Dark matter is a hypothesized kind of stuff that is considered to make up around 85% of all matter in the cosmos. Its presence is hinted at in a number of astronomical measurements, including gravitational phenomena that cannot be explained by established gravity theories unless more matter is present than can be observed.

As a result, most scientists believe that dark matter is prevalent in the universe and has had a significant impact on its structure and development. Because dark matter does not appear to interact with the electromagnetic field, it does not absorb, reflect, or emit electromagnetic radiation, making it difficult to detect.
