No, not all particles annihilate with photons. Particle annihilation refers to the process in which a particle and its corresponding antiparticle collide and convert their mass into energy, typically resulting in the emission of photons. This process follows the principle of conservation of energy and conservation of momentum.
Photons, being particles of light, do not possess mass. Therefore, when a particle and its antiparticle collide and annihilate, they can produce photons as a result of the conversion of their mass into energy.
However, it is important to note that not all particles have corresponding antiparticles. Only certain particles, such as electrons and positrons (the antiparticles of electrons), have well-defined antiparticles. When an electron and a positron collide, they can annihilate each other and produce photons.
For other particles that do not have antiparticles, such as protons, neutrons, or neutrinos, annihilation with photons does not occur. Instead, these particles can interact with photons through other processes, such as scattering or absorption/emission, depending on their specific properties and interactions with electromagnetic fields.
