Holos: A Framework for Understanding Reality

Citations

Citations are essential to this framework. They link to the important philosophical, scientific, and mathematical work being done by many people, both in recent years and dating back across a long history of ideas, experiments, and observations. What follows is a curated list of sources that have directly informed or inspired the views expressed here.

Overview

Introduction

See: Overview › Introduction

1
  • Interpretations of quantum mechanics Holos is an interpretive framework: it does not add new laws of physics, only a way to understand how a physical description turns into lived experience.
  • Philosophy of physics The study of fundamental questions about space, time, matter, and the relationship between mathematical description and what we take to be real.
  • Structural realism The view that science describes relationships between things, not what they are in themselves. Holos extends this by giving observation a role in making structure lived.
  • Block universe The view that past, present, and future exist as a four-dimensional block. Holos treats observation as what registers this structure as experience.
  • Holos The framework, and the relation it is named for: lawful possibility composed with registration (R = C ⊛ O), marking where structure is lived.

Consciousness

See: Overview › Consciousness

2
  • Hard problem of consciousness Chalmers (1995): why does physical activity produce felt experience at all? Holos does not answer this, but reframes it. Integration is the condition under which a physical system has an inside view.
  • Binding problem How distributed neural activity gives rise to unified experience. Holos frames integration as the boundary where independent parts become a single perspective.
  • Neural correlates of consciousness Search for what in the brain matches experience. Anesthesia switching it off, and recovery switching it back on, fit integration as the condition for being an observer.
  • Global Neuronal Workspace Theory (GNWT) The theory that conscious access happens when a signal lights up and spreads across the brain. Holos treats this as a model of what gets reported, not the deeper threshold (integration) for being an observer at all.
  • Integrated Information Theory IIT: each experience is the cause-effect structure of a maximally integrated system, and Φ measures how integrated it is. Holos borrows integration as the condition for being an observer, not IIT's full theory.
  • Qualia The felt character of experience. Holos does not reduce it to Φ but treats integration as the condition for experience from the inside.
  • Panpsychism Consciousness as fundamental in matter. Holos rejects universal panpsychism in favor of a threshold (Φ ≥ Φ_c) so that not everything is an observer.
  • Kagan et al. (2022), In vitro neurons learn and exhibit sentience when embodied in a simulated game-world Neuron: networks of cultured neurons grown on a chip, wired to a simple game of Pong, learned to play better through closed-loop feedback. Such dishes show that neural tissue can form adaptive feedback loops outside a full organism. The paper's word "sentience" was widely criticized, and these systems do not demonstrate consciousness. They are a platform for studying minimal neural integration and learning.

Spacetime

See: Overview › Spacetime

3
  • The Big Bang The present universe expanded and cooled from an extremely hot, dense early state.
  • Accelerating Expansion of the Universe The expansion of the universe is accelerating with time.
  • Spacetime A mathematical model that fuses the three dimensions of space and the one dimension of time.
  • General Relativity Describes gravity as the warping of spacetime by mass and energy.
  • Eternalism Time as an unchanging four-dimensional block in which all moments exist tenselessly, none privileged as now.
  • Block Universe Model The view that past, present, and future exist together as one four-dimensional block. All events are fixed in spacetime. Nothing, consciousness included, moves through it.
  • Relativity of Simultaneity Whether two distant events happen at the same time depends on how the observer is moving.
  • Light Cone The boundary of all possible paths that light can take from a given event, defining the causal structure of spacetime.
  • Retrocausality The idea that future events can influence past ones. Holos rejects it. The quantum eraser needs no backward influence, only the sorting of records made later.
  • Quantum Eraser Experiment The screen pattern never changes. Interference appears only when recorded hits are sorted using later measurements. Ordinary quantum mechanics predicts every result, with nothing traveling backward in time.
  • Kim et al. (2000), A delayed "choice" quantum eraser Physical Review Letters: the experiment behind the eraser figure. Linked pairs of photons (entangled pairs). Interference shows up only in subsets of screen hits sorted by their partners' later records.
  • Observer Effect The disturbance of a system by the physical act of measuring it. Holos denies any further, consciousness-linked disturbance. Observation changes no physics.
  • Copenhagen Interpretation The traditional reading: a measurement yields one definite outcome, and the wavefunction is updated ("collapses") to match. Versions differ on whether that update is physical or only a change in knowledge. Holos without collapse, the version defended here, rejects a physical collapse. Evolution stays unitary, and branches with observers are lived from within.
  • Quantum Darwinism Zurek (2009, Nature Physics): the environment makes many redundant copies of information about certain states, so many observers can learn the same outcome without disturbing it.
  • Relational Quantum Mechanics The properties of quantum systems are not absolute but relative to other physical systems, not only human observers.
  • Von Neumann-Wigner Interpretation Consciousness causes collapse (Wigner, 1961). The view Holos bets against. A consciousness-linked deviation would falsify Holos without collapse, leaving Holos with collapse, which shares its core (the standing bet).

