But the process is directed by the dependability of the data used to form concepts of what is being observed. The consistency of the spacetime actions/reactions is what begs one to believe they should limit conceptualizations to just that which can be measured and contained in actions/reactions carried out in the limited realm of our physical aspects. That the conceptualization occurs outside of that realm is dismissed too easily by some scientists.
Scripture telling the story of Jesus' earthly sojourn indicate that an alternate or other physicality may in fact exist to which we have yet to reach and make measurements. To arbitrarily dismiss that realm is perhaps comfortable for some scientists, but it is not a useful self-limitation given the advances we've made in measuring ... we may be in fact able now to start making measurements of this 'other realm' of physicality, so dismissing the possibility of its existence is, well, silly.
Quantum Physics has pointed to the existence of space and time variables which we ought to be exploring if we can figure out ways to do so. And some scientists are actually anticipating such exploration, while other scientists wish to dismiss the possibilities out of hand.
The explanation Cajun gave above is a prime example of speaking about different variability realms of space and time. What Cajun wrote was certainly not gibberish, and the description begged consideration of states of reality not yet accessible directly but which can be explored via 'shadows', as the other realm's effects upon our realm. That is almost Platonic to consider 'shadows' as means to explore other realms, don'tcha think?
WHat if ideas originate NOT in the brain but in the spirit.. and the human brain is mechanical like a "telephone".. and just transduces ideas relaying them.. from the spiritual dimension/realm to the fleshly/material realm/ one..
Well, come to think of it I might elaborate on Plato just a tad further. He didn't believe in "shadows" per se; he believed in forms of divine provenance....
