Is spirit an interconnected, infinite web of subatomic particles of which everything (or atleast a lot of stuff) is made?
Not sure if this is what you mean,...if one views the subatomic particles are matter, then spirit is the invisible and undetectable space/vacuum that fills all space in which particles have their existence.
That quantum vacuum is not really a vacuum for it is comprised of cosmic energy known as Zero Point Energy (ZPE) which is omnipresent though out the Universe,
Now different theories use different names for this universal field, in religions it is Spirit, in metaphysics it is Aether, for some scientific researchers it is the Zero Point Field, and for contemporary particle physics it is the Higgs Field (The Higgs field is theorized as being invisible and undetectable by contemporary science, and existing through the whole universe)
Now my personal understanding is that matter particles are spherical 'standing' waves of cosmic energy/spirit which take their place, matrix like (according to those points in space where it so happens that there is an equal balance of incoming energy and outgoing energy), in the universal 'ocean' in which all exists. So 'God' is immanent in all things and simultaneously transcendent to all things. Nothing can be ever added to the universe nor can anything ever be taken out of it for there is no other place in existence to add to or take from....
