Dark matter constitutes a significant portion of the universe, particularly concentrated at the centers of galaxies and proto-galaxies. This concentration leads to dark matter annihilation, driven by gravitational forces, underscoring its fundamental role in galactic structure. As one moves away from the center, the density of dark matter decreases. Dark matter is not just an accessory; it significantly exceeds visible matter, akin to froth on an ocean, shaping the gravitational landscape. The movement of stars around the galactic center is sustained by dark matter, which provides the necessary gravitational grip to prevent stars from being ejected into space. Historical studies like those by Robert Rubin have demonstrated that the speeds of stars suggest a substantial hidden mass is at play, making dark matter crucial for the stability and cohesion of galaxies like the Milky Way. This highlights a profound reliance on dark matter, suggesting that our understanding of the universe is predicated on this elusive substance.
