Towards a Unified Cyclic Cosmology:

Embedding Spacetime Ladder Dynamics

in AdS/CFT/dS Holographic Framework

迈向统一的循环宇宙学：将时空阶梯动力学嵌入AdS/CFT/dS全息框架中

Date: September 3, 2025

Abstract

We propose a comprehensive cosmological framework that unifies the Spacetime Ladder Theory (STLT) with the mathematical rigor of AdS/CFT/dS holographic duality. The theory posits that the cosmic origin is a dark matter ground state—a conformally invariant gauge field composed of energy field (E) and qi-field (Q). Its polarization drives cosmic evolution: the energy field contracts via logarithmic spirals (AdS phase), generating ordinary matter through Hawking-Page-like phase transitions; the qi-field expands (dS phase), yielding dark energy through conformal symmetry breaking. These phases couple through polarization scalar field Ω in the boundary CFT, enabling a cyclic universe without initial singularities. This framework unifies dark matter, dark energy, and fundamental forces while explaining galactic rotation curves, Pioneer anomaly, and Hubble tension. It predicts testable phenomena including CMB topological defects and hostless high-energy events, verifiable by CMB-S4, JWST, and Euclid.

摘要 我们提出了一个全面的宇宙学框架，将时空阶梯理论 (STLT) 与 AdS/CFT/dS 全息对偶的数学严谨性统一起来。该理论认为宇宙起源于暗物质基态——一个由能量场 (E) 和气场 (Q) 组成的共形不变规范场。其极化驱动着宇宙演化：能量场通过对数螺旋收缩（AdS 相），通过类似霍金-佩奇相变产生普通物质；气场膨胀（dS 相），通过共形对称性破缺产生暗能量。这些相通过边界 CFT 中的极化标量场 Ω 耦合，从而实现一个没有初始奇点的循环宇宙。该框架统一了暗物质、暗能量和基本力，同时解释了星系自转曲线、先驱者异常和哈勃张力。它预测了可测试的现象，包括 CMB 拓扑缺陷和无主高能事件，可通过 CMB-S4、JWST 和 Euclid 验证。

1. Introduction

The ΛCDM cosmological model, while remarkably successful, faces profound unresolved puzzles:

• Initial singularity problem: The Big Bang origin represents a boundary where known physics breaks down
• Dark components: Dark matter (26.8%) and dark energy (68.3%) lack fundamental microscopic explanation
• Coupling problem: Matter, dark matter, and dark energy are treated as independent without unified origin
• Cosmic fate: The model leads inevitably to heat death without physically motivated cyclic mechanism

The Spacetime Ladder Theory (STLT) offers a radical alternative: the primordial cosmic substrate is a unified dark matter field characterized as an energy-qi (E-Q) gauge field. Cosmic evolution is driven by field polarization, simultaneously generating contracting states (ordinary matter) and expanding states (dark energy), inherently avoiding initial singularity and suggesting cyclic cosmology.

This work bridges STLT's physical intuition with the mathematical rigor of AdS/CFT correspondence, constructing a "Polarization-Holographic" cyclic cosmology where:

• AdS phase corresponds to energy field (E) contraction
• dS phase corresponds to qi-field (Q) expansion
• Boundary CFT provides coupling machinery via polarization field Ω

2. Theoretical Framework: STLT and Holographic Duality

2.1 Dark Matter Ground State: Conformal Gauge Field

The fundamental entity is a conformally invariant non-Abelian gauge field with dynamics governed by:

$$S^{\text{dark}}=-\genfrac{}{}{0ex}{}{1}{4g^2}\int d^{4}x\sqrt{-g}\text{Tr}(F^{\mu \nu }{F}^{\mu \nu })-\genfrac{}{}{0ex}{}{1}{2}\int d^{4}x\sqrt{-g}{m}^{\text{pol}}(\Omega )\text{Tr}(A^{\mu }{A}^{\mu })$$

where $F^{\mu \nu }={\nabla }^{\mu }{A}^{\nu }-{\nabla }^{\nu }{A}^{\mu }+[A^{\mu },A^{\nu }]$ and $m^{\text{pol}}(\Omega )$ is polarization-induced mass from scalar field Ω condensation.

