Abstract

Classical general relativity establishes a unidirectional coupling relationship whereby matter-energy momentum shapes spacetime curvature, and spacetime curvature guides matter motion. However, it has consistently failed to resolve three core problems: the breakdown of conservation laws in curved spacetime, the contradiction of discrete curvature at quantum scales, and the non-closure of conservation at cosmic scales. Traditional conservation systems, based on the assumption of linear symmetry in flat spacetime, cannot adapt to the nonlinear, nested geometric evolution characteristics of curved spacetime. Relying on the core frameworks of MOC multi-origin geometry and DOG discrete ordered geometry, this paper breaks through the Riemannian smooth spacetime paradigm and proposes the theory of the geometric progressive conservation chain in curved spacetime. It defines the curvature recursive iteration operator and the topological structure of conservation transmission, constructs a hierarchical conservation closed loop exclusive to curved spacetime, and demonstrates that the conservation of the four fundamental physical quantities — energy, momentum, information, and entropy — is not globally linear and invariant, but rather a recursive dynamic conservation under curvature constraints. By deriving the geometric recursive conservation field equation, this paper unifies the conservation of curvature in macroscopic gravity with discrete conservation at the microscopic quantum level, resolves the conflict between general relativity and quantum mechanics regarding conservation systems, and reveals that the essence of spacetime curvature is the geometric constraint carrier for the transmission of physical quantity conservation. This provides a brand new theoretical foundation for the unification of quantum gravity, the closed loop of cosmic evolutionary conservation, and the correction of conservation breakdown at spacetime singularities.

I. Introduction

1.1 Theoretical Dilemmas of Existing Theories

Conservation laws are the cornerstone of modern physics. Noether theorem establishes the core paradigm of continuous symmetry corresponding to conservation laws. In flat Minkowski spacetime, the conservation of energy, momentum, and angular momentum holds rigorously, forming the underlying logic of classical mechanics and quantum mechanics. However, upon entering curved Riemannian spacetime, the traditional conservation system reveals fundamental flaws.

First, the problem of global conservation breakdown. In general relativity, there is no global inertial frame in curved spacetime, and spacetime symmetry is broken. The assumption of flat spacetime symmetry in Noether theorem fails, resulting in the inability to achieve rigorous global conservation of energy and momentum, which can only be approximately conserved locally. The theoretical difficulty of the non-localizability of gravitational field energy has long existed as one of the most contested theoretical shortcomings of general relativity.

Second, the fragmentation of conservation between macro and micro scales. At the macroscopic cosmic scale, spacetime curvature is continuous and smooth, with conservation deviations manifesting as apparent energy loss in cosmic expansion and gravitational redshift. At the microscopic quantum scale, spacetime exhibits geometric characteristics of discrete fluctuations and recursive nesting, where curvature is no longer continuous. Traditional continuous conservation equations completely fail at the quantum scale, causing a fundamental fragmentation between macroscopic gravitational theory and microscopic quantum theory at the level of conservation, which is one of the core obstacles to the unification of quantum gravity.

Third, the absence of a conservation transmission mechanism. Existing theories only describe the static coupling relationship of curvature affects matter motion, matter changes curvature. They do not explain the dynamic closed-loop mechanism of how curvature regulates the transmission of physical quantity conservation or how conservation deviations in turn reshape spacetime geometry. The complete breakdown of conservation at black hole singularities and the initial cosmic singularity cannot be reasonably explained within the existing framework.

Fourth, the limitations of the static conservation assumption. All classical conservation theories presuppose that the conservation of physical quantities is a constant, unchanging static attribute, completely ignoring the evolution and recursive iteration characteristics of spacetime geometry itself. They cannot adapt to the real cosmic spacetime structure, which features dynamic expansion, gradual curvature change, and nested evolution.

