New James Webb Telescope Discoveries Challenge Early Universe Theories.
TL;DR Summary
The James Webb Space Telescope has discovered six massive galaxies that appear to have grown too quickly after the Big Bang, contradicting the current model of cosmology. If the masses and times since the Big Bang are confirmed, it could require fundamental changes to the reigning model of cosmology. The galaxies' masses and times are initial estimates and will need follow-up confirmation with spectroscopy.
