According to quantum field theory, the universe can be thought of not as isolated particles but continuous fluctuating fields: matter fields, whose quanta are fermions (i.e., leptons and quarks), and force fields, whose quanta are bosons (e.g., photons and gluons). All these fields have zero-point energy.>

Zero-point Energy

Is the quantum mechanical math just easier to calculate each having its own separate field, rather than an identical field of origin, but each unique excitation giving each their own identity/unique properties?

Sometimes QM systems seem true to reality and at other times just the best description we have at the moment - I find it more plausible for there to be a shared field of origin that diverges from unique excitations/properties. It’s also very likely I’m studying QM fields incorrectly.

Thanks for any insight.
