Back in February, the James Web Space Telescope looked back to the  
supposed dawn of time just 600 million years after the big bang and  
found six galaxies that were far larger, better developed, and more  
modern-looking than the current big bang-Lambda-CDM model of cosmology  
predicts. That means that full-fledged galaxies complete with star  
systems and supermassive black holes formed in the early universe in  
less time than it takes the Milky Way to rotate three times. While  
some of these galaxies might turn out to be quasars, that would still  
mean that supermassive black holes were present in the earliest epochs  
of the universe, and that would turn what we know of black hole  
formation on its head.

Cosmology was already on the ropes with the previously discovered  
Hubble tension (discrepancy) in the estimates of the Hubble parameter  
(constant) between measurements made of distant galaxies by the Hubble  
telescope and measurements of the cosmic microwave background (CMB)  
made by the Planck satellite. So this most recent revelation is akin  
to a knockout punch to cosmology and does break our theories about the  
universe.
