Ultraviolet catastrophe is cool! It’s why we needed quantum physics, otherwise there would be catastrophic infinite energy emerging from random high frequency oscillations!
Well that's not quite what it is, first of all, and second of all I don't like the practice of calling something a catastrophe when its just predicted by a theory, but didn't happen. I mean, bad theories always predict something horrible should be happening. What's next, do flat earthers get to have an "ocean water catastrophe" because their theory implies all the water drains away? Or a "super luminal" catastrophe because their theory requires infinite unending linear acceleration of the earth (and moon and sun)? I mean, it really is a catastrophe I guess...for the theorist.
