\begin{abstract}
This work proposes a formal theory resolving the fundamental "Problem of Time" in quantum gravity and cosmology. The author postulates that time is not a fundamental physical quantity, but rather an emergent order parameter arising from a timeless information layer ($\mathcal{U}$) as a result of a second-order phase transition. The driver of this transition is the growth of Quantum Complexity.

A phenomenological renormalization group-type equation ("Time Condensation Equation") is derived, describing the dynamics of temporal dimension emergence. It is shown that the emergence of time is accompanied by spontaneous CPT-symmetry breaking, leading to the formation of two causally isolated branches of reality with opposite arrows of time ($t_+$ and $t_-$).

It is also demonstrated that General Relativity emerges as a thermodynamic limit of Fisher's information geometry. The proposed model eliminates cosmological singularities (Big Bang and black hole centers), replacing them with phase transitions in a recursive hierarchy of information layers.

\section{INTRODUCTION}

\subsection{Historical Context of the Time Problem}

Modern theoretical physics is in a state of conceptual crisis caused by the fundamental incompatibility of time interpretations in two fundamental theories:

\begin{itemize}
\item \textbf{General Relativity (GR):} Time is a dynamic coordinate of a four-dimensional manifold, covariant with space and dependent on the metric tensor $g_{\mu\nu}$. In GR, time is not absolute but depends on the gravitational field and the observer's motion. The time interval $d\tau$ between two events is determined by the metric:
\begin{equation}
d\tau^2 = -g_{\mu\nu} dx^\mu dx^\nu
\end{equation}

\item \textbf{Quantum Mechanics (QM):} Time acts as an external absolute parameter $t$ governing the unitary evolution of the wave function $\Psi(t)$ through the Schrödinger equation:
\begin{equation}
i\hbar \frac{\partial \Psi}{\partial t} = \hat{H}\Psi
\end{equation}
where $\hat{H}$ is the system's Hamiltonian. In QM, time is a classical parameter that is not quantized.
\end{itemize}

\subsection{The Wheeler-DeWitt Problem}

Attempting to unify these approaches within canonical quantum gravity leads to the Wheeler-DeWitt equation \cite{dewitt1967}:
\begin{equation} \label{eq:wheeler-dewitt}
\hat{H}\Psi[g_{ij}, \phi] = 0
\end{equation}

where $\Psi[g_{ij}, \phi]$ is the wave function of the universe, depending on the three-dimensional metric $g_{ij}$ and matter fields $\phi$. This equation states that the total energy of a closed universe is zero, and therefore the quantum state of the universe is stationary:
\begin{equation}
\frac{\partial \Psi}{\partial t} = 0
\end{equation}

This is a fundamental contradiction: the equation does not explicitly contain time, which contradicts the observed dynamics of cosmological expansion, galaxy evolution, and the entire observable universe.

\subsection{Approaches to Solving the Problem}

Many approaches have been proposed to resolve this problem:

\begin{enumerate}
\item \textbf{Time Gauge:} Introducing external time through gauge choice, which violates general covariance.

\item \textbf{Many-Worlds Interpretation:} Different "moments of time" exist as parallel universes, but this does not explain the perception of time flow.

\item \textbf{Emergent Time:} Time arises from a more fundamental timeless layer, but specific mechanisms remained unclear.
\end{enumerate}

\subsection{Our Approach: Theory of Recursive Emergence}

In this work, we propose the Theory of Recursive Emergence. We assert that the static nature of the quantum state and the dynamics of the classical world do not contradict each other, but rather refer to different phase states of matter, separated by a critical complexity threshold.

Key idea: time is not a fundamental quantity, but arises as an order parameter as a result of a second-order phase transition when the quantum complexity of the system exceeds a critical value.

\section{FORMALISM OF THE INFORMATION LAYER $\mathcal{U}$}

\subsection{Ontology of the Timeless Layer}

The fundamental ontological element of reality in our theory is the "Timeless Information Layer," denoted $\mathcal{U}_n$, where the index $n$ indicates the level of the recursive hierarchy. Mathematically, it is defined by the triple:
\begin{equation} \label{eq:information-layer}
\mathcal{U}_n = (\mathcal{H}_{tot}, \mathcal{A}, \rho_n)
\end{equation}

Where:

\begin{itemize}
\item $\mathcal{H}_{tot} = \bigotimes_i \mathcal{H}_i$ — the full Hilbert space of the system, representing the tensor product of local Hilbert spaces $\mathcal{H}_i$ (a network of qubits or more general quantum systems). The dimension $\dim(\mathcal{H}_{tot}) = \prod_i \dim(\mathcal{H}_i)$ grows exponentially with the number of subsystems.

