Quantum entanglement is a fascinating phenomenon where two particles’ states are tied to each other, no matter how far apart the particles are. In 2022, the Nobel Prize in Physics was awarded to Alain ...

Le troupeau de moutons du CERN en 2017. (Image : CERN) L'intrication quantique est un phénomène fascinant où les états de deux particules sont liés l'un à l'autre, quelle que soit la distance qui les ...

After several years of intense work, CERN and international partners have completed a study to assess the feasibility of a ...

Au terme de plusieurs années de travail intense, le CERN et des partenaires internationaux ont achevé une étude visant à ...

In 1929 the American astronomer Edwin Hubble discovered that the distances to far-away galaxies were proportional to their redshifts. Redshift occurs when a light source moves away from its observer: ...

In the 1860s, James Clerk Maxwell recognized the similarities between electricity and magnetism and developed his theory of a single electromagnetic force. A similar discovery came a century later, ...

At CERN, we probe the fundamental structure of the particles that make up everything around us. We do so using the world's largest and most complex scientific instruments. Physicists and engineers at ...

Invisible dark matter makes up most of the universe – but we can only detect it from its gravitational effects Galaxies in our universe seem to be achieving an impossible feat. They are rotating with ...

Earth is subject to a constant bombardment of subatomic particles that can reach energies far higher than the largest machines A photomicrograph shows where high-energy electrons blazed through a film ...

An international collaboration is developing a future high-energy machine to collide electrons and positrons head-on at energies up to several TeV The Compact Linear Collider (CLIC) is a proposed ...

Wojciech Brylinski was analysing data from the NA61/SHINE collaboration at CERN for his thesis when he noticed an unexpected anomaly – a strikingly large imbalance between charged and neutral kaons in ...
