Greetings to you curious thinker.

In my journeys through theory and systems thinking as a user experience and game designer, I have uncovered a number of foundational questions that relate to the most fundamental properties of reality. Why is everything so intricate, ordered and beautiful in a sea of chaos? Why are certain things impossible and other things counterintuitively possible? Why does everything cohere? These questions lead me down a deep rabbit hole and ultimately brought me to a number of scientific discoveries that provide clues to finding the answers. These clues could be thought of as their own field of study which I now call Causology.

What is causology? At its simplest, you might say it's the study of cause and effect itself. At a deeper level, you could say it's a deeper look at the underpinnings of existence- covering everything from quantum physics, philosophy, thermodynamics, emergence, computation and anything tangential.

Is this a new idea? No it's not. Cause and effect has been a deeply studied aspect of science throughout history. In fact it's a core part of the scientific method which demands empirical observable evidence for a given axiom. But has causality been carved into its own field that exists as a specialized area of study in its own right? Not until now.

Core Principles of Causology

Here are the fundamental axioms I would put forth as the pillars of causology:

1. The Principle of Causal Consistency (The Law of Non-Contradiction)
   • Core Idea: The universe will never collapse into a state that results in a logical paradox. The requirement for self-consistency is the most fundamental law, overriding even a strictly linear perception of cause and effect. Reality will always resolve into a state that is coherent and non-contradictory, even if it requires selecting a history that seems counter-intuitive or even appears to bypass time's arrow.
   • Grounding in Established Science:
     • The Delayed-Choice Quantum Eraser: This is the flagship experiment. It demonstrates that a future measurement can influence a past event, but the final, complete picture is always self-consistent. The universe seems to "wait" until all information is in before collapsing into a single, non-paradoxical history.
     • Novikov Self-Consistency Principle: Developed for General Relativity, this principle states that if time travel to the past is possible, any event that occurs must be self-consistent. You cannot, for example, go back in time and kill your grandfather, because the universe would only allow for histories where you fail, change your mind, or where your actions were part of a stable, consistent loop all along.
     • Transactional Interpretation of Quantum Mechanics (TIQM): This interpretation, proposed by physicist John G. Cramer, describes every quantum interaction as a "handshake" across spacetime between an emitter and an absorber. The emitter produces a forward-traveling "offer wave," and the absorber returns a backward-traveling "confirmation wave." The transaction—the actual exchange of energy and momentum—is only completed if the two waves meet and form a self-consistent "handshake." This provides a physical mechanism for how the universe might "negotiate" a non-contradictory outcome between past and future.
     • The Elitzur-Vaidman Bomb-testing Problem: This thought experiment, which has real-world analogues, demonstrates the possibility of "interaction-free measurement." It outlines a method for detecting a photon-triggered bomb without the photon ever interacting with the trigger. The mere possibility of the interaction is enough to alter the experimental outcome, allowing information to be gained without a direct causal link. This supports the idea that the universe can "check" for potential contradictions in a timeline without having to fully play it out.
     • The Aharonov-Bohm Effect: This experimentally verified effect shows that a charged particle is influenced by a magnetic field it never physically enters. By proving that the underlying electromagnetic potentials are more fundamental than the fields themselves, it suggests that reality is governed by an invisible, non-local structure. This structure can enforce consistency rules on a particle's behavior without requiring direct, classical interaction.
2. The Principle of Emergent Resolution (The Unresolved Contrast Principle or UCP)
   • Core Idea: Complexity and order arise as a way for a system to resolve a fundamental tension or "unresolved contrast." The universe is driven to create emergent structures, from atoms to galaxies to life, because these structures represent more stable, energy-efficient configurations than uniform chaos. Emergence is the universe's primary strategy for resolving instability.
   • Grounding in Established Science:
     • Thermodynamics & Free Energy Minimization: This is the direct physical mechanism. A system will always tend toward a state of minimum "free energy." Often, the most stable way to do this is not to descend into uniform heat (entropy), but to form complex, ordered structures that are more efficient at dissipating energy gradients. Life itself is a prime example of resolving the contrast between the high energy from the sun and the low energy of deep space.
     • Phase Transitions: When water freezes into a complex ice crystal, it's resolving the contrast between temperature and molecular bonds. The emergent crystalline structure is a more stable, lower-energy state. This principle is fundamental to condensed matter physics.
     • Dissipative Structures: This concept, for which physicist Ilya Prigogine won the Nobel Prize, formally describes how order can arise from chaos. When an open system is pushed far from thermodynamic equilibrium by a continuous flow of energy, it can spontaneously organize itself into complex, stable patterns. These "dissipative structures" maintain their existence by constantly taking in high-grade energy and dissipating it as low-grade heat. Hurricanes, convection cells in boiling water, and living organisms are all real-world examples. This provides a formal theoretical basis for how resolving a strong energy gradient (an "unresolved contrast") naturally leads to emergent complexity.
     • The Free Energy Principle (FEP): Originating in neuroscience with Karl Friston, this is a powerful modern framework that describes how self-organizing systems, especially living ones, maintain their structure. It posits that these systems act to minimize "free energy," which can be understood as minimizing uncertainty or "surprise." They do this by constantly updating their internal models of the world to better predict their environment. This directly parallels the UCP by framing emergence as a fundamental drive to resolve the "contrast" between what a system expects and what it actually senses, thereby reducing uncertainty and maintaining order.
