Sorry, I think I came off as too confident in my previous comment. I’m quite sure about my first paragraph but the rest is just speculation from an amateur.
If I would risk speculating even further though, there’s some similarity between the infinite energy found in the ultraviolet catastrophe, and the infinite density we now hypothesize for black holes. It seems unreasonable that it would actually be infinite, and it’s possible that quantization of gravity plays a part in preventing that from happening.
