Key research themes

1. How does the structure and evolution of spacetime and cosmology underpin the arrow of time?

This theme investigates how fundamental cosmological models and spacetime properties establish or influence the arrow of time, focusing on mechanisms that generate or reset irreversibility and time directionality across cosmic scales. It examines the emergence of time asymmetry from geometric, thermodynamic, and quantum gravitational perspectives, including the interplay between entropy, conformal cycles, and gravitational complexity. Understanding this is crucial for reconciling the macroscopic arrow of time with microscopic symmetric laws and advancing cosmology's explanatory power over time's unidirectional flow.

Key finding: Defines the cosmological arrow of time independently from entropy by leveraging geometric properties of spacetime, arguing that standard cosmological models satisfy conditions allowing a universal, geometric time direction;... Read more
Key finding: Introduces the concept of vertical time organizing universes in a meta-temporal axis, uniting Penrose's Conformal Cyclic Cosmology (CCC) and Smolin's cosmological natural selection, whereby cyclic aeons reset entropy and... Read more
Key finding: Provides a rigorous, evidence-based analysis of vertical time frameworks, particularly CCC, elucidating how entropy and the thermodynamic arrow reset between successive universes and offering philosophical insight into the... Read more

2. Can discrete spacetime models and network-based quantum thermodynamics explain the emergence and mechanisms of the arrow of time and time dilation?

This theme focuses on the role of discrete spacetime quantum networks composed of Space Elementary Quanta (SEQ) whose state transitions underpin time as a discrete, entropy-driven phenomenon. It explores how entropy accumulation, spatial compression via gauge symmetries like SU(3), and network excitations contribute to emergent gravitational fields, mass, and observed relativistic effects such as time dilation. This sheds light on integrating thermodynamics, quantum mechanics, and relativity within a unified, discrete framework and offers falsifiable predictions regarding fundamental particle asymmetries.

Key finding: Proposes a discrete spacetime model where time arises as entropy-increasing steps in the SEQ network; local space compression mediated by SU(3) symmetry induces gravitational fields, with mass as stored gravitational... Read more
Key finding: Develops a quantum thermodynamics framework where time emerges from discrete state transitions in the SEQ network, linking entropy increase directly to the arrow of time at Planck scale; explains special relativity phenomena... Read more
Key finding: Extends the discrete SEQ network model proposing that SU(3) gauge symmetry compresses local SEQ structure storing elastic potential energy as mass while inducing spatial stretching as gravity; the Higgs field functions as a... Read more
Key finding: Builds a comprehensive discrete model connecting quantum spacetime network dynamics with macroscopic time concepts, rigorously linking global and local time via space transformations; offers a physical mechanism for... Read more

3. What are the philosophical, phenomenological, and informational structures underlying the arrow of time, and how does consciousness and observer-dependent perspectives affect temporal asymmetry?

This theme addresses the arrow of time through the lens of observer-dependent limitations, cognitive processes, informational coherence, and emergent temporal experience. It integrates frameworks that challenge strict objectivist views, emphasizing how temporal flow, causality, and irreversibility connect to epistemic constraints, recursive feedback, and layered cognitive access to time. It seeks to reconcile the block universe picture with subjective time asymmetry, addressing foundational issues in the interpretation of quantum mechanics, consciousness, and the meaning of temporal becoming.

Key finding: Introduces TTAC as a layered temporal framework where global block-time coexist with asymmetric observer-dependent temporal flow arising from cognitive modelling and informational constraints; reconciles microphysical... Read more
Key finding: Develops a formalism modeling time as emergent from recursive coherence in observer-coupled quantum systems via the Timeline Coherence Tensor; distinguishes entropic divergence (timeline decoherence) from syntropic... Read more
Key finding: Advocates a positivist stance emphasizing observer participation, Bayesian inference, and incomplete information as fundamental to understanding time's arrow and irreversibility; critiques deterministic interpretations and... Read more
Key finding: Synthesizes competing realist and positivist interpretations of time's arrow, emphasizing that irreversibility and the causal arrow arise from macroscopic observers' incomplete access to microstate information and relevant... Read more
