So for those who actually are interested in this topic I would recommend the YouTube video linked here for a good explanation.

The key point is that scientists had hypothesized the size of the very early galaxies in the Universe using models that included some initial parameters like energy density and gravitational forces. When they looked at the JWST pictures and saw these for the first time, they were “bigger” than expected. So, the Universe has the final word on what is “real” and the scientists just need to understand what parameters they got wrong when they built their models. Kind of like climate change that predicted much warmer temperatures than we are seeing now.
Predicting warmer temps and getting cooler temps really hurts the models.
Especially since there are 20 or more models and they all fail.
