Let’s use the spotlight analogy, but notice how it is neither A Theory nor B Theory, but a hybrid/synthesis (C Theory).
The HereNow is like a spotlight (observer) in spacetime. Every freezeframe, the spotlight-subject-to-spacetime is in a different part of spacetime, unable to experience all of space, or all of time. How much of space and time the spotlight can access depends on things like the reach of their senses.
In the The Harmonic Triads thread, the spotlight (herenow) is blue, time is red, and space is yellow.
Only an omnitemporal (all red), omnispatial (all yellow) being’s spotlight experiences every herenow (blue) without limit (without being “subject to” spacetime)—immediately, immanently, omnipresently—synthetic a priori incarnate.
