Beyond minAction.net

About this site

minAction.net is a research programme on a variational principle, written δS_NW = 0: the Network-Weighted Action Principle. It tests that principle in physiology, physics, neural architectures and biology. Its papers, code and validations, including a test that refuted one of its own proposed mechanisms, are published there.

This site is something different. It asks what the same principle might mean outside the laboratory. These essays are reflections, not results of the research programme, and they make no claim the papers would need to support.

The Unseen Architecture: From Cosmic Contraction to Convergent Design

In the distance that often separates the world’s mystical traditions from the mathematics of modern physics, a resonance can be found. It emerges when we place one of the most esoteric concepts of Kabbalistic metaphysics, the Lurianic doctrine of Tzimtzum, or divine contraction, alongside one of the most foundational principles of physical reality: the Law of Conservation of Energy. At first glance, they inhabit different universes of thought. One is a narrative of divine will, consciousness, and metaphysical necessity; the other is a description of an impersonal, mathematically consistent reality. Yet, explored closely, they share an architecture, a correspondence of function and form that suggests a unified framework for understanding not only the nature of our universe, but the reason for its existence.

This exploration proposes a model that begins with this parallel and ends in a theory of cosmic evolution driven by a single, universal directive: a principle of minimum action and maximum impact, termed minAction.net. The framework suggests that the universe we inhabit is not a random statistical accident drawn from an infinite multiverse, but the convergent solution to a deep “computational” search for a stable and meaningful existence: computational in the sense of Konrad Zuse’s Rechnender Raum, a cosmos that computes its own next state,¹ and of John Wheeler’s “it from bit,” in which every physical “it” derives its existence from information.²

Part IThe Symmetric Stage of Creation

Every coherent cosmology must begin with a transition from a state of undifferentiated unity to one of manifest complexity. In the Kabbalistic tradition of Isaac Luria, this primordial state is the Ein Sof (literally, “Without End”), an infinite, unknowable, and absolute unity of divine potential.³ Within this totality, no distinct thing can exist; there is no “here” or “there,” no “before” or “after.” For a finite reality to emerge, the Ein Sof must first perform an act of Tzimtzum, a “contraction” or “concealment” of its own infinite presence.⁴ This act is not a movement in space but a metaphysical withdrawal, creating a conceptual “vacant space” (Chalal) into which the universe can be emanated. This new reality, however, is not severed from its source. It is structured by a remnant or “impression” of the divine, the Reshimu, which provides the foundational laws and ordering principles for the new cosmos.⁵

This metaphysical narrative finds a physical analogue in the modern understanding of our universe’s foundational laws. Physics, too, posits a kind of primordial unity in the total energy of our closed cosmic system. The Law of Conservation of Energy states that this total quantity is immutable; it can be neither created nor destroyed, only transformed.⁶ This law provides the ultimate guarantee of stability for our reality. The insight of Emmy Noether’s theorem is that this conservation law is not arbitrary. It is the direct mathematical consequence of a deeper principle: time-translation symmetry. This symmetry means that the laws of physics are the same at every moment in time. They are constant, reliable, and predictable.

Here the parallel is close. Both frameworks describe the creation of a stable, consistent “stage” for reality to unfold. The Tzimtzum creates a space governed by the reliable structure of the Reshimu; physical law is underpinned by a fundamental time symmetry that guarantees the reliability of the cosmos. Both describe a reality founded on an unchanging, symmetric backdrop.

Part IIThe Paradox of the Asymmetric Play

This symmetric foundation, however, creates a paradox. If the underlying laws of reality are time-symmetric, if the film of physical interactions looks just as plausible played forwards as backwards, why is our lived experience so relentlessly asymmetric? We experience an undeniable “Arrow of Time.” Stars radiate heat, sugar dissolves in water, and living things are born, age, and die. A shattered glass does not spontaneously reassemble itself. This is the Second Law of Thermodynamics, the statistical tendency of systems to move from order (low entropy) to disorder (high entropy).⁷ Our universe has a history, a one-way causal narrative unfolding upon a stage whose fundamental rules suggest no such directionality should exist.

How can a symmetric stage produce such a directional play? What is the engine that drives this one-way process we call “history”?