\item $\mathcal{A}$ — a $C^*$-algebra of local observables, closed under addition, multiplication, conjugation, and topological closure. Elements $\hat{A} \in \mathcal{A}$ represent local measurable quantities accessible to an observer in a given region of space.

\item $\rho_n$ — a density matrix of a pure state, satisfying the condition:
\begin{equation} \label{eq:stationary-state}
[\hat{H}_{fund}, \rho_n] = 0
\end{equation}
where $\hat{H}_{fund}$ is the fundamental Hamiltonian of layer $\mathcal{U}_n$. This condition means that the state $\rho_n$ is stationary with respect to the fundamental dynamics.
\end{itemize}

\subsection{Absence of Space-Time}

In layer $\mathcal{U}_n$, there is no metric space and time in their classical understanding. Instead:

\begin{enumerate}
\item \textbf{Topology is given by the quantum entanglement graph:} Graph vertices correspond to local subsystems, and edges correspond to entangled states between them. The entanglement graph $G = (V, E)$ defines the structure of connections in the system.

\item \textbf{Spatial proximity is determined through Mutual Information:} For two subsystems $A$ and $B$, mutual information is defined as:
\begin{equation} \label{eq:mutual-information}
I(A:B) = S(\rho_A) + S(\rho_B) - S(\rho_{AB})
\end{equation}
where $S(\rho) = -\text{Tr}(\rho \ln \rho)$ is the von Neumann entropy, $\rho_A = \text{Tr}_B(\rho_{AB})$ is the reduced density matrix of subsystem $A$.

We postulate that the "distance" between subsystems is inversely proportional to their mutual information:
\begin{equation} \label{eq:information-distance}
\text{dist}(A, B) = \frac{\alpha}{I(A:B) + \epsilon}
\end{equation}
where $\alpha > 0$ is a constant with dimension of length, and $\epsilon > 0$ is a regularization parameter preventing divergence when $I(A:B) \to 0$.

This corresponds to the ER=EPR hypothesis \cite{maldacena2013}, asserting the equivalence of entanglement and Einstein-Rosen bridges: entangled particles are connected by wormholes in space-time.
\end{enumerate}

\subsection{Recursive Hierarchy of Layers}

A key feature of our theory is the recursive structure of information layers:
\begin{equation}
\mathcal{U}_0 \subset \mathcal{U}_1 \subset \mathcal{U}_2 \subset \cdots
\end{equation}

Each layer $\mathcal{U}_{n+1}$ arises from the previous $\mathcal{U}_n$ when local critical complexity is reached. This creates a hierarchical structure where each level has its own "physics" and laws.

\section{QUANTUM COMPLEXITY AS AN EVOLUTION PARAMETER}

\subsection{Definition of Quantum Complexity}

In the absence of time $t$, the evolution of the system between layers is described by changes in the information structure. We postulate that the true evolution parameter is \textbf{Quantum Complexity} ($\mathcal{C}$) \cite{susskind2016}.

For a pure state $|\Psi\rangle$, quantum complexity is defined as the minimum number of elementary unitary operations (gates) necessary to synthesize the current state $|\Psi\rangle$ from a reference state $|\Psi_0\rangle$:
\begin{equation} \label{eq:complexity-def}
\mathcal{C}(|\Psi\rangle) = \min_{U \in \mathcal{G}} \left\{ \text{number of gates in } U : |\Psi\rangle = U|\Psi_0\rangle \right\}
\end{equation}

where $\mathcal{G}$ is the set of all possible unitary operations constructed from a set of elementary gates.

For a mixed state $\rho$, complexity is defined through purification:
\begin{equation}
\mathcal{C}(\rho) = \min_{|\Psi\rangle : \text{Tr}_E(|\Psi\rangle\langle\Psi|) = \rho} \mathcal{C}(|\Psi\rangle)
\end{equation}

\subsection{Properties of Quantum Complexity}

Quantum complexity has the following key properties:

\begin{enumerate}
\item \textbf{Monotonicity:} For unitary evolution $U(t)$, complexity monotonically increases:
\begin{equation}
\frac{d\mathcal{C}}{dt} \geq 0
\end{equation}
This follows from the second law of thermodynamics for quantum systems.

