As a follow up here, I note these reports on the most distant star.
Hubble spots most distant single star ever seen, at a record distance of 28 billion lightyears,

"The star may be up to 500 times more massive than the Sun. The discovery has been published today in the journal Nature."
"When the light that we see from Earendel was emitted, the Universe was less than a billion years old; only 6% of its current age. At that time it was 4 billion lightyears away from the proto-Milky Way, but during the almost 13 billion years it took the light to reach us, the Universe has expanded so that it is now a staggering 28 billion lightyears away."
The paper cited is, A highly magnified star at redshift 6.2,
https://www.nature.com/articles/s41586-022-04449-y
The lensing galaxy redshift is 0.566 while the star is 6.2 redshift reported. The report by phys.org uses the correct comoving radial distance said to be 28 billion light years away but fails to document something important. We cannot see that distance from Earth and that distance uses 4D space expanding faster than c velocity. How does the BB model test the validity of the comoving radial distances used based upon 4D space expanding faster than c velocity? If I was teaching astronomy and cosmology to students, this would be clearly shown to them about the Big Bang model.
