Science proving the afterlife?

A physiological phenomenon is phantom during a clealy real biological measurement of weight loss of a human being's body changing from 'alive' to 'expired', researchers of an affiliation not hard to find have scientifically confirmed and reconfirmed. It does not seem to be readily perceivable what, how, where, or who about that weight, and no chemical changes are understood at that moment that are attributed characteristic of or occur abject to it, and no material( whether solid, liquid, or gas) can be identiied as leaving, yet the loss of a fewer than a few ounce least double digit gram mass differing is measured accurately and precisely. The medical caregiver/researchers concluded evidence of a normal and regularly unidentifiable motion of mass,( but i.d.'d neither mass nor motion). There was nothing constant about any other experiences gained in observing the solemn passing of a human life than what has been repeatedly studied and reported previously, with sacred regard, and is hereby referenced here with a like congruence.
