  At the primary level of reality as described by quantum field theory, a
fundamental particle like an electron represents a stable, discrete,
propagating excited state of its underlying quantum field. QFT also tells us
that the lowest vacuum state as well as the excited states of such a field is
always very active with spontaneous, unpredictable quantum fluctuations. Also
an underlying quantum field is known to be indestructible and immutable
possessing the same value in each element of spacetime comprising the universe.
These characteristics of the primary quantum fields together with the fact that
the quantum fluctuations can be cogently substantiated to be quantum coherent
throughout the universe provide a possible ontology of the quantum theory. In
this picture, the wave function of a quantum particle represents the reality of
the inherent quantum fluctuations at the core of the universe and endows the
particle its counter intuitive quantum behavior.
