Pixels themselves are artifacts. The spaces between elementary particles are vast. I guess you mentioned newer physics to talk about things like superstring.
It's not "my" meditative practice, and my experience isn't a thing, either. Those are abstract constructs.
You're welcomed to explore "fulness". Lots of people are. Until you experience it for yourself, though, you won't really understand. This isn't something that you can pawn off onto an observational instrument. You ... hmm, what was that post-modern jargon? You disintermediate yourself as the observer and the observed.
The "fulness", by the way, is not new either. The "no self" teaching is the same as "true self" teaching -- your "fulness" that you treat semantically. That is, that there is a fundamental "Nothing" that is at the same time, all-inclusive Everything.
Anyways, I've discussed this as far as I want to. I encourage you to empirically observe this yourself. Not discuss it, not study it, not debate it, not reply to it: empiricism in its original sense of finding out for yourself, and experiencing it for yourself. If you sincerely want to explore the relevance of this age-old practice, you cannot do this second hand. (There are other methods besides meditation; you can check out Rick Strassman's book for other methods; the meditative states trigger the same kinds of neural chemical reactions, albiet for the rare ~2% of the population that get it spontaneously, or spent a lot of time with it).