3. The Principle of Scale Relativity
   • Core Idea: The laws of physics are not absolute but are dependent on the scale at which they are observed. Reality has a different texture and follows different effective rules at the quantum, human, and cosmic scales. "Movement" through this scale dimension is a real, physical process that governs the transition between these different descriptive regimes.
   • Grounding in Established Science:
     • Renormalization Group (RG) Theory: This is the mathematical cornerstone. The RG is a formal method in quantum field theory that describes precisely how the effective laws of physics "flow" and change as one changes the scale of observation.
     • Fractal Geometry: As explored in Nottale's work, this provides the geometric picture. The "jagged" fractal nature of the quantum world is smoothed out ("coarse-grained") as you move up in scale, leading to the smooth, classical geometry we perceive.
     • Scale Space Theory: Originating in computer vision, this framework provides a compelling analogy for how an observer might perceive a scale-relative reality. It models a visual scene at multiple levels of resolution simultaneously, from fine-grained details to coarse, large-scale structures. This directly parallels how the "jagged" quantum world is perceived as smooth at the macroscopic level. It grounds Scale Relativity not just in physical law, but in the very process of observation and information processing, suggesting that to "see" at a different scale is to apply a different resolving filter to reality.
     • Effective Field Theory (EFT): This is the practical philosophical and mathematical framework that modern physicists use to embody Scale Relativity. EFT states that you can create an extremely accurate theory for a specific energy scale (e.g., atomic physics) without needing to know the complete details of the theory at much higher energies (e.g., quantum gravity). It formalizes the idea that the laws of physics can be understood in "layers," where each layer is valid within its own domain of scale. 
4. The Principle of Informational Thermodynamics
   • Core Idea: Information is physical, and manipulating it has an energetic cost. Creating, maintaining, or erasing a state of reality requires energy. A "collapsed" macroscopic reality has a form of informational inertia, and changing it is not a trivial act but a thermodynamic process.
   • Grounding in Established Science:
     • Landauer's Principle: This is a fundamental law from the physics of information. It states that there is a minimum possible amount of energy required to erase one bit of information. This directly links information to thermodynamics and proves that changing a system's informational state has a real, physical energy cost.
     • The Physics of Computation: Building on Landauer's work, this field studies the energy costs of processing information. It provides a rigorous basis for the idea that maintaining the "coherence" of a complex system against entropic decay requires a constant expenditure of energy.
     • Maxwell's Demon & Information Erasure: This famous thought experiment from the 19th century posed a major challenge to the Second Law of Thermodynamics. A tiny "demon" could theoretically sort hot and cold molecules into separate chambers, decreasing entropy without doing any work. The paradox was finally resolved in the 20th century by demonstrating that the demon's memory is a physical system. The act of observing molecules and storing that information fills the demon's memory. To continue operating, the demon must erase its memory to make room for new information. According to Landauer's Principle, this act of information erasure necessarily dissipates heat into the environment, increasing entropy and perfectly balancing the books. This isn't just theory; experiments with "demonic" devices have confirmed this link between information, memory, and thermodynamics.
5. The Principle of Universal Computation
   • Core Idea: The universe, at its most fundamental level, operates as a computational system. The progression of time and the evolution of physical states are not merely analogous to a computation, but are the result of an underlying information-processing substrate that computes the next state of the universe based on a set of fixed rules and its current state.
   • Grounding in Established Science:
     • The Bekenstein Bound & The Holographic Principle: The Bekenstein Bound is a rigorously derived upper limit on the amount of information that can be contained within any finite region of space. It demonstrates that spacetime is not infinitely detailed but has a finite information density. This implies that reality must be discrete and "digitized" at the fundamental (Planck) scale. A system with a finite information content is, by definition, computable. The Holographic Principle extends this, suggesting this finite information can be fully described on a lower-dimensional boundary, further reinforcing the idea of spacetime as an information-processing medium.
     • Cellular Automata: This is a well-established field of mathematics and computation that studies discrete, rule-based systems. Famous examples like Conway's Game of Life provide a concrete, demonstrable proof-of-concept that incredibly complex, dynamic, and seemingly unpredictable universes can emerge from the repeated application of a few simple, local rules. They show how the richness we observe in our world could plausibly arise from an underlying computational substrate, without needing a complex top-down design.
     • The Space of All Possible Computations: This concept, rooted in the foundational work of Alan Turing, refers to the abstract landscape containing every possible algorithm or program. In this view, our universe can be understood as one specific, highly complex computation being executed from this vast yet formally defined space (effectively it could be thought of as a “Computational Megaverse”). The "interconnection" between all possible realities is not speculative but is based on the shared, universal laws of computation itself.
     • Computational Irreducibility: This is the principle, proven by Alan Turing's solution to the Halting Problem, that for many complex systems, there is no predictive shortcut. The only way to know the future state of the system is to execute the computation step-by-step. In a computational universe, this would manifest as a profound form of "cross-scale entanglement," where the ultimate fate of a local system is inextricably linked to the global state of the entire universal computation. This provides a formal, logical basis for a deep interconnectedness that makes the behavior of any part dependent on the evolution of the whole.
