How to Calculate the Redshift of an Event Horizon

As you get closer to the singularity, things will start to Redshift again and eventually Redshift asymptotically down to a frequency of zero or an infinite wavelength. That may be true. I don't remember actually. This is a trick your calculation to do because the easy calculation to do is to pretend that there's somebody who can measure the energy and that somebody is not moving with respect to the nicest coordinate system that you have. But once you get inside the event horizon and for rotating black holes, it's even farther out, there is no observer who can sit there in your nice coordinate system without moving. All observers are forced to move. It doesn't matter how
