Most people, even if they're skeptical, have had some experience of metaphysics - whether it's something to do with dimensions or spirits, the experience goes into the 'spooky' category, where Einstein put non-locality.
Quarks - or more specifically, quark matter - make/s up around 27% of our mass. [Thanks to Vladimir Kekelidze at SQM19 for that piece of invaluable information.] Quarks have the strange ability to oscillate (from one version of themselves, known as a 'flavour', to another), sharing this ability only with (as far as we know) the neutrino. So what if this quark matter is the material on which our cellular and soulular bodies hinge together? There's pretty good ground for this theory, if you take the breadth of probabilities into account.
Oscillation takes place at speeds we don't know about, while scientists are still arguing over the speed-of-light problem (whether it can be exceeded, thus violating general relativity, or whether quantum processes naturally bypass the problem by ignoring time altogether). Where two particles are involved in the process, there arises the issue of non-separability, argued between Einstein and Schroedinger and expanded upon usefully here.
In searching for the substance of the soul, or the energy signature which survives death, we could be looking for that part of quark-gluon plasma that exists simultaneously within this dimension (the one our 5 senses perceive) and in other dimensions (including whichever dimension our energy goes to after we die). When we wear our clothes, they become part of us. Walking around with clothes on feels so natural that it could be said the quark matter of our clothes and that of our bodies becomes entangled, which is not difficult to imagine being the case, and if (as is usually so) we die with clothes on, it would make sense, perhaps, that clothes and body share whatever separation takes place between this realm and the next.
More than likely, you've pondered the life-after-death scenario as I have, and concluded that there must be something in it, as Dr Lanza would have us believe. I believe some time ago he said something about microtubules.....