Enhanced Mathematical Foundation:

The gauge group is specified as $SU(N)\times U(1)$, where $SU(N)$ describes dark matter's non-Abelian degrees of freedom corresponding to higher-dimensional topology, and $U(1)$ corresponds to electromagnetic-like energy-qi coupling.

The polarization mass arises from Higgs-like mechanism:

$$V(\Omega )={\mu }^2{\Omega }^2+\lambda {\Omega }^4$$

with ${\mu }^2<0$ triggering spontaneous symmetry breaking and $\lambda >0$ ensuring stability. The polarization mass is:

$$m^{\text{pol}}(\Omega )=\xi ⟨\Omega {⟩}^2$$

2.2 Holographic Dictionary: Wave Function-Partition Function Duality

Core Postulate A: The dS wave function equals CFT partition function:

$${\Psi }^{dS}[{?}^0]=Z^{\text{CFT}}[{?}^0]\text{with }{R}^{AdS}\to i{R}^{dS},t^E\to it$$

This transforms dS future infinity $I^{+}$ late-time correlations into boundary CFT source insertion problems, achieving computable AdS contraction → dS expansion transitions.

Mass-Dimension Mapping (Analytic Continuation):

$$\Delta (\Delta -d)=m^2{R}^{AdS}\Rightarrow \Delta =\genfrac{}{}{0ex}{}{d}{2}\pm i\nu$$

for dS, allowing complex weights supporting STLT's polarization/resonance-induced oscillations.

2.3 STLT Polarization Field as Boundary Driver

The polarization field Ω is elevated to boundary operator $O^{\Omega }$ double-trace deformation:

$$S^{\text{CFT}}\to S^{\text{CFT}}+\int d^{d}x\left[{\lambda }^1{O}^{\Omega }+\genfrac{}{}{0ex}{}{f}{2}{O}^{\Omega }+?\right]$$

The β-functions control ${\Lambda }^{\text{eff}}$ running and cyclic fixed points, embedding STLT's ${\Lambda }^{\text{eff}}=\kappa ({\rho }^m-{\rho }^{de})$ into computable RG/holographic dictionary.

2.4 Bulk-Boundary Action System

Complete Bulk Action:

$$S^{\text{bulk}}=\int d^{d+1}x\sqrt{-g}\left[\genfrac{}{}{0ex}{}{1}{16\pi G}(R-2{\Lambda }^0)-\genfrac{}{}{0ex}{}{1}{4g^2}\text{Tr}{F}^2-\genfrac{}{}{0ex}{}{1}{2}(\nabla \Omega {)}^2-V(\Omega )-\genfrac{}{}{0ex}{}{\xi }{2}{\Omega }^{2}R\right]$$

The $\xi {\Omega }^{2}R$ term (bulk) plus $O^{\Omega }$ (boundary) jointly induce polarization mass, avoiding arbitrary mass insertion while maintaining gauge theory origin.

2.5 Phase Transitions and Cosmic Evolution

2.5.1 AdS Phase: Contraction and Matter Genesis

Energy field contraction follows logarithmic spiral collapse in AdS background:

$$r(\theta )=r^0{e}^{-k\theta }$$

At critical polarization $⟨\Omega ⟩={\Omega }^c$, a Hawking-Page phase transition occurs. In bulk AdS, this corresponds to black hole formation; holographically, it's deconfinement transition generating massive gauge bosons (fundamental force mediators) while condensed states become ordinary particles.

2.5.2 dS Phase: Expansion and Dark Energy

Qi-field expansion enters de Sitter phase:

$$d{s}^2=-d{t}^2+e^{2Ht}(d{r}^2+r^{2}d{\Omega }^2),H=\sqrt{\genfrac{}{}{0ex}{}{{\Lambda }^{\text{eff}}}{3}}$$

corresponding to STLT's qi-field logarithmic expansion $r=r^0{e}^{kt}$.

2.5.3 CFT Phase: Conformal Bridge

Polarization field Ω dynamics:

$$\square \Omega +\genfrac{}{}{0ex}{}{\partial V(\Omega )}{\partial \Omega }=\text{source}$$

The holographic correspondence $Z^{\text{grav}}=⟨e^{\int {?}^0\mathcal{O}}{⟩}^{\text{CFT}}$ ensures continuous AdS-dS transitions.

