James Webb Space Telescope reveals that most galaxies rotate clockwise

> The same solo author (a computer scientist) has made many similar claims based on a variety of datasets. Often coming to completely contradictory conclusions. Some of these claims have been followed up by astronomers, who found errors in his analysis and poor statistical tests. His claims have been discussed in this sub before. Independent studied have found no significant evidence of anisotropy.

>Take his claims about JWST as an example. In 2024 he wrote a paper about some early data, claiming to find more galaxies rotating with the Milky Way. He claimed based on a sample of just 34 galaxies that the signal was significant. Now he has looked at a wider dataset of the same area, which should allow him to verify his analysis. But it shows exactly the opposite, more anti. So he writes a paper saying this new result is definitely significant but doesn't reflect on the fact he has written two papers which contradict each other. He has failed to reproduce his own result. The take away is that his results are not as significant as he claims. He's also looking at a tiny area, and nearby galaxies can have correlated spins. He doesn't take this into account either. There are multiple JWST fields in different directions he could examine in different directions to test his claims, there are two JADES fields, but he only publishes one.

>I do wish the MNRAS editors would take measures to stop publishing low quality claims like this without more robust review. If you look at the text, it’s largely repeating results from his old papers. There’s very little discussion of the new results.
