"JWST Unveils Abundance of Early Galaxies, Rewriting Cosmic Evolution Theories"

Astronomers using the James Webb Space Telescope (JWST) have discovered that galaxies resembling our Milky Way are more common in the early universe than previously believed. These disk-shaped galaxies, which rotate about their centers and often have spiral arms, were thought to be too fragile to exist during the early universe when galaxy mergers were more common. However, the new research overturns this understanding, revealing that these Milky Way-like galaxies formed as early as the beginning of the universe. This finding challenges existing theories of cosmic evolution and suggests a need for new ideas in understanding galaxy formation and the role of dark matter.
