Particle physics

Physicists believe a new experiment could prove their existence and answer fundamental questions about our Universe.

Positronium has the potential to revolutionise physics but the elusive substance had been too hot to handle.

Researchers want a new, much bigger supercollider but is it worth us paying the £12bn price tag?

The elusive substance holds the key to discovering how the Universe was formed.

Physicists believe that an unknown force could be acting on sub-atomic particles known as muons.

An extraordinary image of ghost particles in the Milky Way is captured by an observatory buried at the South Pole.

They hope they will help us understand the "strong force" that holds the insides of atoms together.