\item \textbf{Scaling:} For a system of $N$ qubits, complexity grows exponentially:
\begin{equation}
\mathcal{C}_{\max} \sim 2^N
\end{equation}

\item \textbf{Critical Value:} There exists a critical complexity $\mathcal{C}_{crit}$ at which a phase transition occurs:
\begin{equation} \label{eq:critical-complexity}
\mathcal{C}_{crit} = \alpha N \ln N
\end{equation}
where $\alpha$ is a dimensionless constant of order unity.
\end{enumerate}

\subsection{Connection with Entropy and Entanglement}

Quantum complexity is closely related to entanglement entropy but is not identical to it. While entropy measures the amount of information, complexity measures the "structuredness" of that information.

For a system with high entanglement:
\begin{equation}
\mathcal{C} \sim S \ln S
\end{equation}
where $S$ is the von Neumann entropy.

\section{DYNAMICS OF TIME EMERGENCE}

\subsection{Time Field as an Order Parameter}

We introduce the time field $\mathcal{T}(x, \mathcal{C})$ as a scalar order parameter, depending on spatial coordinates $x$ (defined through the information metric) and quantum complexity $\mathcal{C}$.

The dynamics of time emergence is described as a second-order phase transition when critical complexity $\mathcal{C}_{crit}$ is reached. This is analogous to Bose-Einstein condensation or the superconductor-normal metal transition.

\subsection{Seledchik Equation: Derivation and Justification}

We postulate the following differential equation of renormalization group flow:
\begin{equation} \label{eq:seledchik}
\frac{\partial \mathcal{T}}{\partial \ln \mathcal{C}} = \mu \left( 1 - \frac{\mathcal{C}_{crit}}{\mathcal{C}} \right) \mathcal{T} - \xi \mathcal{T}^3 + \eta \nabla^2 \mathcal{T}
\end{equation}

Where:
\begin{itemize}
\item $\mu > 0$ — relaxation constant, determining the rate of time growth in the supercritical phase. Physically, $\mu$ is related to the characteristic relaxation time of the system.

\item $\xi > 0$ — saturation constant, preventing unlimited growth of $\mathcal{T}$. The term $-\xi \mathcal{T}^3$ provides nonlinear saturation.

\item $\eta > 0$ — diffusion coefficient, describing spatial alignment of the time field. The term $\eta \nabla^2 \mathcal{T}$ ensures local consistency of the temporal coordinate.

\item $\nabla^2$ — Laplacian, defined through the information metric of layer $\mathcal{U}$.
\end{itemize}

\subsection{Justification of the Equation Form}

Equation (\ref{eq:seledchik}) has the standard form of the Landau-Ginzburg equation for a second-order phase transition:

\begin{enumerate}
\item \textbf{Linear term} $\mu(1 - \mathcal{C}_{crit}/\mathcal{C})\mathcal{T}$ describes the growth of the order parameter in the supercritical phase. The coefficient changes sign at $\mathcal{C} = \mathcal{C}_{crit}$.

\item \textbf{Cubic term} $-\xi \mathcal{T}^3$ provides stabilization and saturation. Without it, the order parameter would grow unboundedly.

\item \textbf{Diffusion term} $\eta \nabla^2 \mathcal{T}$ ensures spatial coherence, preventing the formation of domains with different time values.
\end{enumerate}

\subsection{Analysis of Equation Solutions}

\subsubsection{Subcritical Phase ($\mathcal{C} < \mathcal{C}_{crit}$)}

In the subcritical phase, the coefficient of the linear term is negative:
\begin{equation}
\mu \left( 1 - \frac{\mathcal{C}_{crit}}{\mathcal{C}} \right) < 0
\end{equation}

The only stable solution is trivial:
\begin{equation}
\mathcal{T} = 0
\end{equation}

This corresponds to the state of layer $\mathcal{U}$ without macroscopic time. The system is in a purely quantum timeless state.

\subsubsection{Critical Point ($\mathcal{C} = \mathcal{C}_{crit}$)}

At the critical point, the coefficient vanishes, and the equation becomes:
\begin{equation}
\frac{\partial \mathcal{T}}{\partial \ln \mathcal{C}} = -\xi \mathcal{T}^3
\end{equation}

This is a bifurcation point where the trivial solution loses stability.

