USA: The James Webb Space Telescope has raised some questions among scientists because it keeps discovering galaxies that "shouldn't exist."

Recent discoveries made by NASA's powerful James Webb Space Telescope about a few far-off galaxies have prompted doubts about our understanding of the cosmos as it exists today.

Given their location in the universe, these galaxies seem to be more developed and massive than one might anticipate. This unexpected finding led researchers to reconsider some fundamental ideas about cosmology and galaxy formation.

Mike Boylan-Kolchin of the University of Texas at Austin is leading new research that aims to "test" these galaxies in order to learn more about their makeup. According to Boylan-Kolchin's paper, the observed data pose a serious challenge to the widely accepted theory of dark energy and cold dark matter, which serves as the foundation for our current understanding of cosmology.

Galaxies typically turn about 10% of their gas into stars. To fit the current model, these recently found galaxies would have to turn almost all of their gas into stars. Although this theory is theoretically feasible, it deviates from the accepted scientific wisdom.

If the masses of these galaxies are accurate, it may be necessary to revise our understanding of the universe's expansion after the Big Bang, which would indicate a faster rate of expansion. To adequately explain the observed phenomena, it might be necessary to include new forces and particles.

To validate these results and pinpoint the precise causes of this discrepancy, more investigation is required. The observations may not be accurate, or supermassive black holes may be responsible for the apparent presence of more massive galaxies. Additionally, galaxies may appear older than they actually are in images, which can be deceptive.

Scientists will reassess their knowledge of the universe and the evolution of galaxies if the hypothesis is validated. This demonstrates the dynamic nature of scientific inquiry and our ongoing quest for knowledge about the cosmos.
