Hello,
i have some problems with the ergosphere of a rotating black hole.
I can show that an object must rotate with the black hole and a can determine the intervall of possible velocitys. But is it possible to calculate the exact velocity? How it depends on the initial velocity of the object?
If the object has an velocity which matches to the intervall in the ergosphere, would it be constant or will it also be affected by the ergosphere?
What about the conservation of angular momentum (for example if it rotates in the other direction), would it be taken from the black hole (or given to the black hole)?
If we are intressted in a stable oribit in the ergosphere, how will this depend on the frame-dragging effect?
Thanks for your help
