Dark matter is a hypothetical form of matter that scientists believe exists because of its gravitational effects on visible matter. It doesn't interact with light or other forms of electromagnetic radiation, which is why it is referred to as "dark." Despite being invisible, it is thought to make up a significant portion of the total mass in the universe, estimated to be about 27% of the total matter. Dark matter is not composed of the particles that make up the visible matter we can see, such as electrons, protons and neutrons, but scientists think it could be composed of other, as yet undiscovered, particles. The existence of dark matter is inferred from its effects on visible matter, such as the motion of stars and galaxies, and it is a key component in our understanding of the universe and its evolution.
