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: ...

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

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 ...
