hello,
how is it possible to calculate the only GRAVITATIONNAL time dilation and length contraction factor in the Kerr metric and/or the Kerr-Newman metric, for an object falling but otherwise at rest, since there is frame dragging, and the metric contains dt^2 components but also dt.dphi components?
should the time dilation factor always equal the length contraction factor?
the event horizon is for g_rr -> infinite and not g_tt=0
does that mean that g_rr should be the source of the time dilation/length contractor factor, or g_theta_theta and g_phi_phi are also involved?
please reply, this is extremely important
