Is that to say that to maintain it's existence as a discrete energy packet it needs to move (at speed relative to the our ref. frame), else the energy is...,what, re-absorbed into the quantum foam or is employed otherwise as part of another quantum construct, or some such???
(forgive the lack of conceptual terminology please, but perhaps u understand the gist of the question)
