What is Dark Matter?

Dark matter is an invisible and mysterious substance that makes up a significant portion of the total mass of the universe. Its existence is inferred through its gravitational effects on visible matter, such as stars and galaxies. The concept of dark matter was first proposed in the 1930s by Swiss astronomer Fritz Zwicky, who observed that the mass of galaxy clusters was not sufficient to account for the gravitational forces holding them together.

Theories of Dark Matter

Various theories have been proposed to explain the nature of dark matter. One popular theory is that dark matter is composed of weakly interacting massive particles (WIMPs) that interact only through gravity and the weak nuclear force. Another theory is that dark matter is made up of axions, which are extremely light particles that interact very weakly with other matter.