Infinity

See: Overview › Infinity

4
  • Gravitational singularity Where general relativity predicts infinite density. Most physicists read it as the place the theory stops working, the same lesson as the ultraviolet catastrophe.
  • Projective Geometry A branch of geometry studying what stays the same when the point of view changes. Parallel lines meet at infinity.
  • Ultraviolet catastrophe Classical physics predicted infinite radiation from hot objects. The infinity signaled a broken description, and the fix, energy in discrete packets, became the foundation of quantum theory.
  • Riemann Sphere The plane plus one point at infinity, closing an unbounded surface into a finite sphere.
  • Point at Infinity In projective geometry, each family of parallel lines meets at its own point at infinity. On the Riemann sphere, every direction meets at one point, closing an endless plane into a finite shape.

Omega

See: Overview › Omega

5
  • Everett (1957), Relative state formulation of quantum mechanics Reviews of Modern Physics: the origin of the universal wave function. Physically, Holos's Omega is this one universal quantum state.
  • Everett's relative-state formulation (Stanford Encyclopedia of Philosophy) Reference overview of Everett's theory and its interpretations.
  • Panentheism The belief that the divine intersects every part of the universe and also extends beyond space and time.
  • Brahman The pervasive, infinite, eternal truth, consciousness and bliss which does not change, yet is the cause of all changes.
  • Omega Point Teilhard de Chardin, and later Frank Tipler: a future event in which the entirety of the universe spirals toward a final point of unification. Holos borrows the name, not the idea. Its Omega is the whole, not an endpoint.
  • Advaita Vedanta The nondual school of Indian philosophy holding that there is one experiencer, and that each individual consciousness is that one seen through a local form. A named ancestor of the Holos monist reading.
  • Baruch Spinoza Philosopher of substance monism: one substance, of which all finite things are modes or expressions.
  • George Berkeley Idealist philosopher who grounded the persistence of the unobserved world in a perceiver that never looks away (God).
  • Schrödinger (1958), Mind and Matter Cambridge University Press: "Consciousness is a singular of which the plural is unknown." A founder of quantum mechanics who held, by way of Vedanta, that there is one mind. He proposed no threshold. Holos shares only the one experiencer.
  • Open individualism Daniel Kolak (I Am You, 2004): we are all the same subject. The nearest modern relative of the Holos monist reading, which calls the local person a self and the one subject the experiencer.
  • Vertiginous question Why, of all the subjects there are, am I this one? Some call it a brute fact. Indexical accounts say nothing needs explaining because "I" picks out the asker. On the Holos monist reading nothing needs explaining because the one experiencer is each.
  • Perry (1979), The problem of the essential indexical Noûs: the classic account of "I", "here", and "now" as words that pick out the speaker's own position. The strongest rival reply to the vertiginous question, stated on the site beside the monist one.
  • Teletransportation paradox Parfit's duplication puzzle: if two perfect copies of you are made, which is you? On the Holos monist reading, both, with no remainder. Parfit's own answer is that identity is not what matters.
  • Parfit (1984), Reasons and Persons Oxford University Press: argues that identity is not what matters in survival, and that seeing this weakens the line between self-interest and concern for others. Holos cites it on identity only and draws no ethical conclusion of its own.

