According to a large international team of physicists, the attractive force between antiprotons is similar to that between protons. A new measurement by the STAR collaboration reveals that the force between antiprotons (p) is attractive and strong. Image credit: Brookhaven National Laboratory. The team, called the STAR collaboration, measured two key important parameters: the scattering length and the effective range of interaction between two antiprotons....

Upper image: 3D diagram of the magnetic wormhole, showing how the magnetic field lines (red) leaving a magnet on the right pass through the wormhole. Bottom: in terms of magnetism the wormhole is undetectable, which means that the magnetic field seems to disappear on the right only to reappear on the left in the form of a magnetic monopole.
