Dear Christian Corda,
Very happy to see you again. I have downloaded a number of your papers, including your 2018 GRF essay, and find your proposal of quasi-normal modes fascinating. Several years ago I derived the key results of Verlinde's holo-model by discarding the idea of 'information' and deriving Bekenstein's "area quantization" based purely on energy. The addition of photons distributed over the black hole change as the hole grows, and the computation is simplified by adding photons in the right order. Nevertheless, they could conceivably come in any order, and this would be expected.
After reading your work on quasi-normal modes, I think this approach is compatible with your theory, and realize that emission as well as absorption occurs, and particularly, as you say:
"The emission of a particle...causes a decrease in the horizon..."
and, more specifically, that:
"The correspondence between emitted radiation and proper oscillation of the emitting body is a fundamental behavior of every radiation process in Science."
I have not tied my results to your equations, but if I manage to obtain anything that I think you might be interested in, I will surely contact you.
Meanwhile, I invite you to read my essay, Deciding on the nature of time and space, and welcome your comments.
Warmest regards,
Edwin Eugene Klingman
