mangothode said:What equipment one can use to detect interaction between two massless particles, such a photons? Is that even possible?
The interaction between two massless particles is typically detected through the use of detectors or sensors that are able to measure changes in energy, momentum, or direction of the particles. This can be done through various experimental techniques such as collision experiments or high-energy particle accelerators.
Yes, massless particles can interact with matter through various fundamental forces such as gravity, electromagnetism, and the strong and weak nuclear forces. These interactions can be observed through the effects of these forces on the particles' properties.
Some common methods used to detect massless particles include scattering experiments, which involve colliding particles and measuring the resulting scattered particles, and radiation detection techniques, which utilize the energy or radiation emitted by the particles.
The interaction between two massless particles can be distinguished from the interaction between two massive particles through their different behaviors and properties. Massless particles, such as photons, travel at the speed of light and do not experience changes in energy or momentum, while massive particles, such as protons, have a finite speed and can experience changes in energy and momentum through interactions.
No, the interaction between two massless particles cannot be observed directly as they do not have a physical presence. However, the effects of their interactions can be observed through indirect measurements and experimental techniques.