Aliens

  • Rare Earth hypothesis Complex life is rare, so the silence is literal emptiness. A column in the Fermi comparison table.
  • Great Filter Robin Hanson: some step stops almost every civilization before it spreads. A column in the Fermi comparison table.
  • Aestivation hypothesis Civilizations sleep until the universe cools, when computing is cheaper. A column in the Fermi comparison table. Contested by Bennett, Hanson, and Riedel (2019).
  • Carroll-Nellenback et al. (2019), The Fermi paradox and the Aurora effect The Astronomical Journal: models galactic settlement with finite probe speeds and settlement lifetimes. Whether the galaxy fills or stays patchy turns on those rates, the setting in which the Integration Hypothesis's bet about motives becomes numbers.
  • Jevons paradox Efficiency gains tend to raise total consumption. The objection to the Integration Hypothesis. Its answer is that light-speed delay caps one mind's useful size, so growth becomes more compact nodes near home, harvesting the home star.
  • Project Hephaistos Uppsala-led search for waste heat from partial Dyson spheres around individual stars, the star-by-star channel the Integration Hypothesis points to.
  • Suazo et al. (2024), Project Hephaistos II: Dyson sphere candidates from Gaia DR3, 2MASS, and WISE Monthly Notices of the Royal Astronomical Society: about five million stars searched. Seven M-dwarf candidates with unexplained infrared excess.
  • Zackrisson et al. (2026), Project Hephaistos IV: JWST observations of two Dyson sphere candidates Preprint, not yet peer reviewed: JWST traces the infrared excess of two candidates to background galaxies.
  • Korn et al. (2026), Project Hephaistos III: characterizing anomalous infrared sources Preprint, not yet peer reviewed: no clear explanation yet for the remaining candidates. Dust or background galaxies remain possible.
  • Gaia Data Release 4 ESA, due 2 December 2026: the next star-by-star census, extending the base for waste-heat searches around individual stars.
  • PRIMA (Probe far-Infrared Mission for Astrophysics) NASA's far-infrared space telescope, selected in September 2026 for launch around 2033. The main future tool for the cold half of the waste-heat search.
  • Fermi Paradox The discrepancy between the lack of evidence for extraterrestrial life and the apparently high likelihood of its existence. The Integration Hypothesis, a companion to Holos, reframes this silence. Advancement favors compact, efficient integration over expansion and broadcast, so maturity coincides with electromagnetic quiet.
  • Early broadcasting phase The early biological and broadcasting phase of a civilization. Any hurdle (abiogenesis, nuclear war, coordination failure) that stops a civilization before deep integration is an early filter relative to true maturity.
  • Light-speed latency A high-integration intelligence cannot function with years of light-speed lag between star systems. Independent interstellar colonies either fragment into less-capable outposts or the civilization turns inward, deepening local integration instead of expanding.
  • Dark Nodes One hypothesized mature form: compact, non-luminous systems built from ordinary matter, a trace population detectable, if at all, by gravity and warm waste heat rather than light (the Teeming Dark). Much of a civilization's heat may instead leave cold, far from its star. Not cosmological dark matter, which predates any possible life.
  • Waste-heat SETI (the Ĝ survey) Wright et al. (2014): infrared searches for civilizations with large energy supplies, built on the principle that waste heat is the one emission technology cannot eliminate. This is the warm half of the search channel the Teeming Dark aligns with. Silent, but warmer than space. A channel, not a fingerprint. Warm dark masses are also what failed stars and cooled remnants look like.
  • Ephemeralization R. Buckminster Fuller (1938): the process of doing "more and more with less and less" until intelligence can "do everything with nothing". The Integration Hypothesis extends this to civilizations turning inward. Fuller did not.
  • The Transcension Hypothesis John Smart (2012, Acta Astronautica 78:55. Web essay 2011): advanced civilizations migrate to inner space for efficiency. Holos shares the inward-turn conclusion. Mature systems remain ordinary matter that has stopped shining.
  • Substrate independence (multiple realizability) The view that a mind could run on different kinds of physical material, not just brains. Holos agrees that pattern matters more than material, without claiming minds can run on anything beyond ordinary matter.
  • Dark matter The unexplained "missing mass" holding galaxies together. Holos takes no position on its particle nature and does not identify it with life. Its fingerprints in the CMB predate stars, chemistry, and any possible builder. Mature civilizations belong instead to the non-luminous side of ordinary matter.
  • Dyson sphere A hypothetical megastructure that would encompass a star to capture its energy. Their absence is consistent with the Integration Hypothesis, which bets civilizations stay near home rather than spread between stars. A thin, cold swarm far from its star would still fit. Thermodynamics still applies. Waste heat, not visible structure, is the unavoidable search target.
  • Dyson (1960), Search for artificial stellar sources of infra-red radiation Science: the original proposal. A civilization using a star's energy must shed it as waste heat, so the place to look is the infrared. The search channel the Integration Hypothesis and Project Hephaistos both use.

