NASA’s new telescope has captured images of six giant galaxies that have existed since the beginning of the universe. of these galaxies It is larger and more developed than the Milky Way. popped up. This discovery also supports previous studies.

To understand how these galaxies formed, scientists have a stress test they applied. This test explain what we know about the universe showed that we need to find something new, or so say scientists.

“Maybe the universe is expanding faster than we thought after the big bang.”

Mike Boylan-Kolchin, a professor at the University of Texas and author of a paper published in the journal Nature Astronomy, says: “If the masses of these galaxies are correct, then there’s something we don’t know. We need a new idea of ​​galaxy formation or cosmology. Maybe the universe is expanding faster than we thought after the Big Bang, and that means new forces and particles.”

Professor Boylan-Kolchin’s article “Stress testing for ΛCDM with candidates for high redshift galaxies” bears the title. ΛCDMis the standard model of cosmology, which includes dark energy and cold dark matter.

The unusual thing about the observed galaxies is that they have converted most of their gas into stars. Normally galaxies only 10% turns into stars. This is an unexpected deviation, although theoretically possible.

No matter how far we as humanity think we have come in science, the universe strikes again and again that we are not ready for anything…
