The gravitational attraction of the mass in the galaxies comprising the cluster.
Galaxies clump together in clusters and superclusters due to the force of gravity. Gravity pulls galaxies towards each other, causing them to form groups and larger structures. This clustering is a natural result of the way matter is distributed in the universe.
They form galaxies, galactic clusters, and galactic superclusters.
Ten superclusters.
Gravitational force (or gravity) is a force that pulls things together.
Actin is thin, pulled together by myosin.

Such groups exist at different levels:* Star clusters * Galaxies * Galaxy clusters * Superclusters

Gravity is the force that pulls dust and gas together in space. The gravitational attraction between particles causes them to clump together, eventually forming larger structures like stars and planets.
The force is called magnetism.
The force that pulls masses together is gravity. It is a fundamental force of nature that acts between all objects with mass, causing them to be attracted to each other.