The Teeming Dark

See: Overview › The Teeming Dark

7
  • Black hole A limited precedent for the Teeming Dark: the most compact masses need not shine and are found by gravity alone. The precedent is about compactness, not integration.
  • Massive compact halo object (MACHO) Microlensing surveys watched millions of stars for dark compact masses and found too few to make up a large hidden population. Dark Nodes can only be a trace population.
  • Missing baryon problem Surveys, most recently using fast radio bursts (Macquart et al. 2020, Nature. Connor et al. 2025, Nature Astronomy), have now located nearly all the ordinary matter the early universe records, leaving room for hidden built structures only within the measurement uncertainties.
  • Landauer (1961), Irreversibility and heat generation in the computing process IBM Journal of Research and Development: erasing information has an unavoidable heat cost. Long-running computers must correct errors, which means erasing, so they shed heat, though careful designs can keep the cost small.
  • Garrett (2026), Slysh haloes: the waste heat of cold computing as a submillimetre technosignature Preprint, not yet peer reviewed. Erasing information costs less in the cold, so mature civilizations may compute at about 5 to 30 K, far from their star, with a faint, featureless far-infrared glow. Archived dust-disk surveys could in principle test it near 10²⁰ watts. It does not weigh light delay. The reason Holos widened its signature to the cold far infrared.
  • Euclid Mission March 2025 Q1 data: 26M galaxies, precision mass mapping. Compact mass peaks with weak visible counterparts become interesting only after conventional explanations fail, and only alongside an infrared excess.
  • James Webb Space Telescope (JWST) Deep-field mass structure under active study. For Holos, a candidate Dark Node requires gravity plus faint warmth, not gravity alone.
  • Baryon Protons and neutrons. Astronomers use "baryonic" to mean ordinary matter. Dark Nodes remain baryonic, built matter that stops shining.

Why Are We Here?

See: Overview › Why Are We Here?

8
  • Quantum entanglement Particles whose joint state cannot be split into separate states, however far apart they are. The strongest physical hint behind the section's bold reading that separation is not fundamental.
  • Holism and nonseparability in physics (Stanford Encyclopedia of Philosophy) Reference overview of the view that entangled systems are not composed of independently existing parts. Holos goes one step further and takes that oneness as more basic than the separations.
  • Participatory Anthropic Principle John Wheeler: the universe, as a condition of its existence, must be observed. As a "self-excited circuit", it needs observers to bring it into being. Holos keeps the intuition of one whole but rejects this. Observers register structure. They do not create it.

