hi,

does anyone know how much exactly time is dilated and space contracted
in rotating black holes, by using the Kerr or Kerr-Newman metrics?

please reply

At the surface black holes violate laws of motion.

Integrate the Kerr/Kerr-Newman line element s = int ( sqrt[ g_uv dx^u dx^v ]
d\tau^2 ) along a path, and you have the answer.
