Unraveling the Mystery: James Webb Telescope Sheds Light on "Impossible" Galaxies at Cosmic Dawn

New research using computer simulations suggests that the early galaxies observed by the James Webb Space Telescope may appear mature and bright due to irregular bursts of star formation, rather than being uncharacteristically massive. The simulations were able to reproduce the same number of bright galaxies observed by the telescope, without contradicting existing cosmology theories. This phenomenon, known as "bursty star formation," involves the rapid formation of stars followed by stagnant periods before another burst. The study provides insights into the early universe and challenges previous assumptions about galaxy formation.
