Mathematical equations have shaped our understanding of the universe, and these nine have played a key role in changing the world.

Neutrinos are ghostly subatomic particles that can travel in a straight line for billions of light-years, passing unhindered ...

The neutrino was 30 times more energetic than any other previously observed particle of its kind. Scientists still don’t know ...

Carnegie Mellon University's Professor Curtis Meyer and his research colleagues explore an uncharted world inside protons and ...

The team announced its “ultrahigh energy” neutrino on Wednesday, in a paper published in the journal Nature. The finding ...

Researchers have been working for decades to understand the architecture of the subatomic world. One of the knottier questions has been where the proton gets its intrinsic angular momentum, otherwise ...

Density describes how closely packed the particles are in a solid, liquid or gas. There is little difference between the density of a liquid and its corresponding solid (eg water and ice).

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 end to end would measure 1 centimetre.

Feb. 6, 2025 — A team of international researchers has developed an innovative approach to uncover the secrets of dark matter in the cosmos. They are searching for dark matter using atomic ...
