The Problem of Time & the TGD Counterpart of F = ma

Abstract

An innocent looking question "What $F=ma$ means in TGD?", posed by Lawrence B. Crowell in a FB discussion, can be abstracted to the question how the transfers of conserved isometry charges of H=M4 x CP2 are realized at the level of fundamental interactions. At this level, the question is about how the conserved charges associated with the initial state particles are redistributed between the final state particles. Somewhat surprisingly, TGD based quantum ontology implies that quantum non-determinism is an essential part of the answer to the question. Equally surprisingly, also a connection with the theory of consciousness and cognition emerges at the fundamental elementary particle level. In the TGD view, the weak violation of the classical non-determinism in holography = holomorphy vision of TGD leads to the identification of self as a sequence of "small" state function reductions (SSFRs) identified as TGD counterparts of repeated measurements of the same observables: now however the observables related to the non-determinism are measured in SSFRs and give rise to the correlates of cognition. By quantum criticality, a "big" state function reduction (BSFR) as the TGD counterpart of what occurs in quantum measurement, can take place. BSFR means the death of self and its reincarnation with an opposite arrow of time. Quantum criticality of the TGD Universe, realized in terms of holography = holomorphy principle, would be essential for this. For instance, particle decay involving topological changes could correspond to this process and all particle interactions would basically be due to the quantum criticality so that instead of SSFR, BSFR takes place. Intention is transformed to action at fundamental level. Cognition is dangerous in the TGD Universe!

Retrocausality & TGD

Matti Pitkänen

This article is inspired by the article "Is a time symmetric interpretation of quantum theory possible without retrocausality?" of Leifer and Pusey related to the notion of retrocausality. Retrocausality means the possibility of causal influences propagating in non-standard time direction. The conjecture is that retrocausality could allow wave functions to be real and allow to get rid of the problematic notion of state function reduction. TGD leads to a new view about reality of wave function solving the basic problem of quantum measurement theory. In ZEO quantum states are replaced by zero energy states analogous to pairs of initial and final states in ordinary positive energy ontology and can be regarded as superpositions of classical deterministic time evolutions. The sequence of state function reductions means a sequence of re-creations of the superpositions of classical realities identified as space-time surfaces. The TGD based view about scattering amplitudes has rather concrete connection with the view of Cramer as I interpret it. There is however no attempt to reduce quantum theory to a purely classical theory. The notion of the "world of classical worlds" (WCW) consisting of classical realities identified as space-time surfaces replaces space-time as a fixed observer independent reality in TGD. Retrocausality is basic aspect of TGD. Zero Energy Ontology (ZEO) predicts that both arrows of time are possible. In this sense TGD is time symmetric. On the other hand, twistor lift of TGD predicts a violation of time reflection T and this might imply that second arrow of causality dominates in some sense. The ZEO based view about state function reduction essential for TGD inspired theory of consciousness and implying generalized Zeno effect giving rise to conscious entities - "selves" - is also essential. One might say that when conscious entity dies it re-incarnates as time-reversed self.

Topological Geometro Dynamics Inspired Theory of Consciousness

Matti Pitkänen

TGD inspired theory of consciousness relies on two fundamental identifications. The identification of quantum jump between quantum histories as a moment of consciousness reduces quantum measurement theory to fundamental physics and solves long list of paradoxes of modern physics. The identification of self as a subsystem able to remain unentangled in subsequent quantum jumps provides a quantum theory of observer and one can identify self also as a fundamental statistical ensemble. The generalization of spacetime concept so that it allows both real and p-adic regions, is a crucial prequisite for the notion of self. Quantum jump between quantum histories decomposes into three parts corresponding to the unitary U process of Penrose followed by the TGD counterpart of state function reduction in turn followed by a cascade of self-measurements giving rise to the TGD counterpart of state preparation. The dynamics of self-measurement is determined by the so-called Negentropy Maximization Principle (NMP). Selves form a hierarchy and self experiences its subselves as mental images and is in turn a mental image of a higher-level self. Selves can have common subselves and this makes possible fusion and sharing of mental images. The experience of self is a statistical average over quantum jumps occurred after the last 'wake-up' and the theory of qualia can be formulated in terms of statistical physics. Self experiences the subselves of subself as a statistical average so that self-hierarchy means also an abstraction hierarchy. Self has as its geometric correlate so called mindlike spacetime sheets of finite duration with respect to the geometric time (as opposed to subjective time determined by the sequence of quantum jumps) and one can understand how psychological time and its arrow emerge. The paradigm of four-dimensional brain provides a completely new view about long-term memories and intentionality. Crucial element behind all these developments are both the classical non-determinism of the fundamental variational principle determining the dynamics of the spacetime surfaces making possible nondeterminism of symbolic representations and the inherent nondeterminism of p-adic differential equations making possible cognitive representations. Together with the nondeterminism of quantum jump these nondeterminisms make possible the self-referentiality of consciousness. Combining this general theory with the notion of manysheeted spacetime one ends up to a vision about biosystems as macroscopic quantum systems and to a rather detailed view about quantum brain.