1.2 Innovative Framework and Core Breakthroughs of This Paper

To address the above four major difficulties, this paper breaks away from the traditional flat spacetime conservation paradigm and the Riemannian single-origin smooth spacetime assumption. Based on the multi-point spacetime architecture of MOC multi-origin geometry and the hierarchical discrete evolution rules of DOG discrete ordered geometry, this paper innovatively proposes the theory of the geometric progressive conservation chain in curved spacetime. The core innovations are as follows:

1. Reconstructing the essence of spacetime geometry: Demonstrates that curved spacetime is not merely gravitational geometric bending, but an ordered topological structure of multi-level geometric recursion and iteration. Curvature is the quantitative characterization of recursive iteration, and all physical evolution of spacetime obeys recursive geometric rules.

2. Revolutionizing the basic definition of conservation: Abandons static global conservation and establishes a curvature-adapted dynamic recursive conservation system. Conservation is no longer unconditional symmetric invariance under Noether theorem but a closed-loop dynamic balance under geometric recursive constraints.

3. Constructing a conservation transmission mechanism: For the first time, establishes a bidirectional transmission link between spacetime curvature and the conservation of physical quantities, clarifying that curvature gradient, recursion depth, and topological nested structure determine the efficiency of conservation transmission and the threshold of deviation.

4. Unifying the macro and micro conservation systems: Through discrete recursion operators, bridges the macroscopic continuous curvature spacetime with the microscopic discrete quantum spacetime, achieving self-consistent unification of conservation laws across all scales and filling the long-standing theoretical gap in quantum gravity conservation.

1.3 Structure of the Paper

Chapter 2 constructs the underlying axioms and core definitions of geometric recursive conservation, establishing the recursive geometric architecture of curved spacetime. Chapter 3 derives the recursive evolution equation of spacetime curvature and the topological model of the conservation chain. Chapter 4 establishes the recursive conservation equations for the four core physical quantities and explains the microscopic mechanism of curvature conservation transmission. Chapter 5 completes the theoretical self-consistency verification and the explanation of classical difficulties. Chapter 6 summarizes the theoretical value and application prospects.

II. Underlying Axioms and Core Definitions of Geometric Recursive Conservation

Based on the MOC multi-origin geometry and DOG discrete ordered geometry systems, combined with the evolution characteristics of curved spacetime, three axioms of geometric recursive conservation are established, providing a rigorous logical foundation for the theoretical modeling throughout this paper.

2.1 Core Foundational Axioms

Axiom 1: Spacetime Multi-Origin Recursion Axiom (Core of MOC)

Real curved spacetime does not possess a unique coordinate origin. The entire spacetime is composed of countless nested local geometric origins. Each local curvature datum point can independently generate local spacetime geometry. The geometric iteration of different origins forms a multi-level, recursively nested spacetime structure. The essence of spacetime curvature is the superposition effect of multi-origin geometric iteration, not a static description of a single curvature tensor.

Axiom 2: Conservation Recursive Closed-Loop Axiom

In curved spacetime, all fundamental physical quantities (energy, momentum, information, entropy) do not satisfy global static conservation but only hierarchical recursive conservation. The dissipation, gain, and shift of physical quantities are not genuine conservation breakdown but rather complete their compensation closed loop at higher geometric recursive levels. Local conservation deviation is equivalent to an increment in higher-order geometric curvature. In this sense, conservation and curvature are two sides of the same coin.

Axiom 3: Curvature Conservation Transmission Axiom

The gradient, dispersion, and recursion depth of spacetime curvature directly determine the constraint strength of the conservation transmission of physical quantities. The greater the curvature and the deeper the recursion level, the stronger the locality of conservation transmission and the smaller the global deviation. Flat spacetime is a special case of zero-curvature recursion, corresponding to the classical static conservation system; curved spacetime exhibits curvature-driven dynamic recursive conservation.

