- convert a differential version to absolute version of time dilation formula
Just as the time dilation formula for the Schwarzschild metric in terms of the position away from center of mass for a gravitational body and the Schwarzschild radius is given by
so I'd like to know the corresponding absolute (non-differential) form for the Kerr metric but all I could find for the Kerr metric time dilation formula was some differential ratio subtracted from unity. In terms of the modified distance which reduces to if the Kerr time dilation is apparently given by (if this can be trusted)
How can I a) get rid of the subtraction from unity, and b) not have it in the differential form but rather just the absolute form like above for the Schwarzschild metric: , time on a moving frame relative to a reference frame on which is the reference time ?
If anyone has derived these other absolute time dilation formulae for the Kerr-Newman and Reissner-Nordstrom cases as well please do share.
