What did they say, again, about moderation on arXiv being too strict? |

Two weeks ago Anton Petrov posted a video claiming that JWST galaxies were explained by the Renaissance simulation of the early universe. The work published on ArXiV uses a statistically rare occurrence of developed galaxies in the simulation to claim that it explains JWST observations.
Indeed it explains observations with the corresponding statistically low degree of confidence - in other words it doesn't explain anything but a fluke in the simulation.
This other video published a week ago, Evidence That Some JWST Galaxies May Instead Be Something Exotic, proposes another explanation for the galaxies observed by JWST (needed because the Renaissance explanation is worthless...)
The explanation (one of many others that don't work) is based on the hypothesis of dark stars, a dense accumulation of dark matter with some hydrogen and helium gas orbiting around the dark star.
To make this hypothesis work one needs to assume:
The large number of assumptions to make this work is a sign of very bad science. The article, as described by Anton Petrov, is not credible at all.
P.S. JADES-GS-z13-0 and other galaxies look small because at redshift z = 13.2 their distance is 35 Gly.
This is a followup to the post by Mitchell on May 29th
