Astronomers found two colliding galaxies dating back to less than 500 million years after the big bang
Analysis: The discovery of these early well formed galaxies has disrupted the current cosmology. Web References https://www.scientificamerican.com/article/earliest-merging-galaxies-discovered-in-new-jwst-photos/
A cosmic collision that may be the oldest galaxy merger ever seen has appeared in images from the James Webb Space Telescope (JWST). The photographs reveal ancient galaxies close to crashing into each other during the first 500 million years after the birth of the universe. This merger appears to beat the former record holder by a full 300 million years. The observation is described in two papers—one published in the Astrophysical Journal Letters in early June and another currently under peer review—both led by Tiger Yu-Yang Hsiao, a graduate student at Johns Hopkins University.
