They produced conceptual breakthroughs that have advanced our understanding of black hole physics in ways not previously possible. If that was just lying around as a simple repurposing of a Fourier analysis, it wouldn't have sat around as an unresolved problem for decades. But I understand that words meaning things is not part of the operative definition of success in the goalpost relocation industry.
