They are worried that the galaxies they keep finding with the James Webb Space Telescope shouldn't exist. The scientist warned us. The galaxies were as mature as our own Milky Way and they come from the beginnings of the universe. There's billions of celestial objects - sounds like an overwhelming panic.

Galaxy formation is under the "microscope". There might be something wrong with the dark energy and cold dark matter paradigm that has been guiding cosmology for decades.
Just how do you go about changing your understanding of the cosmos and how galaxies grow? That's an exciting proposition.

There's a lot going on in this field.
