The observations suggest that galaxies in clusters evolve from spirals to ellipticals over the course of about 5 billion years.

According to Bertolami, a variable gravitational constant readily explains why galaxies in clusters are being whirled around so rapidly: the individual galaxies attract each other more strongly than predicted by Newtonian gravity.

Astronomers recently tracked dark matter's location within four colliding galaxies in this cluster by using a phenomenon known as gravitational lensing (the bending of light as it passes near massive objects).

Alternatively, the quenching could be caused by interactions with other galaxies in the cluster.

Fritz Zwicky used it for the first time to declare the observed phenomena consistent with dark matter observations as the rotational speeds of galaxies and orbital velocities of galaxies in clusters, gravitational lensing of background objects by galaxy clusters such as the Bullet cluster, and the temperature distribution of hot gas in galaxies and clusters of galaxies.

Much like is done in measuring the masses of galaxies from the motions of the stars and gas clouds in them, you can use the motions of the galaxies in the clusters to measure the masses of the galaxy clusters.

This statement is certainly true if we assume that the only gravitational force present is that exerted by visible matter, but it is true even if we assume that every galaxy in the cluster, like the Milky Way, is surrounded by a halo of dark matter that contains 90 percent of the mass of the galaxy.»
