- TL;DR Summary
- More "hair" (fractal surface) ascribed to black holes. How serious is the professional community looking at this?
This should maybe go in the Beyond The Standard Model forum but since it's a paper about quantum cosmology I'll put it here. Feel free to move it if it's too speculative but that's exactly my question. That is: if it is...

It would seem that yet more "hair" is now being ascribed to black holes. This time fractal surface. It wouldn't really surprise me if black holes surfaces are indeed fractal. After all, most, if not all, natural objects are. Examples are legion. In the paper they mention the skin of an elephant but the list goes on an on. Just consider pepples, beaches, mountains, plants, etc. If this picture is correct it must have implications for Hawking radiation, which is in fact mentioned, I think. More virtual particles should logically escape if the surface is bigger.
This picture makes sense to me. At least intuitively, which I know is a bad way of judging these things. Quantum Mechanics being a case in point! But then again, happy amatoer and all. At least my (perhaps rather naive questions) are at least founded in actual papers.)
How seriously is this idea taken by the professional physics community? There are more papers deling with this, although they may not be pertainig to black holes specifically. As I'm just an interested amatoer I may not be able to judge their relevance.
