On the opacity of the event horizon to changing magnetic fields

by John Reid

Electromagnetic waves cannot escape from a black hole. Hence information about changed electromagnetic conditions inside a black hole carried by an electromagnetic wavefront cannot escape either. Electrostatic fields are unaffected by the event horizon, so it must be changes in the magnetic component of the electromagnetic wave which cannot penetrate it; the event horizon must be opaque to magnetic field changes. Gravitational waves are described by the same equations and have the same velocity as electromagnetic waves. They too cannot escape a black hole and the event horizon must also be opaque to gravitomagnetic field changes. This opacity leads to the generation of short-lived, electromagnetic and gravitoelectromagnetic shocks whenever a massive object is absorbed by a black hole. Two implications of this proposition are discussed: the excitation of plasmas in relativistic jets and the redistribution of angular momentum within galaxies.

Dear Dr. Reid:

I am writing to you with regard to your manuscript cited above, which you recently submitted to The Astrophysical Journal. I regret to tell you that we are not able to undertake further consideration of your submission for publication in the AAS Journals.

There is a substantial literature on the behavior of perturbations, including electromagnetic fields, near black holes. This manuscript is substantially below the state of the art in the field.

Author’s comment:
Fair enough. I guess it does look amateurish to an expert in the field. Nevertheless, I believe the idea of the generation of EM and GEM shocks by event horizon opacity to be new. I would like to see someone familiar with tensor calculus and General Relativity develop it in a more publishable form.
