Superradiant amplification by stars and black holes
... The theory of stellar evolution states that stars whose masses are of the order of the sun’s mass will collapse and reach a final equilibrium state as a white dwarf or a neutron star. However, for much larger masses, these final states can’t be reached and the collapse will continue to such a point ...

The charge begins to leak from both the spheres at a constant rate. As a result the charges approach each other with a velocity ...
