In a Kerr Black Hole there exists a region called the Ergosphere.
It is between the Event Horizon and a spheriod called the Static Limit.
The Event Horizon can be simplified to: ##\Delta## = 0.
The Static Limit can be simplified to: ##g_{tt}## = 0.
They yield two separate spheres the Static Limit being greater.
Is it theoretically possible to extract energy and mass from the black hole in this region?
Particles within this ergosphere must co-rotate with the inner mass if they are to retain their time-like character.
