You need to know that I love your interest in physics. But the internet is broken. Reading articles on physics written by noobs still isn't fun. We need to change that.

On the topic I want you to notice that intial measurements of JWT on redshift of very distant galaxies is already being identified as a measurement error for most of them. JWT turns out to be more sensitive in the IR region than it was expected to be, causing some absorption lines to be misidentified, causing a very substancial error in redshift in those cases. Most of the galaxies discovered that appeared to be older than the model allows are now put into the very much younger category. Investigation is ongoing on every JWT finding, but making up conspiracy theories never helped science. Once scientist have concluded their work they will tell what is.

So far JWT hasn't identified anything which would render current cosmology theories totally wrong. There is no sensation.
