Quantum-Geometry Dynamics: A Deterministic View of Measurement

Quantum-Geometry Dynamics; an axiomatic approach to physics does not explicitly dedicate a section solely to the "measurement problem" as it is known in quantum mechanics. However, QGD's fundamental principles and its critique of quantum mechanics offer a perspective that implicitly addresses the issues at the heart of this problem.

Here's how QGD approaches the challenges raised by the measurement problem:

• Strict Causality and Determinism: QGD is founded on the principle of strict causality, which asserts that every successive state of a particle, structure, or system is strictly and uniquely causally linked to the preceding one. This deterministic view stands in contrast to the standard interpretation of quantum mechanics where measurement outcomes are probabilistic. From a QGD perspective, the apparent randomness of quantum measurements is likely not fundamental but rather a consequence of an incomplete description at the quantum level.

• Discrete Nature of Reality: QGD posits that space and matter are fundamentally discrete. This discreteness implies that the evolution of systems occurs through discrete steps governed by strict causal laws at the level of preons. What appears as a probabilistic "collapse" of a superposition upon measurement in quantum mechanics might be explained in QGD as a deterministic transition between discrete states that is currently not fully understood or accessible by continuous mathematical models.

• Rejection of the Uncertainty Principle as Fundamental: QGD considers the uncertainty principle a consequence of quantum mechanics' assumption of continuous space, rather than a fundamental limitation of reality itself. In a discrete and strictly causal framework, the simultaneous and certain measurement of conjugate properties should, in principle, be possible. This suggests that the limitations imposed by the uncertainty principle in quantum mechanics, which contribute to the puzzle of measurement, are not inherent in the underlying reality as described by QGD.

• Instantaneous Gravitational Interactions: QGD proposes that gravitational interactions are instantaneous. This non-local aspect of QGD could be relevant to how measurement on one part of a system seemingly instantaneously affects another, as seen in entanglement. QGD suggests that observed violations of Bell's inequalities might be due to these instantaneous classical (gravitational) effects rather than quantum non-locality. This could imply that the act of measurement involves instantaneous gravitational interactions that determine the outcome in a strictly causal way.

• Incompleteness of Quantum Mechanics: QGD implicitly suggests that quantum mechanics is an incomplete theory. The need for probabilistic interpretations and the difficulties associated with the measurement problem might indicate that quantum mechanics does not fully capture the underlying deterministic and discrete reality. QGD aims to provide a more fundamental axiomatic basis that can explain these phenomena through strictly causal mechanisms at the preonic level, potentially resolving the measurement problem by providing a deterministic account of what happens during a measurement.

In summary, while QGD does not offer a specific "solution" to the measurement problem as a distinct topic, its core tenets of strict causality, the discrete nature of reality, the view of the uncertainty principle as non-fundamental, and instantaneous gravitational interactions provide a framework that inherently challenges the probabilistic interpretation of quantum measurement. QGD would likely argue that what appears as the "collapse" of a wave function is a deterministic process governed by underlying causal laws at the preonic level, and that a more complete theory based on its axioms would ultimately provide a strictly causal explanation for measurement outcomes.

Preonic Waves: An Alternative to Gravitational Waves

 

"Quantum-Geometry Dynamics (anaxiomatic approach to physics)" presents a theory (QGD) that has a distinct perspective on gravity and related phenomena, including what might be interpreted as gravitational waves. 

• QGD Precludes Gravitational Waves: According to QGD, gravitational waves do not exist. Instead, the signals detected by the LIGO-Virgo observatories, which are consistent with the gravitational waves predicted by general relativity, are proposed to have a different nature. 

•Preonic Waves as an Alternative: QGD suggests that the signals detected by LIGO-Virgo could be composed of polarized preons (the fundamental quanta of space in QGD) resulting from the polarization of large regions of the preonic field by coalescing binary systems, or by dark photons. The mechanism of preonic field polarization is discussed in the context of electromagnetic effects in QGD. 

•Polarization Mechanism: In QGD, polarizing particles or structures (analogous to charged particles in standard physics) interact with the preonic field (composed of free preons), causing it to become polarized. The intensity of this polarization, or magnetic moment, is proportional to the angular spin momentum of the particle and the density of the preonic field. For a binary system, as the stars accelerate towards each other, they become increasingly polarizing, leading to a wave-like variation in the polarization of the neighboring preonic field. 

•Distinguishing Preonic Waves from Gravitational Waves: QGD proposes that preonic waves could impart momentum to the mirrors of the LIGO-Virgo detectors, similar to how magnetic fields interact with matter. The variations in frequency and magnitude of these preonic waves, resulting from the dynamics of the coalescing bodies, would be similar to those predicted for gravitational waves by general relativity, making them observationally difficult to distinguish. QGD suggests that new experiments and instruments might be needed to differentiate between these two interpretations. 

