Query: On the third law of black hole dynamics   The third law of black hole dynamics states that the surface gravity
(temperature) of black hole cannot be reduced to zero in finite sequence of
physical interactions. We argue that the same is true when surface gravity is
replaced by gravitational charge. We demonstrate that the prescribed window for
infalling energy and radiation pinches off as extremality ($M^2 = a^2 + Q^2 $)
is approached.