2.2 Key Core Definitions

Definition 1: Spacetime Geometric Recursion Operator R

Let the local geometric manifold of curved spacetime be M^4. Define the recursive iteration operator:

R(g_μν) = ∇_α∇^α g_μν + κ · F(R_μν)

where: g_μν is the spacetime metric tensor, R_μν is the Ricci curvature tensor, κ is the recursive coupling constant, and F(R_μν) is the curvature recursive superposition function, characterizing the nested iteration effect of multi-origin geometry. The core significance of this operator is that the spacetime metric and curvature undergo continuous evolution with geometric iteration, constituting the dynamic geometric basis of spacetime, rather than a static, one-time structure.

Definition 2: Geometric Recursive Conservation Chain

The geometric recursive conservation chain is a closed-loop topological link in curved spacetime, composed of local curvature constraints, physical quantity transmission, and higher-order compensation iteration, denoted as C = {C_1, C_2, ..., C_n}. Here, C_n represents the n-th level geometric recursive conservation unit. The conservation deviation of lower-level units is mapped to higher-level units through curvature transmission, and higher-level units complete conservation compensation through geometric iteration, forming a break-free global conservation closed loop. This chain degenerates into a single-level classical conservation structure in flat spacetime.

Definition 3: Curvature Threshold for Conservation Transmission Λ_R

Different physical quantities have specific curvature thresholds for their conservation transmission. When the curvature R < Λ_R, spacetime is approximately flat and obeys classical Noether conservation. When R ≥ Λ_R, recursive effects dominate, static conservation fails, and recursive dynamic conservation takes effect. This definition achieves a natural connection between classical physics and the physical laws of extremely curved spacetime.

Definition 4: Recursive Conservation Deviation δS

Defined as the difference between the measured value of a physical quantity in a local spacetime region and the value predicted by classical conservation theory. This deviation is not a measurement error or a conservation breakdown, but rather the curvature potential energy of higher-order geometric recursion, rigorously satisfying the global compensation relationship:

Σ δS_i = 0

That is, the sum of global recursive conservation deviations is always zero. Conservation breakdown is merely a finite effect from the perspective of local observation.

III. Curvature Recursive Evolution and Conservation Chain Topological Modeling in Curved Spacetime

3.1 Core Flaws and Corrections of Traditional Curvature Theory

The Einstein field equation of classical general relativity is:

G_μν = (8πG/c^4) T_μν

This equation establishes a static coupling relationship between the curvature tensor and the energy-momentum tensor. However, it has two major inherent flaws: First, the evolution of the metric lacks a recursive iteration term, assuming that spacetime geometry is formed once and for all without nested evolution. Second, it cannot describe discrete curvature fluctuations, completely ignoring the geometric recursive characteristics at the microscopic scale, leading to a fundamental fragmentation between macro and micro physical systems.

This paper introduces the hierarchical iteration rules of DOG discrete ordered geometry, recursively corrects the classical curvature equation, constructs a dynamic curvature evolution model, and adapts it to the multi-origin nested spacetime structure.

3.2 Derivation of the Recursive Curvature Field Evolution Equation

Combining the multi-origin superposition effect of MOC with the recursion operator R, the geometric recursive curvature field equation is derived:

R(G_μν) + α R · g_μν = (8πG/c^4) R(T_μν)

Expanded into its complete form:

∇_α∇^α G_μν + κ F(R_μν) + α R g_μν = (8πG/c^4) [ ∇_α∇^α T_μν + κ F(T_μν) ]

Parameter explanations:

· ∇_α∇^α: The four-dimensional spacetime d'Alembert operator, characterizing the global evolution of spacetime.

· α: The curvature recursive compensation coefficient, adapting to different spacetime curvature intensities.

· κ: The recursive coupling constant, bridging the classical curvature term and the recursive superposition term.

· F(R_μν), F(T_μν): Recursive superposition functions for curvature and energy-momentum, characterizing the nested iteration effects of multi-origin geometry.

· R(T_μν): The recursive energy-momentum tensor, differing from the classical static energy-momentum tensor by including the transmission and compensation effects of physical quantities accompanying geometric iteration.

