Our understanding of the universe changes all the time as we gain more information. I find this rationale approach very good, but it can also be really frustrating when debating the origins and composition of the universe with someone who takes theories as "categorical" truths.

This seems to be specifically about our understanding of the expansion of the universe (from the big bang).

It also throws a wrench into "there is no center, expansion is the same everywhere."

I know this is about a fundamental physics question, but what jumps out at me is that JWST can resolve individual Cepheids at 130m light years distance !!! What an incredible marvel of engineering.

I cannot wrap my head around the idea Giant Magellan Telescope will have at least four times the resolution (in some situations up to 20x) as JWST in a few years

Now they need to build a second JWST and send it to opposite side of solar system for Very Long Baseline Interferometry :-)
