which, if sufficiently small, may not affect the correct re-assembly of the entire body macrostructure. But it is unlikely that considerations of this kind would be able to significantly change the infinitesimality of ${\cal P}_{\rm body}$.

Cooling down the body
=====================

At this point some readers may rightly object that we don’t really needed our “disassembling sci-fi hypothesis,” as what generally makes a macroscopic object like our human body behave classically, i.e., spatially and locally, is just the fact that it is immersed in a thermal environment, i.e., that it is constantly subjected to the random collisions of countless microscopic entities, in particular photons, and that the overall effect of these innumerable interactions is that of producing its continuous “collapse into space,” which would be essentially the reason why it would behave differently from a “pure” quantum entity, like an electron. To use once more our metaphor, this bombardment is what would force the body to remain inside the water of the pool, preventing its owner from becoming a diver.

So, one could object that, to allow the body to quit the “spatial pool,” and temporarily become a non-spatial entity, it would be sufficient to shield it from the external
