Gravitational Instability Model

The Gravitational Instability Model explains how structures in the universe, like galaxies and clusters, form from tiny irregularities in the early universe's matter distribution. Small regions with slightly more matter experience stronger gravity, pulling in more material over time. As these regions grow denser, gravity causes them to collapse further, leading to the formation of galaxies and larger cosmic structures. Essentially, slight initial differences in density are amplified by gravity, transforming a relatively uniform universe into the complex web of galaxies we observe today.
