1. Introduction
Classical general relativity predicts singularities — regions where spacetime curvature diverges and the theory breaks down. Attempts to quantize gravity have struggled to resolve this issue, as singularities appear to represent both infinite curvature and physical pathologies.
The Total Entropic Quantity (TEQ) framework offers a fundamentally different perspective. In TEQ, spacetime geometry is not fundamental, but emergent from an underlying entropy geometry defined on configuration space. The core object is the entropy-weighted action:
where
represents local entropy curvature. Path amplitudes are given by:
This resolution is not a technical regularization of general relativity, nor an artifact of a particular quantization scheme. Rather, it arises from a fundamental shift of perspective: in the TEQ framework, spacetime is not fundamental, but emergent from an underlying entropy geometry. The apparent singularities of classical spacetime are structurally replaced by boundaries of distinguishability — points where the entropy metric loses rank. From this viewpoint, the singularity problem dissolves not because the infinities are “tamed,” but because the very notion of spacetime divergence becomes inapplicable at resolution boundaries. This marks a profound correction to the inherited ontology of gravitational physics—not a technical adjustment, but a structural replacement.
In this paper, we prove that within TEQ:
Singular configurations are exponentially suppressed in the path integral.
Physical observables remain finite.
Most importantly, the entropy metric exhibits rank loss at classical singularities, corresponding to collapse of distinguishability, not physical divergence.
We explicitly demonstrate this in the Schwarzschild singularity, providing the first rigorous example of singularity resolution in TEQ.
2. Singularities in TEQ: Structural Principles
In TEQ, the emergent spacetime metric arises from the entropy metric
, defined on configuration space:
Entropy curvature
governs both the dynamics of resolution and the suppression of unstable configurations. The relation between entropy curvature and distinguishability is established explicitly in [
1], where the form of
and its role in defining resolution boundaries are rigorously derived. In regions where classical curvature diverges, entropy curvature likewise diverges, but this does not imply physical divergences.
Crucially, we show that the entropy metric undergoes strict rank loss in such regions. The apparent singularity is thus reinterpreted as a boundary of distinguishability — an entropy resolution boundary.
While the idea of interpreting singularities as loss of degrees of freedom has appeared in various forms (e.g., quantum geometry approaches [4,5,6,7]), TEQ provides a systematic and quantitative mechanism: rank loss arises from entropy curvature divergence within an explicitly weighted path integral. The entropy metric , derived from the effective action, is not imposed but computed from first principles. This structural derivation is unique to the TEQ framework as formulated here.
3. Explicit Example: Schwarzschild Singularity
Consider the Schwarzschild metric:
with
. The classical singularity occurs at
, where curvature scalars diverge.
In TEQ, configuration variables are
, and the entropy metric
determines local resolution. Near
, we analyze the scaling of
:
4. Suppression of Singular Paths
Entropy curvature diverges as
, leading to:
Singular configurations contribute zero weight to the path integral. Physical observables:
remain finite.
5. Conclusion
We have explicitly demonstrated that in TEQ:
Classical singularities correspond to strict rank loss in the entropy metric.
No physical divergence occurs.
The apparent singularity becomes a well-defined entropy resolution boundary — a collapse of distinguishability.
The TEQ formalism remains fully consistent and well-defined.
The result presented here exemplifies how a shift to an entropy-based structural framework, rather than an attempt to quantize a flawed spacetime ontology, can naturally resolve longstanding conceptual paradoxes. In TEQ, the singularity problem does not require a technical solution because it does not arise: resolution boundaries replace unphysical divergences.
While we explicitly demonstrated the mechanism for the Schwarzschild singularity, the result is not tied to this specific example. The entropy metric reflects local distinguishability, and the process of rank loss under divergent entropy curvature is generic. In cosmological singularities (e.g., big bang models), the proper volume elements collapse, producing the same degeneration of . For rotating black holes (Kerr), the angular momentum introduces additional off-diagonal structure, but again, the distinguishability structure in collapsing regions reduces to lower-dimensional forms, leading to rank loss. A systematic treatment of these cases is underway.
Beyond this structural resolution, the operational implications of entropy rank loss merit further exploration. In particular, the suppression of entropy-weighted path contributions near gravitational boundaries may lead to testable signatures in high-curvature regimes, or in deviations from classical predictions for quantum-gravitational modes. Investigating such measurable effects represents an important direction for future work.
In this precise sense, we may say: the universe has no singularities—only limits of distinguishability.
