New type of black hole discovered?

A supermassive black hole found lurking at the edge of the universe is one of the biggest ever detected, according to scientists. The galaxy, nicknamed COS-87259, shines bright from the intense burst of star formation.

The cosmic colossus lies at the centre of an extreme galaxy and is said to date back more than 13 billion years which is only 750 million years after the Big Bang.

The black hole reportedly contains over a billion solar masses worth of interstellar dust - forming stars 1,000 times faster than our own Milky Way.

Additionally, the black hole has an active galactic nucleus which is generating a strong jet of material moving close to the speed of light.

Dr Endsley also said: "While nobody expected to find this kind of object in the very early Universe, its discovery takes a step towards building a much better understanding of how billion solar mass black holes were able to form so early on in the lifetime of the Universe, as well how the most massive galaxies first evolved."
Another article, https://phys.org/news/2023-02-discovery ... holes.html , notes …
What is particularly astonishing about this new object is that it was identified over a relatively small patch of the sky typically used to detect similar objects—less than 10 times the size of the full moon—suggesting there could be thousands of similar sources in the very early universe. This was completely unexpected from previous data.

The only other class of supermassive black holes we knew about in the very early universe are quasars, which are active black holes that are relatively unobscured by cosmic dust. These quasars are extremely rare at distances similar to COS-87259, with only a few tens located over the full sky. The surprising discovery of COS-87259 and its black hole raises several questions about the abundance of very early supermassive black holes, as well as the types of galaxies in which they typically form.
Well it sure is important that we know about this!

Now we have what we need to fix all the problems our tiny world now faces.

Or at least distract voters from what’s happening.

So they say they are able to see 13 billion years into the past. What's stopping them to look just 0.7 billion years further, and confirm their big bang theory?

But I am sure that when they will look 14 billion years into the past and see more galaxies, they will just push back the big bang date, and repeat every time they see further. Clearly this is how you do science, you look at the evidence, and obtain the conclusion, the magic still happens, just the date is incorrect, because the date was obtained by clear evidence. About the magic bang - that is an axiom. It did happen, we just need to fix the date.

As I asked in another thread, some time ago, if "big magic bang" is in fact a natural phenomenon, why can't it happen again? In a bottle of milk maybe, somewhere on Earth? At the time I got answers like "it can't because big bang happened at a time when there was no time or space". So, now because we have "space", this "natural phenomena" just does not happen anymore...
