Desperate to keep to the mainstream position astrophysicists ae spinning the evidence. One might argue. At https://phys.org/news/2025-05-deepening-mystery-jwst-early-galaxies.html … and the research paper is presently on the arXiv server, it would seem. See https://doi.org/10.48550/arxiv.2505.09669 … The headline at the press release is ‘The deepening mystery around the James Webb Space Telescope’s early galaxies.’ A while ago there were attempts to rubbish the idea these galaxies were really as early as portrayed. It does not seem to have worked if most scientists still accept these galaxies came into being shortly after Big Bang. The new research paper seems to think they are early and they claim that it is not so bad as made out as there is no evidence, as yet, of active black holes in those galaxies.
Shortly after the James Webb Space Telescope was started up it began beaming back images that ran counter to mainstream ideas. This included the discovery that the furthest galaxies away, visible to the telescope, should date back to shortly after Big Bang. Unfortunately for them, the galaxies were full sized and not in the process of coming into being. It was an issue that required an explanation. Hence, the various attempts to explain it away without abandoning the idea of Big Bang. The Big Bang paradigm is so heavily entrenched it will take a telescope with a range much bigger than James Webb to bring it down. If a new telescope was able to peer even further back into the past – assuming the universe is actually growing in the way envisaged, but that is years away from fruition. Eye watering sums of money have already been spent on the current crop of telescopes – coming on stream in the last few years.
Getting back to the quiescent black holes. Apparently, they are not emitting X-rays. This, it is presumably thought, may indicate they are young galaxies. We shall have to wait and see. Early days.
