Dark Matter is a mysterious invisible substance that makes up 85% of matter in universe. Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation.
Dark matter is a material that cannot be seen directly but we know that it exists because of the gravitational effect it has on the light coming from the objects that we can observe directly. In 1997, a Hubble Space Telescope image revealed light from a distant galaxy cluster being bent by another cluster in the foreground of the image.
Based on the way the light was bent, scientists estimated the mass of the foreground cluster to be 250 times greater than the visible matter in the cluster.
Scientists believe that dark matter in the cluster accounts for the unexplained mass. And the way it bends the path of light as it moves through it, Scientists called this effect “Gravitational Lensing”.
