Dark Matter

Dark Matter is referred to the hypothetical matter that scientists have not been able to locate in the universe - either through telescopes or using any other technological method. 27% of the matter in the universe is said to be dark matter. Its existence came to the fore because of its gravitational effects on matters that are visible in the universe. Scientists have been unable to directly observe dark matter since they do not emit light or energy. The universe is made up of baryonic matter. This consists of electrons, protons, and neutrons. Dark matter on the other hand, could be made of both baryonic and non-baryonic matter. Despite many speculations regarding the existence of dark matter, no one can clearly define what dark matter is made of.
