Do these six galaxies destroy cosmology? No. Obviously.
"These six galaxies break cosmology!" scream the headlines. Yeah, nah — yeah, astronomers have found some galaxies in the JWST data that are crazy old, and yet seem to be just way too big. But nah: this doesn't mean cosmology is broken. As usual, the scientists ignore the click-baity headlines, roll their eyes and get on with figuring it all out. Plus, what time is it on the Moon? Not a simple question.
