The unprecedented energy of proton collisions at the LHC could be what scientists need to find a possible substructure for subatomic particles
Earth is subject to a constant bombardment of subatomic particles that can reach energies far higher than the largest machines
Invisible dark matter makes up most of the universe – but we can only detect it from its gravitational effects
Extra dimensions may sound like science fiction, but they could explain why gravity is so weak
CERN physicists collide heavy ions to free quarks - recreating conditions that existed in the universe just after the Big Bang
CERN scientists are probing the fundamental structure of the universe to find out what the elementary particles are and how they interact
Supersymmetry predicts a partner particle for each particle in the Standard Model, to help explain why particles have mass
All matter in the universe was formed in one explosive event 13.7 billion years ago – the Big Bang
The big bang should have created equal amounts of matter and antimatter. So why is there far more matter than antimatter in the universe?
Elementary particles may have gained their mass from an elusive particle – the Higgs boson
The Standard Model explains how the basic building blocks of matter interact, governed by four fundamental forces
The Z boson is a neutral elementary particle which - along with its electrically charged cousin, the W - carries the weak force
Will we see a unification of forces at the high energies of the Large Hadron Collider?
The W boson carries the weak force. It changes the character of particles of matter—allowing the Sun to burn and new elements to form
