This region of twisted spacetime is called the ergosphere.
The term ergosphere comes from the Greek word for "work.
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.
From (46) it is concluded that there exists no spacetime drag effect for the rotating point-mass and no ergosphere.
From (50) it is concluded that there exists no spacetime drag effect for the rotating point-charge, and no ergosphere.
