Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The galaxies. are observed in the optical (shown in orange and white). Most of the normal mass in the clusters (pink) is associated with gas heated in their collision. Dark matter is not visible, … Dark matter is a hypothetical invisible mass thought to be responsible for adding gravity to galaxies and other bodies. Since the amount of visible material in galaxies can't account for their shapes, distributions, and movements, astrophysicists argue there must be a form of mass yet to be discovered.
