What Is Dark Matter | Elf Dolls

Dark matter is a hypothetical form of matter that does not interact with light or other electromagnetic radiation. The cosmic microwave background radiation is a key area of study in cosmology related to dark matter. Dark matter is thought to have played a crucial role in the formation of the first stars and galaxies. The properties of dark matter are still not well understood, but scientists believe that it may be composed of WIMPs or other exotic particles.
