Some of the findings match a pre-existing pipe dream but this boring alternative is pretty neat too:

The latest findings do not provide definitive proof of black hole cosmology, with more evidence required to fully understand the implications.

Shamir noted that an alternative explanation for why most of the galaxies in the study rotate clockwise is that the Milky Way’s rotational velocity is having an impact on the measurements.

“If that is indeed the case, we will need to re-calibrate our distance measurements for the deep universe,” said Shamir.

"The re-calibration of distance measurements can also explain several other unsolved questions in cosmology such as the differences in the expansion rates of the universe and the large galaxies that according to the existing distance measurements are expected to be older than the universe itself.”

The research was published in Monthly Notices of the Royal Astronomical Society, in a study titled ‘The distribution of galaxy rotation in JWST Advanced Deep Extragalactic Survey’.

It is an observation consistent with black hope cosmology, but other explanations are possible too, so nobody is claiming it's proof
