There are certain things beyond the universe that we never thought of. One of those things is the ‘Dark Matter’ mystery. It exposes the very birth of our universe .Dark matter is the ultimate key to the fate of our Universe.
Dark matters are nothing but a form of matter which doesn't interact with light but their only form of interaction is gravitationally. The name only refers to the fact that it doesn't appear to interact with observable electromagnetic radiation thus remain invisible to the entire electromagnetic spectrum. This makes it extremely difficult to be detected by current technologies .This form of matter is better known as "Invisible Matter" .Dark Matter is classified as cold , warm or hot according to the velocity with which it moves throughout the universe. Dark Matters account for a significant part of the universe unlike the visible matter which makes up for the minority part of the universe .
No one has been able to exactly predict the characteristics of dark matter or proven it’s existence with existing technologies. But scientists have predicted the existence of it as it effects the universe in peculiar ways.
What is the significance of dark matter? It is often said by the experts that the universe would have been in a different state unlike today. It is also said that it is due to this dark matter that the stars and planets in a galaxy are held together and are not thrown apart from each other. Even the theories related to dark matter explain the formation of big cosmic structures in the universe such as galaxies and cluster of galaxies. It is the binding force of the universe.
The primary evidence for dark matter are the calculations that show that many galaxies would have flown apart instead of rotating or would not have formed or move as they do today if they did not contain a large amount of unseen matter.
Other lines of evidence included observation in gravitational lensing, from cosmic microwave background ,from astronomical observation of the observable universe's current structure ,from the formation and evolution of galaxies ,from mass location during galactic collisions ,and from the motion of galaxies within galaxy clusters.
