This spinning area surrounding the event horizon is called the ergosphere and has an ellipsoidal shape.
这活动视界周围旋转的区域是所谓的能层而具有椭圆形。
The ergosphere becomes thicker and the Hawking temperature changes when the mass of the black hole decreases.
当黑洞质量减小时，外能层变厚，辐射温度也发生变化。
However, because space-time itself is moving in the ergosphere, it is impossible for objects to remain in a fixed position.
然而因为时空本身是在能层里移动，物体保持在固定位置是不可能的。
