Dark Matter is a non-baryonic and unobservable form of matter that accounts for nearly 85% of the matter in the universe. Its name derives from the fact that it does not appear to interact the entire electromagnetic spectrum including light, making it extremely difficult to detect it using any astronomical equipment. The reason more information cannot be obtained about them is because they may be primary composed of some as-yet undiscovered subatomic particles. Scientists believe that it has a strong influence on the universe’s structure and evolution. They conclude the existence of dark matter because it has been revealed that many galaxies would fly apart instead of rotating without their presence. Certain galaxies would not have even formed so without the presence of huge chunks of matter present in them. Dark Matter does not interact with normal matter the same way we believe it to. In the standard Lambda-CDM model of cosmology the total mass–energy of the universe 26.8% of the universe is dark matter.