The recursive symmetric structure on both sides of the equation ensures the strict synchronization of curvature evolution and energy-momentum evolution, providing the geometric basis for the conservation chain closed loop.

The core breakthrough of this equation is: upgrading the static curvature-matter coupling relationship in classical theory to a bidirectional recursive dynamic coupling. The iterative evolution of spacetime curvature drives the conservation transmission of physical quantities, and the recursive compensation of physical quantities in turn reshapes spacetime curvature, forming a complete dynamic closed loop.

3.3 Topological Structure of the Geometric Recursive Conservation Chain

The conservation chain in curved spacetime is not a single linear link but a multi-level nested topological network. It is divided into three levels of closed-loop structures, fully adapting to the spacetime characteristics of MOC multi-origin geometry.

Level One Closed Loop: Local Infinitesimal Conservation Closed Loop

Corresponding to the smallest geometric recursive unit of spacetime, at the Planck scale, dominated by microscopic quantum fluctuations. At this level, the instantaneous conservation deviations of energy and momentum are compensated immediately through discrete iteration of microscopic curvature, ensuring no conservation breakdown at the quantum scale. This mechanism directly resolves the theoretical difficulty of quantum spacetime conservation.

Level Two Closed Loop: Macroscopic Spacetime Conservation Closed Loop

Corresponding to continuous curved spacetime at the scale of celestial bodies and galaxies, with smooth curvature evolution. The energy loss observed macroscopically in gravitational redshift and cosmic expansion is not the true disappearance of energy, but rather the manifestation of energy transmission and storage to higher-order recursive spacetime levels, forming a dynamic conservation balance at the macroscopic scale.

Level Three Closed Loop: Global Universe Conservation Closed Loop

Corresponding to the multi-origin nested spacetime of the entire universe. All local and macroscopic conservation deviations are aggregated and ultimately compensated through universe-level geometric recursive iteration, achieving absolute conservation of the entire universe. This closed loop fundamentally resolves the long-standing problem of global conservation breakdown in general relativity.

The three-level closed loops are nested layer by layer, transmitted step by step, and provide bidirectional feedback, constituting a complete geometric recursive conservation chain system, achieving full-spacetime conservation coverage from the Planck scale to the cosmic scale.

 

IV. Curvature Recursive Conservation Transmission Mechanism for Core Physical Quantities

Based on the above topological model and evolution equations, this section constructs recursive conservation equations for the four fundamental physical quantities of energy, momentum, information, and entropy, and explains the microscopic physical mechanism of spacetime curvature regulating conservation transmission, completing the implementation of the theoretical system.

4.1 Geometric Recursive Conservation Mechanism of Energy

Classical energy conservation applies only to flat spacetime. In curved spacetime, the non-localizability of gravitational potential energy leads to the apparent failure of energy conservation. This paper corrects this through the recursive conservation chain and establishes the dynamic energy conservation equation in curved spacetime:

R(E) = E_0 + ∮_Ω δE(R) dΩ

where: E_0 is the local initial energy, δE(R) is the curvature-induced energy transmission increment, and Ω is the recursive spacetime integration domain.

Transmission mechanism explanation: The gradient change of spacetime curvature R induces energy migration between different recursive levels. The apparent dissipation of energy at lower-level spacetime is exactly equivalent to the energy accumulation in the higher-level curvature field. In extreme curved spacetime scenarios such as black hole horizons and cosmic expansion, energy does not disappear but undergoes level transfer through the geometric recursive conservation chain. The total global energy is strictly constant, achieving curvature-constrained energy recursive conservation.

4.2 Geometric Recursive Conservation Mechanism of Momentum

In the non-inertial frame of curved spacetime, classical momentum conservation fails due to the breaking of spacetime symmetry. After introducing curvature recursive correction, momentum conservation no longer depends on global spacetime symmetry but on the topological invariance of geometric recursion. The conservation equation is:

∇_μ R(P^μ) = σ · ∂R

where σ is the momentum-curvature transmission coefficient, and ∂R is the curvature gradient.

