annihilation signatures

Annihilation signatures are signals produced when particles and their corresponding antiparticles, such as electrons and positrons, collide and destroy each other. This process releases a burst of energy, often in the form of gamma rays—high-energy light. By detecting these gamma rays, scientists can identify where such annihilations occur, which can help study phenomena like dark matter, cosmic rays, or exotic particles in space. These signals serve as a cosmic fingerprint, providing clues about processes happening in the universe that involve matter meeting antimatter.
