Oxygen discovered in most distant galaxy ever seen: 'It is like finding an adolescent where you would only expect babies

[Admin]

Astronomers have discovered oxygen and heavy elements in the earliest galaxy ever seen, suggesting some galaxies as early as 300 million years after the Big Bang matured early.

Interesting report. I note this about z = 14.0 using cosmology calculator. My note, z = 14.0 using cosmology calculators show "It is now 13.722 Gyr since the Big Bang. The age at redshift z was 0.300 Gyr. The light travel time was 13.422 Gyr. The comoving radial distance, which goes into Hubble's law, is 10351.4 Mpc or 33.762 Gly...", https://lambda.gsfc.nasa.gov/toolbox/calculators.html

We cannot see JADES-GS-z14-0 using its comoving radial distance in GR. The galaxy if it still exists would be more than 33 Gly away. There is plenty of interpretation presented when analyzing observation like this. Example, "This early galaxy, designated JADES-GS-z14-0, has 10 times the amount of heavy elements that would be expected in a galaxy that existed just 300 million years after the Big Bang. The findings indicate that this galaxy was already mature in the early universe, challenging theories of galactic evolution."
