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 ...

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 ...

Russia's state-owned Rosatom announced a prototype plasma engine which could speed up travel to other planets.

A huge detector in the Mediterranean Sea spotted the most energetic neutrino from space to date. The particle could shed light on the universe’s most extreme phenomena.

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. 10, 2025 — Entanglement -- linking distant particles or groups of particles so that one cannot be described without the other -- is at the core of the quantum revolution changing the face ...