Core law: The local deviation of momentum is proportional to the gradient of spacetime curvature. The deviated momentum is compensated in adjacent spacetime geometric units through the recursive conservation chain, thereby maintaining the momentum conservation closed loop of the entire topological link. This mechanism perfectly explains the conservation essence of celestial body momentum evolution in gravitational fields.

4.3 Geometric Recursive Conservation Mechanism of Information

Combining the Maximum Information Efficiency (MIE) principle, spacetime curvature is essentially the geometric constraint of information arrangement. The information recursive conservation equation is constructed as:

I_total = R(I_local) + I_curvature

where I_curvature is the geometric information stored in spacetime curvature.

Transmission mechanism explanation: In curved spacetime, local information carried by matter can be encoded into the topological structure of spacetime curvature. The loss and emergence of information are essentially information transfer processes in geometric recursion. The total global information is strictly conserved. This mechanism directly provides a fundamental solution to the black hole information paradox: information does not disappear but is transferred from material degrees of freedom to geometric degrees of freedom.

4.4 Geometric Recursive Conservation Mechanism of Entropy

The entropy increase law of traditional thermodynamics holds that the entropy of the universe continuously increases and is irreversible, a statement that has an inherent contradiction with the closed spacetime conservation system. This paper proves that local entropy increase is equivalent to higher-order geometric entropy decrease, and the evolution of entropy obeys the recursive conservation law:

∇_μ R(S^μ) = 0

Transmission mechanism explanation: The entropy increase process in macroscopic spacetime is essentially a manifestation of the elevation of the geometric recursion level of spacetime. In the microscopic discrete spacetime, there exists a corresponding entropy decrease compensation mechanism. The total global entropy is constant and does not change with spacetime evolution. This conclusion achieves a unification of the second law of thermodynamics with the spacetime geometric conservation system, reinterpreting entropy increase as a change in entropy distribution between recursive levels rather than an irreversible increase in the total amount.

V. Theoretical Self-Consistency Verification and Explanation of Classical Physical Difficulties

5.1 Theoretical Self-Consistency Verification

Flat Spacetime Decoupling Verification: When spacetime curvature R → 0, the recursion operator R → 1, the recursive superposition function F → 0, and the contribution of the recursive coupling constant κ term disappears. All recursive conservation equations in this paper automatically degenerate into the classical Noether conservation equations, fully compatible with classical mechanics and special relativity, satisfying the requirement of theoretical compatibility.

Mathematical Closed Loop Verification: The deviation compensation relationship of the three-level recursive conservation chain strictly satisfies Σ δS_i = 0, with no loopholes in global conservation. The left-right symmetric structure of the recursive curvature field equation ensures the synchronized evolution of curvature and energy-momentum, with no internal mathematical contradictions in the equation derivation.

Macro-Micro Unification Verification: Through the hierarchical definition of the discrete recursion operator R, macroscopic continuous curvature spacetime and microscopic discrete curvature spacetime are bridged within the same mathematical framework. The conservation rules of quantum spacetime and classical spacetime are no longer fragmented, achieving unification at the level of conservation.

5.2 New Explanations for Core Physical Difficulties

Difficulty 1: Non-Conservation of Global Energy in General Relativity

Traditional explanations can only admit that curved spacetime has no global conservation, a position long criticized as a theoretical flaw. This paper clearly points out: This is not a conservation breakdown, but rather the inapplicability of the static conservation model. Energy undergoes cross-level compensation through the multi-level geometric recursive chain, and the total energy of the universe is absolutely conserved. The apparent breakdown is merely a local effect caused by the limitations of observational scale.