3. Cyclic Cosmology and Dynamic Cosmological Constant

3.1 Holographic RG Flow Description

Cosmic cycles are described as holographic renormalization group flow. Polarization field evolution corresponds to UV (AdS) → IR (dS) flow and vice versa. Cycle "bounces" correspond to periodic fixed points:

$$\genfrac{}{}{0ex}{}{d{\lambda }^1}{d\ln \mu }={\beta }^1({\lambda }^1,f,\dots ),\genfrac{}{}{0ex}{}{df}{d\ln \mu }={\beta }^f(f,\dots )$$ $$\Rightarrow \genfrac{}{}{0ex}{}{d{\Lambda }^{\text{eff}}}{d\ln \mu }=F({\beta }^1,{\beta }^f,\dots )$$

Cyclic bounce = neutralization point (${\rho }^m\approx {\rho }^{de}\Rightarrow {\Lambda }^{\text{eff}}\to 0$) becomes RG fixed point: ${\beta }^1={\beta }^f=0$.

3.2 Topological Transitions

Each cycle involves topological changes:

• AdS phase: simply connected sphere topology (${\pi }^1=0$)
• dS phase: nontrivial fundamental group (torus-like, ${\pi }^1?=0$)

Transitions are driven by polarization source terms:

$${\Pi }^a={\partial }^a\Omega +\text{topological term}$$

3.3 Complexity as Cosmic Clock

dS static patch complexity exhibits long-term linear growth:

$$C^{dS}(t)\sim {\text{Vol}}^{\text{ext}}[{\Sigma }^t]\Rightarrow \dot{C}>0$$

serving as geometric measure of cyclic phases/arrow, naturally aligning with STLT's "expansion phase."

4. Force Unification and Dimensional Hierarchy

4.1 Gauge Group Breaking

Four fundamental forces emerge from $SU(N)\times U(1)$ gauge group breaking under different dimensional projections:

• Gravity: AdS phase, low-dimensional curvature projection
• Electromagnetic: 6D qi-spacetime, $U(1)$ gauge field breaking
• Weak force: 18D shen-spacetime, $SU(2)$ gauge field breaking
• Strong force: 54D xu-spacetime, $SU(3)$ gauge field breaking

4.2 Unified Force Law

The modified force law in STLT:

$$F=m(E+v\times Q)$$

where $E$ and $Q$ correspond to different force strengths under dimensional projections.

---

5. Phenomenological Predictions and Explanations

5.1 Galactic Rotation Curves

The velocity-dependent qi-field component provides additional centripetal force:

$$F=m(-\nabla {\Phi }^N+v\times Q)$$

where $|Q|\sim c/R$ for galactic radius R, predicting flat rotation curves (v ~ 220-235 km/s) without particulate dark matter halos.

5.2 Pioneer Anomaly

Local qi-field strength generates anomalous acceleration:

$$a^{\text{anom}}=|v\times Q|\approx c{H}^0\approx 8.7\times 10^{-10}{\text{ m/s}}^2$$

matching observed $(8.74\pm 1.33)\times 10^{-10}$ m/s².

5.3 Hubble Tension

The tension arises from dimensional hierarchy: CMB probes 54D spacetime while local measurements probe 162D spacetime. Different effective gravitational constants in these projections create the observed $H^0$ discrepancy.

6. Testable Predictions and Observational Signatures

6.1 CMB Topological Defects

Symmetry breaking predicts cosmic strings and domain walls, leaving B-mode polarization vortices detectable by CMB-S4. Using four-point correlation functions:

$$⟨\mathcal{O}(x^1)\mathcal{O}(x^2)\mathcal{O}(x^3)\mathcal{O}(x^4)⟩$$

6.2 Hostless High-Energy Events

Ultra-high-energy cosmic rays and γ-ray bursts from polarization transitions or high-dimensional brane collisions lack identifiable host galaxies, testable through Fermi-LAT and Pierre Auger Observatory statistical analysis.

