Most of our univers is missing!!! Only a fourth is made up of Atoms. The universe is made up of mostly Dark matter and Dark energy. The difference between the two is Dark matter is only a different form off particals and Dark Energy is the undefinable amount of energy left to fill the universe. Dark energy has causes objects in space to defy the laws of physics causing the universe to expand rather than shrink or stay stable.
