One trivial point -- if you're in free fall I don't think there is any Rindler boundary. You're following a geodesic, and not "really" accelerating.

You can't just apply SR in the curved spacetime around a gravitating mass and get the right answer. In fact, while you certainly /can/ apply SR in an accelerated frame (with some care), you can't really apply it at all in non-flat space. The math of SR assumes a fixed metric, which you haven't got in a gravitational field. In general, while I don't _think_ there is, I have no idea how you'd go about determining for sure whether there's an event horizon due to acceleration when free-falling in a gravitational field.

I have read Dr. McCulloch's book and find his theory interesting.

However, my training in RF gives me a different perspective on wave phenomena that doesn't seem to match up with his theory. In his theory, he drops out wavelengths of EM background radiation that would be filtered in the frequency domain due to the Rindler boundary which moves closer to the object depending on acceleration. However, in the time domain these waves would have to propagate the distances to the discontinuity and back before any cancellations could occur. The boundaries in question are huge distances away. For example, for a free fall acceleration on the Earth (9.8m/s^2), the boundary would be changed to 10 light years away. The change in inertial mass induced by an acceleration will not know of the discontinuity until twice the time to the discontinuity. That would mean that the object being accelerated at 9.8m/s^2 should not know of the boundary for at least 20 years. If the object instantaneously experienced a change in inertial mass, it would seem to violate causality by this theory.

I have written to Dr. McCulloch to ask him how I get past this understanding. Do any of you have an opinion on this issue?