6.3 Dynamic Dark Energy

Specific equation of state evolution:

$$w(z)=-1+\alpha \genfrac{}{}{0ex}{}{\ln (1+z)}{1+z}$$

where α is small parameter, potentially detectable by Euclid and Nancy Grace Roman Space Telescope.

7. Consistency with Established Physics

7.1 Reduction to General Relativity

When polarization field freezes ($\Omega \to 1$) and mass term vanishes ($m^{\text{pol}}\to 0$), the theory reduces to standard GR with cosmological constant.

7.2 Quantum Field Theory Limit

Matter sector reduces to conventional Dirac and Klein-Gordon equations in appropriate limits.

7.3 Holographic Dictionary Preservation

The correspondence $Z^{\text{grav}}=⟨e^{\int {?}^{0}O}{⟩}^{\text{CFT}}$ is preserved, ensuring consistency with AdS/CFT realization of string theory.

---

8. Advanced Mathematical Framework

8.1 Cosmological Bootstrap

Physical principles (analyticity, unitarity, locality, symmetry) directly constrain late-time correlations. The "correlation-wave function" duality provides computable shape space for non-Gaussianities.

8.2 Celestial Holography

Mellin/radial transforms on superhyperboloidal slices define celestial correlations, connecting flat-space scattering with CFT structure constants for UHECR/GRB angular distributions.

8.3 Entanglement and Islands

dS geometry uses extremal surfaces/islands for information flow quantification, defining quantitative indicators for "cyclic heat death avoidance."

---

9. Future Experimental Tests

9.1 CMB-S4 Pipeline

Four-point functions and triangular configuration bootstrap scanning for resonance-type signatures.

9.2 Euclid/Roman Observatory

Joint fitting of $w(z)$ with deformation parameters using holographic priors.

9.3 Fermi-LAT/Auger Analysis

Extreme event celestial spectra using celestial transforms for shape learning.

10. Conclusion and Outlook

We have constructed a comprehensive cosmological model synthesizing STLT's physical insights with AdS/CFT/dS holographic duality's mathematical power. This framework provides first-principles origins for dark matter, dark energy, ordinary matter, and fundamental forces within a unified cyclic history, offering parsimonious explanations for key observational anomalies and clear testable predictions.

The upcoming precision observatories (CMB-S4, JWST, Euclid) will critically test this paradigm. If predictions are verified, this synthesis could mark a new chapter in fundamental physics, moving beyond ΛCDM toward truly unified cyclic cosmology.

Mathematical Appendix

A.1 Conformal Compactification and Boundary Structure

The cosmic ground state employs conformal compactification:

$$g^{\mu \nu }\to {\Omega }^2{g}^{\mu \nu },\Omega =⟨O{⟩}^{\text{CFT}}$$

A.2 Holographic Renormalization

Boundary stress-energy tensor:

$$T^{\mu \nu }=\genfrac{}{}{0ex}{}{2}{\sqrt{-g}}\genfrac{}{}{0ex}{}{\delta S^{\text{ren}}}{\delta g^{\mu \nu }}$$

Generalized Einstein equation:

$$G^{\mu \nu }+{\Lambda }^{\text{eff}}{g}^{\mu \nu }=8\pi G(T^{\mu \nu }+T^{\mu \nu }+T^{\mu \nu }+T^{\mu \nu })$$

A.3 Higher-Dimensional Manifold Structure

STLT's multi-dimensional hierarchy:

• 6D: Calabi-Yau manifold (CY?), dark matter ground state
• 18D: G? manifold, shen-spacetime
• 54D: Hyperkähler manifold, xu-spacetime
• 162D: Fractal/self-similar manifold, dao-spacetime

A.4 String Theory Interface

1. Vertex operators: STLT polarization maps to string vertex operators controlling matter ↔ dark energy transitions
2. T-duality: Corresponds to matter contraction ↔ dark energy expansion interchange
3. Conformal field theory: Polarization field Ω bridges worldsheet CFT

A.5 Topological Anomaly Compensation

Polarization processes as topological phase transitions:

$$S^{\text{bulk}}=S^{\text{CFT}}+{\int }^{\partial M}\Omega \wedge CS(A)$$

where $CS(A)$ is Chern-Simons form describing topological response during dark matter polarization.
