This illustrates an aspect about the maths of quantum mechanics: one normally doesn't include the measuring device into the description of a quantum mechanical system being measured. In the case of quantum decoherence, the irreversible nature of wavefunction collapse is the result of not including the measuring device in the description, while including the measuring device leads to unitary evolution of the total system wavefunction.

This effectively mirrors my logic in constructing this thread. This and other aspects force me to consider the nature of physical measurement as essentially spatially oriented, where measurement of time related components are examined and interpreted in a spatial context, not within it's own context. Though a thorough examination may possibly still provide a plausible Panspermia mechanism, the focus of this thread would appear to mostly concern the nature of time and the relevance of it's interpretation within measurement. Thanks for the feedback KJW.