Logic

Primitives

See: Logic › Primitives

9
  • Information The differentiation between possible states of a system, in the physics sense that Axiom 2 conserves. How distinguishable states are, whether or not the difference matters to anything. A related, narrower idea is Gregory Bateson's "difference that makes a difference."
  • Phase Space The space of all possible states of a classical system (its quantum counterpart is Hilbert space). Creation is what physics actually produces, every branch of the one quantum state. Observation registers from within, where observers exist, and selects none.
  • Invariant (physics) In physics, an invariant is a quantity that stays the same when you change viewpoint, like the speed of light. Holos builds on this. What is real is stable relationships, not fixed properties things carry on their own. ⊛ concerns where that structure is lived, not how it changes over time.

Axioms

See: Logic › Axioms

10
  • Ontology The study of what exists. Holos separates structure, which exists whether or not it is lived, from presence, which requires observers.
  • Epistemology The study of knowledge and belief. Holos distinguishes epistemic inference (what we know) from ontological presence (what is lived).

Foundations

See: Logic › Foundations

11
  • Flatland Edwin Abbott (1884): a sphere passing through a flat world appears to its inhabitants as a changing circle, an event in time. From three dimensions it is one whole. The picture behind Proposition IV. Each higher description closes what a lower one leaves open.
  • Ney and Albert, eds. (2013), The Wave Function: Essays on the Metaphysics of Quantum Mechanics Oxford University Press: essays on wave-function realism, the view that the vast space where the quantum state lives is the most real level. One of the higher descriptions in Proposition IV. Holos does not depend on the view.
  • Probability Theory ⊛ is not probability weighting: the Born weights are structural facts within C, while ⊛ concerns which structures are lived.
  • Wave Function Collapse ⊛ is not a physical collapse happening over time. No outcome is picked. Each branch with an observer is lived from within.
  • Bayesian Inference Bayesian updating describes belief revision (about knowledge, or epistemic). ⊛ describes where structure is lived (about what exists, or ontological).
  • Equivalence Relation Lit and unlit partition spacetime into two classes: a structural classification, not a transition between states.

Threshold

Relationship to Physics

See: Logic › Relationship to Physics

13
  • Unitarity (physics) Unitary evolution never collapses. Holos without collapse, the version defended here, preserves it fully. Nothing collapses, nothing is selected, and unobserved branches remain in Creation as unlit structure.
  • Hilbert Space The mathematical space of all possible quantum states. Holos deletes no branches from it. The Born weights are structural facts about it.
  • Schrödinger Equation Φ does not replace or modify the Schrödinger equation. It marks where experience occurs and leaves the quantum math untouched.
  • Quantum Mechanics Holos leaves quantum mechanics untouched. Φ marks where registration occurs. It adds no constraint to the physics.
  • Born rule Max Born (1926): quantum probabilities are squared amplitudes, one of the best-tested rules in physics. In Holos the weights are structural facts within C, setting each observer's odds rather than measuring how much experience a branch carries. Almost all of the weight, not every observer, sees Born statistics.
  • Gleason's theorem Andrew Gleason (1957): given its assumptions, any consistent assignment of probabilities to measurement outcomes takes the Born-rule form. It constrains the odds but does not by itself say how an observer inside a branch should set them. Holos adds no new mathematics.
  • Sebens and Carroll (2018), Self-locating uncertainty and the origin of probability in Everettian quantum mechanics British Journal for the Philosophy of Science: after branching and before looking, an observer is uncertain which branch they are in, and the Born weights are the rational odds. Holos adopts this reading. Counting fails, weight is the measure physics supplies, and the last step is their epistemic separability principle, widely discussed and still debated.
  • Ontology Experience is lived only inside observers. The causal pasts they draw on are lit. The rest remains unlit structure. The underlying quantum math is unaltered.

