True - Z=16 redshifted galaxy in JWST is shown very red, meaning actual shift is even greater, because should be calculated when shown as "white". Like our sunlight is visible at 380-700 nm range, Z=16 corresponds to the originally UV lower edge, and JWST does not catch the longer edge - limitation of the tool perhaps. Actual Z would be in the middle of the lower edge and its almost double — something like Z=(16+2*16)/2=24. And another group of astronomers found Z=20 galaxy when looked through the area with strong gravitational lensing - which helped in bypassing/enhancing angular resolution limitation of JSWT tool. Meaning JWST has couple of limitations to stay around Z≤15 not to break Big Bang speculation. But now it is broken.

Big Bang was debunked recently, and static Universe rehabilitated, based on Time Dilation alone, in the first chapter of free eBook “Time Matters” at https://www.amazon.com/dp/B0B38M5PRL or

What’s next? — JWST will release spectroscopic data (on metallic, i.e. everything heavier than hydrogen, content of remote objects), and Eric Lerner , “The Big Bang Never Happened” author and spectral expert, will jump on it to expose billion years old galaxies, by metals in their stars, in the alleged 100–300 million old Universe.
