascinating result, and to point out its practical limitations, which imply that ultraenergetic collisions cannot occur near black holes in nature.