Notation

See: Logic › Notation

14
  • Information Theory Sending information assumes a causal signal passes between places; ⊛ sends nothing. It concerns which histories are lived, not which signals travel.
  • Measurement in Quantum Mechanics Measurement models the physical interaction between systems. Observation in Holos is registration from within. It selects nothing and alters no interaction.
  • Hilbert Space In quantum physics, a system's state is a vector in a very large (often infinite-dimensional) space. Some researchers argue ordinary 3D space emerges from this structure. That view is debated, and Holos does not depend on it.

Comparison

See: Logic › Comparison

15
  • Goff (2017), Consciousness and Fundamental Reality Oxford University Press: the case for priority cosmopsychism, a conscious cosmos from which individual minds derive. Holos shares the single ground but makes no claim either way about an experience of the cosmos as a whole.
  • Nagasawa and Wager (2016), Panpsychism and priority cosmopsychism In Brüntrup and Jaskolla, eds., Panpsychism (Oxford University Press). Sets out priority cosmopsychism and the problem it faces of how one cosmic subject yields many individual ones (the decombination problem). Holos's section on walled-off perspectives answers the same problem.
  • Russellian monism (Stanford Encyclopedia of Philosophy) Physics describes structure. Experience is the intrinsic nature of that structure. Holos agrees experience is the inside of physical activity, but only above the threshold.
  • Dual-aspect monism Mind and matter as two aspects of one underlying reality, from Spinoza to the present. The modern family of Axiom 4. Holos is a two-sided monism with a threshold. The two sides appear only above it.
  • Physicalism (Stanford Encyclopedia of Philosophy) The view that everything is physical, with the mental grounded in the physical. Holos agrees physics fixes every fact, so copies match in every possible world, but holds that neither side of an observer's activity is grounded in the other. Some will still classify it as physicalism. The site says why it does not.
  • Phenomenal concept strategy The explanatory gap lies between two ways of describing one thing, not between two things. Developed by physicalists (Loar, Papineau, Balog). Axiom 4's floor-plan argument is a version of it, borrowed without the physicalist conclusion.
  • Antony (2006), Vagueness and the metaphysics of consciousness Philosophical Studies: consciousness cannot be vague. Most who accept the argument conclude panpsychism. The rest posit an exact cutoff. Holos rejects the premise and accepts a narrow twilight between clear cases.
  • Schwitzgebel (2023), Borderline consciousness Philosophical Studies: argues that borderline cases of experience are coherent. They cannot be pictured from the inside, since picturing an experience makes it definite, but that limits imagination, not reality. The reply Holos gives to the no-vagueness argument.
  • Rosenberg (2004), A Place for Consciousness Oxford University Press: poses the boundary problem, what fixes where one subject ends. Holos answers with its maximality condition. One peak of integration, one perspective.
  • Global workspace theory Conscious access as brain-wide broadcast. A column in the Holos theories-of-mind table.
  • Illusionism Experience as usually conceived does not exist. A column in the Holos theories-of-mind table. Holos rejects it.
  • Frankish (2016), Illusionism as a theory of consciousness Journal of Consciousness Studies 23(11-12): the standard statement of illusionism. We are conscious, but experience lacks the special inner qualities it seems to have. The task is to explain why it seems to have them.
  • Seth and Bayne (2022), Theories of consciousness Nature Reviews Neuroscience: a readable survey of the main scientific theories (global workspace, integrated information, higher-order, predictive processing) and how they might be tested. Background for the theories-of-mind table.
  • Many-worlds interpretation Everett (1957): every outcome of a quantum event with nonzero weight happens, each in its own branch. Holos agrees. What it adds is a threshold for who counts as an observer, and a reading of the whole as one experiencer.
  • Relational quantum mechanics Rovelli (1996): quantum properties are relative to observers. Holos aligns on relational facts, but keeps the universal state RQM rejects, and adds a threshold (Φ ≥ Φ_c) for what counts as an observer.
  • QBism Fuchs, Mermin, and Schack (2014, American Journal of Physics): quantum probabilities are an agent's personal degrees of belief about their future experiences. Holos is ontological (what is lived) rather than epistemic (what agents believe).
  • Copenhagen interpretation The traditional (textbook) interpretation, with collapse at measurement. Holos without collapse, the version defended here, drops it. Evolution stays unitary, branches remain, and those with observers are lived from within.
  • Objective collapse theories Theories in which collapse is a physical process that needs no observer: large objects settle into one outcome on their own. Holos without collapse rejects them. Any confirmed collapse would falsify that version and leave Holos with collapse, declared in advance. A consciousness-linked collapse would make the threshold the collapse point (the standing bet), while a size-based one would leave the threshold dynamically inert. No search has found one. The parameter-free Diósi-Penrose model is ruled out (Donadi et al. 2021).

