NASA's James Webb Space Telescope has captured images of six giant galaxies that have existed since the beginning of the universe. These galaxies turned out to be larger and more advanced than the Milky Way. This discovery also supports previous studies.

Scientists used a stress test to understand how these galaxies were formed. This test showed that we need to find something new that could explain what we know about the universe, or so scientists say.

Mike Boylan-Kolchin, a professor at the University of Texas and author of a paper published in Nature Astronomy, says: "If the mass of these galaxies is correct, there's something we don't know. We need a new idea about galaxy formation or cosmology. Perhaps The universe is expanding faster than we thought after the Big Bang, and that means new forces and particles."

Professor Boylan-Kolchin's article is titled "Stress test ΛCDM with high redshift galaxy candidates". ΛCDM is the standard model of cosmology that includes dark energy and cold dark matter.

The unusualness of the observed galaxies is that they have converted most of their gas into stars. Normally, galaxies convert only 10% of their gas into stars. This is an unexpected deviation, although theoretically possible.
So, contrary to what we humans think, the universe says that we are not ready for everything yet.
