UNIVERSE

1.     Ordinary matter in the Universe is about ~4% of the total Universe, By ordinary matter  means we(human), planets, stars, galaxies etc.

2.     Nearly 26%  i.e. one fourth of the matter in the Universe is of Dark matter.It is some time called as Invisible matter because it doesn’t emit in Electromagnetic spectrum, it doesn’t reflect, it doesn’t interact with electromagnetic spectrum. So the question arises that how we came to know that there is dark matter in the universe? We came to know through it gravitational effect.

3.     Rest of the pie is of Dark energy.
