Matter....
As we know that matter is all around us .
Trees ,Plants ,Humans ,Earth ,Star and Universe
These all are made from matter
But this is true that in whole universe only 5% matter exists.
This means  everything we are watching all of that is only 5% of the total universe
And other universe is 95% .In which dark matter and dark energy exists
There is 20% dark matter and 75% dark energy .
To know more about Dark Matter watch video till end.
 
 
 
 
 
AS i told in the starting of the video
Normal matter is only 5% in the entire universe
But amount of dark matter is 20%.
Now the question arises ,what is dark matter and how is dark matter different from normal matter
When scientists studying about the universe then they found that
there is not enough mass  in the universe for obtaining that amount of gravity which holds  the galaxy
Scientists found in their calculation that for this amount of gravity we need many times more mass
Scientist named it DARK MATTER.
This matter is much different from normal matter .such as this matter is invisible.
There is only one similarity between dark matter and matter is that both affects gravity
Wherever the concentration of dark matter is more at that place light bends
But we don't know what is dark matter
But we know that what dark matter not is ?
First.....
This dark matter is not antimatter
because when antimatter touch normal matter it releases gamma energy
If you want to know about antimatter video link is in description
Second....
This dark matter spreads all around the universe.
and Third....
This dark matter is not black hole
If you don't know about black hole the video link is in description
We only know three thing about the dark matter.
First.....
Dark matter is something
Second....
Dark matter affects gravity
and Third.....
Dark matter is in excessive amount. Research on Dark matter is carry on by scientist
And may be in future we shall know what dark matter is.
