1. When antimatter annihilates with matter, an enormous amount of energy is released. According to Einstein's mass-energy equivalence equation E=mc², the annihilation of antimatter converts its mass into energy.
2. Scientists have estimated that the energy released from the annihilation of one millionth of a gram of antiprotons with protons is equivalent to that of 37.8 kilograms of TNT explosive.
3. The energy released from the annihilation of one gram of antimatter is approximately equal to the energy equivalent of four tons of TNT, which is comparable to the energy released by the atomic bomb dropped on Hiroshima.
4. The energy released from the annihilation of five kilograms of antimatter is roughly equivalent to the energy equivalent of two hundred million tons of TNT, demonstrating the immense power involved.
5. To date, the antiparticles of most known particles have been discovered, but the antiparticles of photons and neutrinos have not been confirmed to exist. Physicists believe that antiphotons do not exist because photons themselves may be their own antiparticles. The detection of the antineutrino is challenging because it may have too small a mass to be easily observed.
6. When a particle and its antiparticle meet, they usually annihilate each other and release gamma rays. However, under certain conditions, such as when high-energy electrons and positrons collide, they can produce a Z boson.
7. In the most basic scenario, the annihilation of a particle and its antiparticle results in the complete conversion of mass into energy. They release all their energy and are mutually annihilated, simultaneously emitting two beams of gamma rays in opposite directions to maintain momentum conservation.详情
