Matter is made up of small particles called atoms. Atoms can exist on their own or together as molecules. Atoms are very small and around 100,000,000 of them side by side would measure 1 centimetre.

The discovery of the Higgs boson was a triumph for the standard model of particle physics. This is the theory that describes reality at the level of elementary particles and the forces between them ...

Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...

A completely new type of fundamental particle may explain the mystery of 'dark matter', the missing material that makes up more than 80 per cent of the universe's mass, according to British scientists ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most ...

Dark matter, as far as scientists can tell, is present all throughout the Milky Way galaxy. The mystery substance appears to give the galaxy more mass than astronomers can observe, meaning it is ...

Dark matter accounts for approximately 85 percent of all the mass density in the known Universe. The elusive substance is “dark”, meaning scientists cannot detect or interact with it in any meaningful ...

A completely new type of fundamental particle may explain the mystery of “dark matter”, the missing material that makes up more than 80 per cent of the universe’s mass, British scientists believe.
