All Antimatter eventually meets the same fate: annihilation.
- A lot of energy is released in the process, and annihilation is the most efficient way to generate energy, as 100% of the mass is converted into energy, as opposed to the ~1% of nuclear energy.
- An Electron and Positron can collide, and annihilate one another. They decay into two opposite direction Photons, in empty space to conserve momentum.
- If there is matter that transfers energy, then it could be a single photon.
