An artists interpretation of two antiprotons interacting. (Image credit: Brookhaven National Laboratory)
For the first time researchers have measured the interaction between two antiprotons, a subatomic particle with the same mass as a proton, but with a negative electrical charge and the antimatter equivalent of the proton. The measurement shows the interaction between antiprotons is attractive, similar to how two magnets can be attracted to each other.
These findings bring science closer to understanding the structure and properties of the antinuclei, the antimatter equivalent of a nucleus of an atom.
