what is the differace between a particle and a virtual particle?
Trip2 said:so virtual particles are retrocausal?
A virtual particle is a quantum phenomenon that does not have a physical existence but can briefly appear as a fluctuation in a vacuum. It is a manifestation of the uncertainty principle in quantum mechanics.
Virtual particles differ from regular particles in that they do not have a definite mass, energy, or momentum. They also do not obey the laws of conservation of energy and momentum, and they only exist for a very short amount of time before disappearing again.
No, virtual particles cannot be observed or detected directly. They do not leave any trace or impact on the physical world, and their existence can only be inferred through their effects on other particles.
Virtual particles play a crucial role in many phenomena, such as the Casimir effect, Hawking radiation, and the Lamb shift. They also provide a way to understand and calculate interactions between particles in quantum field theory.
Virtual particles are a mathematical concept used to explain and calculate quantum phenomena. They do not have a physical existence, but their effects can be observed and measured in experiments. Therefore, they can be considered as real in the context of quantum mechanics.
