What Is Dark Matter | Hire A Healer

Dark matter is a hypothetical and invisible form of matter that does not interact with light or other electromagnetic radiation. It is thought to serve as gravitational scaffolding for cosmic structures, and its presence is inferred through its effects on the formation and evolution of galaxies, gravitational lensing, and the observable universe's current structure. Vera Rubin provided significant evidence for the existence of dark matter through her observations of galaxy rotation curves. For example, the Bullet Cluster is a famous example of a galaxy cluster that is thought to have formed through the collision of two smaller clusters, with dark matter playing a crucial role in the formation of the cluster.
