Introduction
My work is the result of an operational analysis of the hard problems of quantum theory using logical type.

This explains the origin of the dualism of fundamental dynamics in quantum mechanics. The relevant distinction is not scale, micro or macro, but the type of physical frame of reference. They are domains of different logical types in the unitary system, Everett's absolute and relative states. The evidence is the holographic universe, the cosmology o...

The thought experiment of Wigner's friend (1961) illustrates that physical reality is different for different observers of the same world. This is now confirmed experimentally by Proietti et al. (2019). This counter-intuitive feature of quantum mechanics is greatly simplified in the many-minds perspective of Everett's (1957) formulation when taken...

The entity at the heart of Everett's (1957) formulation of quantum mechanics is the state of the memory, defined as the record of observations. He makes clear that this is the sole protagonist of the collapse dynamics. This resolves the problems of quantum theory by demonstrating an ontological dualism: the different types of frame of reference, ob...

In Part 1 the solution to the measurement problem is shown to be logical type. The world encountered is a class-of-worlds-as-a-world, a domain in which the collapse dynamics operates in a clearly defined ontology. A further level of logical type resolves the paradoxes of special relativity, and reveals the full definition of transtemporal reality....

As shown in Part 1, the physical reality encountered and on which quantum physics experiments are performed is the superposition of a whole class of decoherent quasi-classical worlds, a second-logical-type phenomenon, hence the paradoxical results. This is the physical reality of the protagonist defined by Everett (1957): the record of observations...

Psi-epistemic interpretations of quantum mechanics, such as Quantum Bayesianism and the many-minds theories, are criticised for their anthropocentric nature as well as the lack of ontology. If the well-established physics of Everett's formulation is taken at face value, the paradoxes are resolved just as these theories suggest, and an inherent phys...
Article

The nature and topology of time remain an open question in philosophy. Both tensed and tenseless concepts of time appear to have merit. Quantum mechanics demonstrates that both are instantiated, as complementary aspects of the time evolution of physical systems. The linear dynamics is tenseless. It defines the universe probabilistically throughout...
Article
Full-text available
A perspective on Everett's relative state formulation is proposed, leading to a simple relational quantum mechanics. There are inevitably a large number of different versions of the world in which a specific observer could exist, and in the universe of the total unitary wave function they are all existing and superposed. If these different versions...
Article
Full-text available
Everett demonstrates the appearance of collapse, within the context of the unitary linear dynamics. However, he does not state clearly how observers are to have determinate measurement records, hence 50 years of debate. This, however, is inherent. He defines the observer as the record of observations, which, naturally, is the record of correlations...
Article
Full-text available
As shown in The Quantum Mechanical Frame of Reference, Everett's formulation inherently defines idiosyncratic effective physical environments for each version of the functional identity of the observer, defined solely by observations, in the manner of Rovelli's Relational Quantum Mechanics. This accounts for determinate measurement records, and com...

Barbour shows that time does not exist in the physical world, and similar conclusions are reached by others such as Deutsch, Davies and Woodward. Every possible configuration of a physical environment simply exists in the universe. The system is objectively static. Observation, however, is an inherently transtemporal phenomenon, involving actual or...
Article
Objectively, time does not pass, physics reveals no such phenomenon. While subjectively we find ourselves at a specific point in time, 'now', and we appear to pass from moment to moment, physics can accommodate neither of these concepts, thus there is no explanation of subjective transtemporal reality, or how an observation could possibly be made....

Mitra demonstrates that specific memory erasure causes the observer to be in a different sector of the multiverse, one with a different destiny: events in the future, remote to any possible influence of the observer, having radically different probabilities. The concept only applies to an observer defined by a structure of information, so cannot ap...
Article
Full-text available
The nature and topology of time remains an open question in philosophy, both tensed and tenseless concepts of time appear to have merit. A concept of time including both kinds of time evolution of physical systems in quantum mechanics subsumes the properties of both notions. The linear dynamics defines the universe probabilistically throughout spac...

A perspective on Everett's relative state formulation is proposed leading to a relational quantum mechanics. There are inevitably a large number of different versions of the universe in which a specific observer could exist, and in the universe of the unitary wave function they are all existing and coincident. If these different versions of the uni...
