Early galaxies are smaller than previously believed

The University of Texas at Austin — August 26, 2024, 09:00 PM UTC

Summary: A study published in the Astrophysical Journal reveals that early galaxies observed by the James Webb Space Telescope are less massive than initially thought. Researchers found that black holes contribute to their brightness, misleading estimates of their size. While the number of massive galaxies exceeds predictions, the standard model of cosmology remains intact. The study involved collaboration from multiple institutions and was supported by NASA and the National Science Foundation.

I'm replacing the original 8-factor scoring system with a new and improved one. It doesn't use the original factors and gives much better significance scores.
