Conserved but Not Continued: Decoherence, Information, and the Finality of the Conscious Subject (Part II)

The first part of this study argued that a human self is best understood as an organised information pattern, that the Hard Problem of consciousness leaves the fate of subjective experience at death formally undecided, and that epistemic agnosticism is the honest response. This second part examines that gesture in detail through quantum mechanics—unitarity, many worlds, decoherence, and quantum biology—arguing four main propositions: observer neutrality, a strict timescale constraint in neural tissue, the distinction between fine-grained information conservation and pattern continuation ("conserved but not continued"), and the failure of quantum immortality as a survival guarantee. Physics closes the quantum doors to survival, leaving the metaphysical question open.
