Friends I think everyone is familiar with dark matter in this technological world. Till now we all study about Solid Matter, Liquid Matter and Gaseous Matter. But here a new matter that is caled as dark matter. Now infinite questions arises in our mind that what is dark matter, how it forms, where it is present and what is the role of this matter. Now let me xplore actually what it is.

What Is Dark Matter? 

According to experts, Dark Matter is a form of matter which is abundant in the Universe, that's why it has a strong influence on its structure and evolution.

Dark Matter is called Dark because it does not appear to interact with the electromagnetic field, it means that Dark Matter does not absorb, reflect, or emit electromagnetic radiation.

In a simple way, we can say that Dark Matter is a form of matter that cannot absorb, reflect, or emit electromagnetic radiation.  

Is Dark Matter Exists or Hypothesis till Now?

According to experts, Dark Matter constitutes 85% of the total mass. Dark Matter has not observed directly till now, it's just a hypothesis. If dark matter exists, it must hardly interact with baryonic matter and radiation. Some experts thought that most dark matter is non-baryonic in nature, it may be composed of such subatomic particles which is yet been undiscovered.

Composition of  of Dark Matter

Most scientists think that dark matter is composed of non-baryonic matter. The lead candidate, WIMPS (weakly interacting massive particles), are believed to have ten to a hundred times the mass of a proton, but their weak interactions with "normal" matter make them difficult to detect. Neutralinos, massive hypothetical particles heavier and slower than neutrinos, are the foremost candidate, though they have yet to be spotted. (source taken from space.com)
