Dark matter may be invisible to light, but it can still be detected, through its gravitational interactions. Specifically, it can be detected:
* By the fact that galaxies rotate way too fast, for the amount of known matter.
* By gravitational lensing.
Galaxies are vast collections of stars, gas, dust, and dark matter, and they are the fundamental building blocks of the visible Universe. Clusters of galaxies consist of groups of galaxies bound together by gravity, showcasing the large-scale structure of the cosmos. Together, these galaxies and their clusters form a complex web-like arrangement known as the cosmic web, which defines the distribution of visible matter in the Universe. This structure helps astronomers understand the evolution and dynamics of the Universe over time.
Clusters of galaxies form due to the gravitational attraction between individual galaxies in a region of space. Over time, these galaxies are pulled together by their mutual gravity to create a cluster structure. The largest clusters are held together by dark matter, which provides the majority of the mass in the system.
Probably not. Dark matter is not believed to concentrate well in or around masses the size of stars. But it does concentrate well around galaxies and clusters of galaxies. Most of the mass of a galaxy like ours is believed to be in a sphere of dark matter in the galaxy's spherical halo.
Diffuse clusters are large, loosely bound groups of galaxies that exhibit a lower density of galaxies compared to more compact clusters. They are characterized by their extended, diffuse distribution of galaxies and often contain significant amounts of dark matter and hot gas. These clusters play a crucial role in understanding the large-scale structure of the universe and the processes of galaxy formation and evolution. They can also provide insights into the nature of dark energy and cosmic expansion.
Gravity is the primary force involved in the formation of galaxies after the big bang. Over time, the gravitational attraction between matter caused it to clump together, forming structures like galaxies and clusters of galaxies.

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.
Galaxies form clusters due to the gravitational attraction between them, which pulls galaxies that are relatively close together into groups. Over time, these gravitational interactions can lead to the merging of smaller clusters into larger ones. Additionally, the presence of dark matter plays a crucial role in providing the necessary gravitational framework to hold these clusters together. Clusters are often located in regions of higher density in the universe, where the overall gravitational pull is stronger.

Galaxies. They are just about the same now as they were then. 14 Billion years ago, astronomers believe that the "Big Bang" created matter from energy, which is how they believe galaxies were formed.
Globular clusters are vital to our understanding of the universe because they contain some of the oldest stars, offering insights into the formation and evolution of galaxies. Their dense populations of stars allow astronomers to study stellar evolution and dynamics in a controlled environment. Additionally, globular clusters can serve as laboratories for testing theories of dark matter and the early universe, helping to unravel the mysteries of cosmic history.
Wherever you look, galaxies and galaxy clusters are observed to have much more mass than the sum of the known matter (stars, dust, gas, black holes). Galaxies rotate too fast for the known amount of matter, galaxies in a galaxy cluster move too fast, and gravitational lensing indicates a larger mass than the known masses.Wherever you look, galaxies and galaxy clusters are observed to have much more mass than the sum of the known matter (stars, dust, gas, black holes).

Galaxies were made by God from the beginning of time.Answer:The scientific opinion is that galaxies result from the gravitational attraction of matter into stars and the interactions of the stars to form clusters of swirling stars.. The matter originated in the "Big Bang" that was the beginning of the Universe some 15 billion years ago.
