The universe is everything and anything that exists and The universe is still a mystery to scientists. The universes is made up almost entirely of hydrogens and heliums. These are the two lightest elements. All the rest of the matter in the universe is very rare. Elements such as silicon, carbon and other concentrated into clouds, stars and planets. Gravity and electromagnetism are the two familiar forces. The other two kinds are strong and weak nuclear forces. These operate only inside the incredibly tiny nuclei of atom, holding the tiny particles together.
The large hadron collider, successfully tested in 2010 will teach us more about particle acceleration and the birth of stars and the deepest laws of nature.
