The standard model has 17 named fundamental particles and each of these particles are derived from a corresponding field. Do you visualize these fields as additions to the properties of the vacuum or part of a single quantum vacuum? For example, virtual electron/positron pairs are continuously forming and annihilating. Are the virtual electrons/positrons distinct additions to the vacuum or is the electron/positron field and these virtual particles a fundamental part of the quantum vacuum?
If an expanded model of the quantum vacuum incorporates all fields, this implies that a grand unification of all particles and forces is possible. However, if all these fields are independent, then unification does not appear to be possible.
