## The Claim

The universe's constants sit in a hairline band. Stars burn. Carbon forms. Atoms hold together. Tweak any dial by a few percent and stars die. Carbon never forms. Atoms fly apart. You observe this universe because no other universe permits observers. This is not explanation. This is selection. The anthropic principle names the selection effect. It does not explain the values. It tells you why you are asking. [SOURCE:prigogine-1977|type:gradient] [SOURCE:schrodinger-1944|type:negentropy]

## Definitions

- Fine-tuning: Constants occupy a razor-thin range that permits matter, stars, and life.
- Anthropic principle: You observe only universes where observers can exist.
- Selection effect: Your sample is biased by your own existence.
- Fundamental constants: Numbers that fix the strength of forces and the mass of particles.
- Meta-empirical: Beyond direct observation; you reason from what you cannot see.
- Observer entanglement: The observer is not separable from the observed in quantum measurement. [SOURCE:shannon-1948|type:information] [SOURCE:landauer-1961|type:physical-cost]

## The Logic

You need stars to forge carbon. You need carbon to build life. You need life to ask questions. The universe holds six key numbers. Gravity's strength. The strong nuclear force. The weak force. The fine-structure constant. The ratio of electron to proton mass. The cosmological constant. Each sits in a razor-thin band. Martin Rees named them in 1999. Change the strong force by 2%. Hydrogen never fuses into helium. Change the electromagnetic force by 4%. Stars never ignite. Change the cosmological constant by a factor of ten. The universe expands too fast for galaxies. You would not exist to read this. [SOURCE:england-2013|type:dissipation] [SOURCE:noether-1918|type:symmetry]

The logic is structural. You are a consequence of the constants. The constants are not a consequence of you. The anthropic principle does not reverse causality. It notes a necessary condition. It does not supply a sufficient one. [SOURCE:godel-1931|type:recursion] [SOURCE:turing-1936|type:computation]

## The Evidence

Brandon Carter coined the anthropic principle in 1974. He worked at Cambridge. He asked why the large-number coincidences of cosmology exist. John Barrow and Frank Tipler wrote "The Anthropic Cosmological Principle" in 1986. They cataloged every physical constant that permits life. Martin Rees wrote "Just Six Numbers" in 1999. He showed that the cosmological constant sits at 10^-120 of its natural value. That is the most extreme fine-tuning known in physics. John Wheeler pushed further. He proposed "it from bit": every physical quantity derives from observation. The observer participates in the existence of the observed. This is not mysticism. This is quantum mechanics.

The parameters are ~31 free numbers in the Standard Model plus cosmology. Several appear tuned to values that permit complexity. The cosmological constant controls the expansion rate. Its tuning is the most extreme. The Higgs mass controls particle masses. The hierarchy problem is the most theoretically pressing. The fine-structure constant controls electromagnetic strength. A ~4% variation breaks stellar nucleosynthesis. The electron-proton mass ratio controls chemistry. An order-unity variation erases atoms as we know them.

## The Tension

Fine-tuning contradicts symmetry. This is the deepest open problem in the convergence catalogue. Symmetry implies conservation laws are fundamental and necessary. [SOURCE:noether-1918|type:symmetry] Fine-tuning implies the constants are contingent and improbable. If constants are arbitrary, symmetries are accidental. If symmetries are fundamental, constants should be derivable. String theory predicts ~10^500 vacua. It predicts variation, not uniqueness. Loop quantum gravity does not yet predict constants. The tension is unresolved. Are physical laws necessary or contingent? Both cannot be fully right. [SOURCE:mandelbrot-1967|type:scale] [SOURCE:wilson-1971|type:renormalization]

## The Honest Limits

The anthropic principle is a selection effect, not an explanation. We observe fine-tuning because we could not exist otherwise. This is trivially true. It is predictively empty. The multiverse renders fine-tuning statistically expected: in 10^500 vacua, some permit life. We inhabit one of those. But the multiverse is unobserved. Wheeler "it from bit" is speculative. It carries no empirical content. A definitive falsification would require: a derivation of the constants from first principles with no free parameters; or direct empirical confirmation of a multiverse with varying constants; or demonstration that life is robust across orders-of-magnitude parameter variation. None of these exist. C24 stays at Tier T3. It is carried, not load-bearing.

Explanations on the table: multiverse plus observer selection. Most physicists prefer this. It is untestable. Dynamical selection: some parameter values are attractors of cosmological dynamics. Testable in principle. String theory landscape: 10^500 vacua. Consistent with multiverse. Fundamental principle: a yet-undiscovered principle determines the parameters uniquely. No candidate known. No explanation: the parameters are what they are. Intellectually permissible. Unsatisfying.

**Typed:** T3. **Status:** unexplained. Carried as open question. The anthropic principle does not explain the constants. It explains why you are here to ask. The explanation is still missing.
