Quizplus · Accepted Answer

When matter collides with anti-matter, they annihilate each other, releasing a large amount of energy in the form of photons. This is because when a particle and an anti-particle come together, they have opposite charges and spin, and when they annihilate, these properties must be conserved. The energy released in this process is equivalent to the mass of the particles multiplied by the speed of light squared, as described by Einstein's famous equation E=mc².