About the Nature of Time

Matti Pitkänen

The identification of the experienced time te and geometric time tg involves well-known problems. Physicist is troubled by the reversibility of tg contra irreversibility of te, by the conflict between determinism of Schrödinger equation and the non-determinism of state function reduction, and by the poorly understood the origin of the arrow of tg. In biology the second law of thermodynamics might be violated in its standard form for short time intervals. Neuroscientist knows that the moment of sensory experience has a finite duration, does not understand what memories really are, and is bothered by the Libet's puzzling finding that neural activity seems to precede conscious decision. These problems are discussed in the framework of Topological Geometrodynamics (TGD) and TGD inspired theory of consciousness constructed as a generalization of quantum measurement theory. In TGD space-times are regarded as 4-dimensional surfaces of 8-dimensional space-time H=M4×CP2 and obey classical field equations. The basic notions of consciousness theory are quantum jump and self. Subjective time is identified as a sequence of quantum jumps. Self has as a geometric correlate a fixed volume of H- "causal diamond"-defining the perceptive field of self. Quantum states are regarded as quantum superpositions of space-time surfaces of H and by quantum classical correspondence assumed to shift towards the geometric past of H quantum jump by quantum jump. This creates the illusion that perceiver moves to the direction of the geometric future. Self is curious about the geometric future and induces the shift bringing it to its perceptive field. Macroscopic quantum coherence and the identification of space-times as surfaces in H play a crucial role in this picture allowing to understand also other problematic aspects in the relationship between experienced and geometric time.

Matter, Mind and the quantum

Matti Pitkänen

Topological Geometro-Dynamics (TGD) is a unified theory of fundamental interactions. TGD involves a quite far-reaching generalization of the space–time concept and, apart from the notion of quantum jump, reduces quantum theory to infinite-dimensional geometry. General coordinate invariance forces the identification of the quantum states as quantum histories rather than time-constant snapshots of a single quantum history: this solves the basic determinism/non-determinism paradox of quantum measurement theory. The identification of the quantum jump as a moment of consciousness defines the microscopic theory of consciousness. p-Adic numbers is one of the basic new mathematical concepts necessary for the formulation of quantum TGD. The notion of the self as a subsystem remaining p-adically unentangled under the action of the “time evolution” operator U (S-matrix) associated with the sequential quantum jumps Ψ i UΨ i Ψ f is central for the macroscopic theory of consciousness. Vanishing p-adic entanglement means subcritical real entanglement so that the self can be regarded as a critical phenomenon. The moments of consciousness which occurred after the last “wake-up” bind temporally to a single experience and give rise to immediate subjective memory. Each self represents a self-organizing system approaching a stable self-organization pattern selected by dissipation. A self can have sub-selves and experiences sub-selves as mental images which are averages about mental images of sub-sub-selves. An infinite hierarchy of selves giving rise to an abstraction hierarchy is predicted. The notion of the manysheeted spacetime and the classical non-determinism of the Kähler action defining configuration space geometry are crucial for understanding how psychological time and cognition emerge in the TGD-universe and a rather radical generalization of the views about the relationship of subjective and geometric time is forced.