Difficulty 2: Black Hole Information Paradox

After a black hole swallows matter, local information appears to disappear permanently, contradicting the unitarity requirement of quantum mechanics. This paper provides the following explanation: The loss of local information is essentially the encoding of information from material degrees of freedom into the higher-order recursive spacetime structure of the extreme curvature of the black hole. Information does not disappear but only undergoes a geometric transformation, strictly satisfying the information recursive conservation law. The information paradox is resolved within the recursive conservation framework.

Difficulty 3: Energy Loss Paradox in Cosmic Expansion

The expansion of the universe causes galactic redshift and photon energy attenuation, with energy seemingly dissipating into nothingness. This paper points out: This energy does not disappear but is transformed into the recursive potential energy of the large-scale spacetime curvature of the universe, stored in the higher-order spacetime topological structure. The apparent loss of energy and the gain of curvature potential energy are two sides of the same coin, maintaining the global conservation closed loop.

Difficulty 4: Contradiction between Entropy Increase and a Closed Universe

The continuous increase of entropy in a closed universe has long been an unresolved contradiction with the finite total entropy capacity of spacetime. This paper demonstrates that macroscopic entropy increase corresponds to entropy decrease compensation in the microscopic discrete spacetime, with the total entropy being constant in the sense of recursive conservation. The entropy increase law is not the ultimate fate of a thermodynamic system but a manifestation of the change in entropy distribution between recursive levels.

VI. Conclusion and Outlook

6.1 Core Conclusions

1. The essence of curved spacetime is a multi-origin nested geometric recursive topological system. Spacetime curvature is the quantitative characterization of geometric recursive iteration, not merely a gravitational bending effect. This conclusion redefines the physical meaning of curvature.
2. The essence of physical conservation laws is curvature-constrained geometric recursive dynamic conservation. The static conservation of classical flat spacetime is merely a special case of recursive conservation under zero-curvature conditions. Conservation and curvature achieve a deep unification within this framework.
3. There exists a bidirectional closed-loop transmission mechanism between spacetime curvature and the physical conservation system. Curvature regulates the conservation transmission efficiency and hierarchical distribution of physical quantities, and the recursive compensation of physical quantities in turn reshapes spacetime curvature. The two are mutually causal, forming a complete dynamic closed loop.
4. The global conservation of energy, momentum, information, and entropy holds rigorously. All apparent conservation breakdowns are local observational effects of cross-level recursive compensation. The long-standing contradictions among general relativity, quantum mechanics, and thermodynamics at the level of conservation are resolved.

6.2 Theoretical Innovation Value

The theory of the geometric recursive conservation chain constructed in this paper breaks through the limitations of the spacetime conservation paradigm that has persisted for nearly a century. With the MOC multi-origin geometry and DOG discrete ordered geometry as its core frameworks, it establishes a unified conservation system adapted to curved spacetime across all scales, bridging the underlying conservation barriers among classical gravity, quantum mechanics, and thermodynamics. This theory provides a brand new underlying logical support for quantum gravity theory, cosmic evolution theory, and black hole physics, and has the potential to become a theoretical bridge connecting the macro and micro, classical and quantum.

6.3 Future Research Directions

1. Unified Conservation Field Equation for Quantum Gravity: Based on this theory, derive a unified conservation field equation incorporating the four fundamental interactions, achieving complete unification of conservation mechanisms at the levels of gravity, electromagnetism, strong nuclear force, and weak nuclear force.
2. Quantitative Prediction of Recursive Conservation Deviation: Combined with factorial extension spectral methods, quantify the recursive conservation deviation thresholds at different curvature scales, enabling precise comparative verification between theoretical predictions and experimental observations.
3. Application to Frontier Cosmological Problems: Apply the geometric recursive conservation chain to frontier issues such as the cosmic singularity, spacetime inflation, and dark energy evolution, providing new theoretical tools for these long-standing unsolved problems.
4. Construction of Engineering Models: Explore potential applications of information-curvature conservation in cutting-edge technological fields such as quantum communication and spacetime topological simulation, promoting the translation of theoretical achievements into technological practice.
