But the rate of orbital decay of pulsars in binary systems is very precisely matched by general relativity, which is going to be very hard to explain with a different cause. Given that GR has been verified so thoroughly, while on the other hand models of the gravitational background depend on so many assumptions and simulations and approximately measured empirical relationships about supermassive black hole (SMBH) sizes, occurrences, time for SMBH mergers, etc, as detailed in the article, clearly this is incredibly weak evidence that gravitational waves don't exist. But something is wrong somewhere.
