TL;DW: James Webb is already completely upending our models of cosmology, and it hasn't even really tried yet:

I wanna point the thing at the edge of universe for 12 days, not just 12 hours like was used for the first Webb deep field. Just to see if any ghosts come up out of the noise floor. But I doubt that will happen for a looooong time, because telescope time is precious, and there are many other low-hanging fruit objectives to tick off in the meantime.

Dear god, does this thing fucking work.
