Interactions are not properties, but events
When the bridge comes into operation, a deep consequence emerges, often underestimated: interactions cease to be attributes of particles. In usual language it is said that a particle has a charge, has a certain interaction with the outside world, undergoes a force, but if the exchange is mediated by a "bridge", this way of speaking becomes misleading. No interaction exists alone An interaction does not exist as an isolated intrinsic property of a particle. For there to be an interaction it is necessary that there is a system of two particles that exchange something that we call mediator. The "bridge" is the connection system between the two particles and considering that the elementary particles in nature all have an electric charge, the original nature of the bridge is electromagnetic. The bridge is not a static system but a system of two particles in electromagnetic interaction during their motion in the universe and when the bridge is realised, a pred...
