Great news. Finding stuff that doesn't fit into the current model and we need smart people to get to work understanding may be the surest sign that the JWST is invaluable.
Not only because it means we're about to learn some big stuff, but also because it would be completely *preposterous* if humans at our puny stage of development had already correctly figured out every last detail about insanely complex things like the exact size, age, and origin and age of galaxy-sized things that developed tens of billions of years ago, billions of light-years away from the tiny rock we stand on. Getting things wrong shows that people are actually doing science honestly!
How can a human at this puny stage know this?
It seems much more likely that we are not missing a formula but a basic understanding of reality. Much like the early astronomers trying to find a formula for the movement of the sun and planets that put Earth at the center of the universe

I remember some billionaire saying 15% of the decisions you make each day should be mistakes otherwise your not trying and you're not learning.