•QGD Cosmogony and the Preonic Universe: QGD's cosmological model starts with an initial state where only free preons (+) existed and were homogeneously distributed throughout quantum-geometrical space. This is termed the preonic universe [16]. In this initial phase, the n-gravity (repulsive force between space preons (-)) and p-gravity (attractive force between matter preons (+)) fields were in perfect equilibrium. Over time, due to p-gravity, preons (+) condensed to form particles, starting with neutrinos and then photons, which eventually formed the cosmic microwave background radiation (CMBR). The observed isotropy of the CMBR is a consequence of the initial isotropic distribution of preons (+). 

•Dark Matter and Dark Energy in QGD: QGD attributes the effects of dark matter to interactions between light and material structures with regions of space where free preons (+) have condensed (dark matter halos) [19-21]. The dark energy effect is suggested to be related to the jets of preons (+) and neutrinos radiated from black holes. 

•Implications for Cosmology: The QGD perspective alters the understanding of cosmological phenomena like redshift. QGD predicts an intrinsic gravitational redshift at the source itself, caused by gravitational acceleration, which contributes to the observed cosmological redshift, along with the Doppler effect. This explanation does not require the expansion of space in the same way as some interpretations of general relativity. Repulsive gravity at cosmological scales (between structures separated by distances greater than a threshold dΛ) also contributes to the large-scale structure and recession speeds of galaxies.

In contrast, the "New DESI Results Strengthen Hints That Dark Energy May Evolve" article focuses on observations within the standard cosmological model. It discusses how the Dark Energy Spectroscopic Instrument (DESI) data, combined with other cosmological observations, suggests that dark energy's influence might change over time, which poses a challenge to the standard model of cosmology. This article does not directly address gravitational waves or preonic fields. 

In summary, the QGD framework, as presented in one of the sources, offers an alternative explanation for the phenomena attributed to gravitational waves, suggesting they might be preonic waves arising from the polarization of the preonic field. This concept is embedded within a broader cosmological model that posits a preonic universe as its origin and offers alternative interpretations for dark matter, dark energy, and cosmological redshift, differing significantly from the standard cosmological model discussed in another source.

 

Strict Causality in Quantum-Geometry Dynamics: Implications for Physics

 The concept of a strictly causal universe as defined by Quantum-Geometry Dynamics (QGD) has significant implications for physics theories. According to QGD, all successive states of a particle, structure, or system are strictly and uniquely causally linked. This principle offers a way to understand the evolution of the universe as sequences of events connected by cause and effect, potentially allowing a description of evolution without relying on the relational concept of time.

Here are some key implications of a strictly causal universe within the framework of QGD for physics theories:

• Challenge to Spontaneity: Strict causality in QGD excludes spontaneity, which assumes that a particle or system can change based on probability over time without a specific cause. This challenges interpretations in other theories that might rely on inherent probabilistic behaviors without a clear causal mechanism at the fundamental level.
• Understanding the Source of Incompatibilities: QGD proposes that if reality is strictly causal, then it can be thought of as a complete and consistent axiomatic system. In this view, fundamental aspects of reality correspond to axioms, and non-fundamental aspects (observable phenomena) correspond to theorems. Incompatibilities between current physics theories arise because they are often founded on theorems derived from observations at different scales, rather than a unified set of fundamental axioms. A strictly causal framework suggests that a unified theory would require identifying the true fundamental axioms of reality.
• Possibility and Nature of a Theory of Everything (TOE): QGD's strict causality implies that a TOE is possible if it can be derived from the complete and consistent set of fundamental axioms governing the universe. However, it also suggests that achieving a TOE by simply unifying existing theories like the Standard Model and General Relativity might be mathematically impossible because they are based on mutually exclusive axiom sets. Instead, a TOE would need to be derived axiomatically from the most fundamental aspects of reality.
• Alternative to Time as a Fundamental Concept: The principle of strict causality in QGD suggests that the evolution of any system can be described without necessarily resorting to the relational concept of time. The universe changes from one state to the next due to concurrent causally related series of events, rather than evolving with time. This could lead to different formulations of physical laws that prioritize causal sequences over temporal evolution.
• Implications for Measurement and Observation: In a strictly causal universe as described by QGD, any change in a system is due to a specific cause. This perspective could influence the interpretation of quantum measurements and the role of the observer. While QGD acknowledges non-local effects, it attributes them to instantaneous gravitational interactions rather than inherent quantum randomness, suggesting a causal link even across distances. This contrasts with interpretations of quantum mechanics that emphasize intrinsic indeterminacy.
• Foundation for Axiomatic Approaches: QGD itself is presented as an axiomatic approach to physics, where the principle of strict causality is a guiding principle in choosing the fundamental axioms (such as the discreteness of space and the existence of preons). A strictly causal universe reinforces the idea that physics theories should be built from a self-consistent set of axioms that correspond to fundamental aspects of reality.

In summary, a strictly causal universe as envisioned by QGD has profound implications for how we understand the fundamental nature of reality, the relationships between different physics theories, and the possibility of a unified description of the universe. It emphasizes the primacy of causal connections and challenges the fundamental status of concepts like continuous space and time as they are often understood in other frameworks.
