In this process, all of the action takes place outside the black hole's event horizon, the boundary beyond which nothing can escape, in a flattened region called the ergosphere.
The faster the black hole spins, the larger its ergosphere becomes, which allows high-energy collisions further from the event horizon.
In addition, only a small portion of high-energy gamma rays managed to escape the ergosphere.
b] is an ergosphere, in which spacetime is dragged in the direction of the of rotation of the point-charge.
The so-called ergosphere also arises from the aforesaid misconceptions.
There is no rotational drag on spacetime, no ergosphere and no event horizon, i.
