The large hadron collider, the world’s most advanced particle accelerator, has undergone a major revamp which scientists say could spark a physics revolution.
The vast machine, deep underground in the Swiss Alps, smashes atoms together to break them apart and discover what is inside them.
Since the upgrade, its instruments are more sensitive, allowing researchers to study the collision of particles from the inside of atoms in higher definition.
It means there’s now the best chance ever of the machine finding subatomic particles that are completely new to science.
The hope is that it will make discoveries that will spark the biggest revolution in physics in a hundred years.
The BBC’s science correspondent Pallab Ghosh reports.
