Dark Matter: invisible mysterious element; composition unknown; may stop Dark Energy to rip our universe apart

Hubble Telescope not only sees the stars and galaxies but also shows us a path to measure an invisible element of cosmos called DARK MATTER. This can stop DARK ENERGY. Dark Matter is also known as cosmic glue is a positive force because it attracts other objects with its gravity. Dark Matter is responsible for producing galaxies in our universe. Gravity of atoms alone cannot produce these galaxies in finite amount of time. And we wouldn't be here today if there was no Dark Matter.
