Hmm, interesting. But the guy in the video doesn't speak a lot about the criticism of this theorem:

https://en.wikipedia.org/wiki/33_Polyhymnia

For example, the 68 km (42 mi)-diameter asteroid 675 Ludmilla was originally measured to have a density of 73.99±15.05 g/cm3 in Carry's study,[5] but improved orbit calculations in 2019 showed that it had a much lower density of 3.99±1.94 g/cm3.[14]

So there is another meteor, which was estimated the same way at the same time as 33 Polyhymnia, and they measured again later and they found it was 20 times less dense...

While it sounds like an interesting theorem this doesn't shine a good light on it. It's also strange that he "forgot" to mention this in the video.

He does say that the measurements need to be confirmed, but it's way at the end of the video.

Yes, I watched the video, but he didn't mentioned that there was already a similar meteor where they already remeasured. It lowered a bit my expectations after I looked this up.
