Hi everyone! I was thinking about gravitational waves and gravitons and I realized that I did not fully understand the purpose of quantizing gravitational waves. I understand that quantizing electromagnetic waves gets rid of the classical physics prediction of the Ultraviolet Catastrophe (UVC) (note that I understand it did not get rid of it. It showed why the UVC problem doesn't happen). But what is the UVC analogue to gravitational waves predicted by classical general relativity?