  • Dynamics (physics) Holos does not propose new dynamical laws. It makes structural claims about where structure is lived (R = C ⊛ O).
  • Ontology Predictions about where structure is lived. Observers register the block universe from within. They do not hold it together.
  • Block universe The structural layer of Holos: tenseless and observer-independent. Observers register it from within. Its consistency does not depend on them.
  • Anthropic principle Holos keeps what exists apart from where it is lived: observer-free universes or branches exist as structure but are never lived, and nothing is selected or filtered.
  • Multiverse Branches where nothing could live exist as structure, but in Holos they are never lived (no system reaches Φ_c).

Commitments

See: Predictions › Commitments

17
  • Integrated Information Theory (IIT) Holos borrows Φ as a measure of integration, not IIT's identity claim. Crossing Φ_c is where experience occurs. PCI is a practical proxy.
  • Panpsychism Holos distinguishes itself from universal panpsychism (experience in all matter) and from illusionism (experience lacks the inner qualities it seems to have).
  • Illusionism (consciousness) The view that experience does not have the special inner qualities it seems to have. What exists is the brain's representation of such qualities (Frankish 2016). Holos rejects it. Experience is the one fact the framework starts from.
  • Qualia The felt character of experience. Holos locates qualia in systems that meet the observer requirements. Below Φ_c there is processing without experience.
  • Casali et al. (2013), A theoretically based index of consciousness independent of sensory processing and behavior Science Translational Medicine: introduces the Perturbational Complexity Index (PCI). Stimulate the brain with a magnetic pulse and measure how complex its echo is. An IIT-inspired metric with an empirically calibrated cutoff between conscious and unconscious states. Holos treats it as a proxy for integration, not a detector of presence.
  • Phase transition Holos hypothesizes that the onset of experience is a genuine transition, steep but with a narrow twilight in any finite system. A steep change alone would not confirm this, since ordinary models predict tipping points too.

Testability and Its Limits

Speculation

See: Predictions › Speculation

19
  • Phase transition A speculative reading: civilizational integration may advance in jumps rather than smoothly, as light-speed delay and waste heat reshape what can be coordinated.
  • Fermi paradox A companion hypothesis to Holos, not part of its core: the Integration Hypothesis and Going Quiet. Mature civilizations are silent in light. The unavoidable observables are gravity and waste heat.
  • Hanson et al. (2021), If loud aliens explain human earliness, quiet aliens are also rare The Astrophysical Journal: the grabby aliens model. Visible, expanding civilizations exist but have not reached us, and we are early. Named on the site as the main rival to the Integration Hypothesis.
  • Griffith et al. (2015), The Ĝ infrared search, III The Astrophysical Journal Supplement: of about 100,000 galaxies surveyed with WISE, none hosts a civilization reprocessing more than 85% of its starlight into waste heat.
  • Zoo hypothesis The idea that mature civilizations deliberately leave young ones alone. For Holos, non-contact needs no agreement. Leaving a young civilization alone costs nothing, while contact takes effort.