Part IIIThe Directive: minAction.net

Where the essay says “minAction.net”, it means a principle from that research, stated in the language of physics. An action is the quantity a system adds up along its path over time. Of all the paths open to it, the system takes the one for which that sum is stationary, written δS_NW = 0. The Network-Weighted Action adds up three things at each moment: E, the system’s energy or operating cost; I, the information it holds about its world; and C, the cost of its connections, weighted by A: S_NW = ∫ (E − I + A·C) dt. Because information enters with a minus sign, keeping the sum small does two things at once: it lowers cost and it raises information. The essay names these two pulls E_min and I_max, the least cost for the most effect.

The proposed resolution lies in the universe’s initial conditions and the directive that governs its evolution. The Big Bang left the universe in a state of immense potential tension: very low entropy (highly ordered) and high potential energy. This state is highly improbable. The subsequent history of the cosmos can be read as the process of resolving this tension. In the research, minAction is a physical principle, not a metaphysical one. It is a vertically organising principle: the same action applies at every scale without being rewritten, from molecules to organisms, and from neurons to networks. Carried up to the cosmological scale, it permits a reading of the tension between time-symmetric laws and a one-way arrow of time, and that reading has a metaphysical side. This essay takes up that reading. In it, the universe unfolds along the path of least cost for the most effect.

The directive has a dual nature, giving rise to two distinct, complementary drives:

E_min · minimize cost

In this reading, the drive toward entropy, the physical face of the Second Law of Thermodynamics. It represents the path of least resistance for energy, which is to dissipate, spread out, and move from ordered states to more probable disordered ones. This one-way flow from low to high entropy is the Arrow of Time. It is not a fundamental law itself, but an emergent statistical property of a system following the E_min directive. It is the universe “exhaling.”

I_max · maximize impact, or information

If the universe were governed by E_min alone, it would be a featureless slide into a uniform “heat death.” But as energy flows downhill toward entropy, it is harnessed to build temporary, localized pockets of order and complexity. These structures are impactful and information-rich. I_max is the creative counter-current, the drive to build galaxies, forge heavy elements, and give rise to life and consciousness. These structures do not violate the Second Law; they are efficient mechanisms for increasing the universe’s total entropy, and they do so by creating temporary islands of local order.

The Arrow of Time is thus the shadow cast by E_min, while the complex structures in the cosmos are the work of I_max. minAction.net is proposed as the single engine behind both decay and creation.

Part IVThe Algorithm of Creation: A Relational Architecture

This framework raises the question: how does I_max build complexity? A random search for stable structures would be astronomically inefficient, violating the core tenet of E_min. The proposal here is that it follows a recurring architectural pattern, which we can call the “glial-neural net.”

Generalized from its biological context, this architecture holds that stable, complex systems are composed of two interdependent types of units:

• “Neural” units, the actors: the primary, energy-intensive components that perform the system’s main work (stars undergoing fusion, neurons firing).
• “Glial” units, the regulators: the units that provide the contextual, regulatory, and logistical support that makes the neural units efficient and coherent (gravity organizing stars into a galaxy, astrocytes regulating blood flow to neurons).

Performance and stability are found not in the units themselves, but in the ratio and relationship between them. This relational principle constrains the cosmic search space. The universe does not spend energy building unbalanced systems. It “learns” and propagates architectures where the glial-neural balance creates a positive feedback loop of stability, predictive capacity, and increasing impact. On this view, this is the algorithm I_max uses to build everything from atoms to brains.

ConclusionFrom Fine-Tuning to Convergent Design

This multi-layered framework offers an alternative to one of the most debated ideas in modern cosmology: the multiverse. The “fine-tuning problem,” the observation that the fundamental constants of our universe seem set to values that permit life, is often explained by positing an infinite number of universes, each with a random set of constants, our own being a lucky statistical outcome.

The minAction.net framework offers a different answer: the laws of physics are not a lottery ticket, but the convergent solution to a cosmic optimization problem. On this view, the earliest moments of the universe were a deep search across a vast space of potential physical laws, guided by the directive:

• The E_min constraint filtered out laws that did not produce a stable, self-sustaining reality.
• The I_max driver selected the architecture most capable of generating complexity through the glial-neural algorithm.

The constants we observe would then be not random, but the convergent solution that best satisfies these two imperatives. We would not need an infinite number of failed universes to explain our successful one; one universe, running an optimization, would be enough to find the most stable and impactful configuration.

Read this way, our universe is not a statistical accident. It is the outcome of a cosmos built around a single directive: to exist as simply, and as meaningfully, as possible. The ancient notion of a cosmos born from a purposeful act of limitation finds a modern counterpart in a universe that continually discovers and creates itself through efficient and impactful design.
