I will try to find some time to take a look.But personally I think that many-worlds is already a consequence ofmechanism, well before quantum mechanism. In that sense I thinkthat quantum mechanism (in physics) confirms digital mechanism (intheology).BrunoI'd think you'd be very happy with this paper - which comports withan infinite "everything".Born in an Infinite Universe: a Cosmological Interpretation ofQuantum MechanicsAuthors: Anthony Aguirre, Max Tegmark, David Layzer (Submitted on 5 Aug 2010)Abstract: We study the quantum measurement problem in the context ofan infinite, statistically uniform space, as could be generated byeternal inflation. It has recently been argued that when identicalcopies of a quantum measurement system exist, the standardprojection operators and Born rule method for calculatingprobabilities must be supplemented by estimates of relativefrequencies of observers. We argue that an infinite space actuallyrenders the Born rule redundant, by physically realizing alloutcomes of a quantum measurement in different regions, withrelative frequencies given by the square of the wave functionamplitudes. Our formal argument hinges on properties of what we termthe quantum confusion operator, which projects onto the Hilbertsubspace where the Born rule fails, and we comment on its relationto the oft-discussed quantum frequency operator. This analysisunifies the classical and quantum levels of parallel universes thathave been discussed in the literature, and has implications forseveral issues in quantum measurement theory. It also shows how,even for a single measurement, probabilities may be interpreted asrelative frequencies in unitary (Everettian) quantum mechanics. Wealso argue that after discarding a zero-norm part of thewavefunction, the remainder consists of a superposition ofindistinguishable terms, so that arguably "collapse" of thewavefunction is irrelevant, and the "many worlds" of Everett'sinterpretation are unified into one. Finally, the analysis suggestsa "cosmological interpretation" of quantum theory in which the wavefunction describes the actual spatial collection of identicalquantum systems, and quantum uncertainty is attributable to theobserver's inability to self-locate in this collection.Comments: 17 pages, 2 figuresSubjects: Quantum Physics (quant-ph); Cosmology and ExtragalacticAstrophysics (astro-ph.CO); General Relativity and Quantum Cosmology(gr-qc); High Energy Physics - Theory (hep-th)Cite as: arXiv:1008.1066v1 [quant-ph] BrentOn 29 Aug 2010, at 00:59, ronaldheld wrote:http://arxiv.org/PS_cache/arxiv/pdf/0905/0905.0624v2.pdf Any comments on this large apper?
