Computer simulations show that the standard model of cosmology isn’t, in fact, broken.

Faucher-Giguère is a member of a team led by Guochao Sun of Caltech, who together are performing simulations of how the first galaxies formed. They found that rather than being big, the galaxies observed by the JWST are luminous because they are seen during a"A system doesn’t need to be that massive," said Sun."If star formation happens in bursts, it will emit flashes of light. That is why we see several very bright galaxies.
Some examples of the distant, yet luminous for their era, galaxies found by the JWST. The ‘z’ number refers to their redshift – the higher the redshift, the farther back in time we see them, in this case 13.4 and 13.5 billion years ago, respectively.
