Dark energy and dark matter

Dark energy is gravitationally repulsive material that fills the entire space and acts against gravity . Dark energy increases the expansion of the universe by pushing the galaxies away from each other. Astronomers believe that 95 per cent of the mass of it consists of the dark matter. Dark matter is not visible to us because it emits no radiation and can be detected only by its gravitational pull on visible matter.
