Feynman's argument is made from a phenomenon predicted for rotating black holes, that is analogous to stimulated emission. I believe Hawking radiation is predicted for all black holes, whether rotating or not, so I am wondering if there is a phenomenon analogous to stimulated emission from non-rotating black holes? (I am making an analogy of analogies here: if the original phenomenon is like stimulated emission from rotating black holes, and Hawking radiation is the corresponding spontaneous emission, then is Hawking radiation from stationary black holes also like spontaneous emission, and if so, what is the corresponding stimulated emission?)
