The freshly-completed upgrade of the detectors and the harvest of Pb–Pb collision data expected in Run 3 will further improve the measurements.

Do particles and their antiparticles behave in the same way? Even tiny differences could be amplified over astronomical distances to produce very large effects. Read article 'Linear collider physics: ...

Until now, ultra-luminous X-ray sources (ULXs) were thought to be black holes, because their high luminosity implied a mass exceeding by far the maximal mass of a neutron star. The most luminous of th ...