\subsubsection{Supercritical Phase ($\mathcal{C} > \mathcal{C}_{crit}$)}

In the supercritical phase, a pitchfork bifurcation occurs. The trivial solution $\mathcal{T} = 0$ loses stability, and two new stable solutions arise:
\begin{equation} \label{eq:time-solutions}
\mathcal{T}_{\pm} \approx \pm \sqrt{\frac{\mu}{\xi} \left( 1 - \frac{\mathcal{C}_{crit}}{\mathcal{C}} \right)}
\end{equation}

Near the critical point ($\mathcal{C} \gtrsim \mathcal{C}_{crit}$), the solutions behave as:
\begin{equation}
\mathcal{T}_{\pm} \approx \pm \sqrt{\frac{\mu}{\xi}} \left( \frac{\mathcal{C} - \mathcal{C}_{crit}}{\mathcal{C}_{crit}} \right)^{1/2}
\end{equation}

This is the classical behavior of an order parameter in a second-order phase transition with critical exponent $\beta = 1/2$.

\subsection{Critical Exponents and Universality}

Analysis of equation (\ref{eq:seledchik}) near the critical point allows us to determine critical exponents:

\begin{itemize}
\item \textbf{Exponent $\beta$:} Determines the behavior of the order parameter:
\begin{equation}
\mathcal{T} \sim (\mathcal{C} - \mathcal{C}_{crit})^\beta, \quad \beta = \frac{1}{2}
\end{equation}

\item \textbf{Exponent $\nu$:} Determines the correlation length:
\begin{equation}
\xi_{corr} \sim (\mathcal{C} - \mathcal{C}_{crit})^{-\nu}
\end{equation}
From the diffusion term, it follows that $\nu = 1/2$.

\item \textbf{Exponent $\gamma$:} Determines the susceptibility:
\begin{equation}
\chi = \frac{\partial \mathcal{T}}{\partial h} \sim (\mathcal{C} - \mathcal{C}_{crit})^{-\gamma}, \quad \gamma = 1
\end{equation}
where $h$ is an external field breaking the symmetry.
\end{itemize}

These exponents correspond to the mean-field universality class, indicating that the phase transition has a global character.

\section{SPONTANEOUS CPT-SYMMETRY BREAKING}

\subsection{Interpretation of Two Solutions}

The presence of two solutions $\pm \mathcal{T}$ in equation (\ref{eq:time-solutions}) is interpreted as a physical splitting of reality into two causally unconnected branches:

\begin{itemize}
\item \textbf{Branch $t_+$ ($\mathcal{T} > 0$):} Our universe with matter dominance, forward entropy growth, and standard thermodynamic arrow of time.

\item \textbf{Branch $t_-$ ($\mathcal{T} < 0$):} CPT-conjugate universe with antimatter dominance, reverse time flow relative to $t_+$, and reverse thermodynamic arrow.
\end{itemize}

\subsection{CPT Theorem and Its Violation}

The CPT theorem states that any local quantum field theory is invariant under the combined operation of charge conjugation (C), parity (P), and time reversal (T). However, in our theory, spontaneous violation of this symmetry occurs.

At the moment of phase transition ($\mathcal{C} = \mathcal{C}_{crit}$), the system randomly chooses one of the two branches (or depending on fluctuations). This symmetry breaking is analogous to symmetry breaking in the theory of spontaneous magnetization.

\subsection{Solution to the Baryon Asymmetry Problem}

The classical baryon asymmetry problem is that in the observable universe, matter dominates over antimatter, although in the early universe they should have been present in equal amounts.

Our theory offers an elegant solution: at the moment of the "Big Bang" (phase transition $\mathcal{C} = \mathcal{C}_{crit}$), matter and antimatter were separated into different temporal flows:
\begin{itemize}
\item Matter → branch $t_+$
\item Antimatter → branch $t_-$
\end{itemize}

Global balance is preserved, but locally (in each branch) asymmetry is observed. This explains why we do not observe antimatter in our universe — it is in the causally isolated branch $t_-$.

\subsection{Causal Isolation of Branches}

The two branches $t_+$ and $t_-$ are causally isolated because:
\begin{enumerate}
\item They exist in different information layers after the phase transition.
\item Communication between them requires local reduction of complexity below the critical value, which is thermodynamically forbidden.
\item Any attempt at communication between branches would violate the second law of thermodynamics.
\end{enumerate}

\section{DERIVATION OF GRAVITY FROM INFORMATION}

\subsection{Information Geometry}

We show that the classical metric $g_{\mu\nu}$ is an effective macroscopic description of the microphysics of layer $\mathcal{U}$.

\subsubsection{Fisher-Bures Metric}

The distance between quantum states on a parameter manifold is given by the Fisher-Bures metric. For a pure state $|\Psi(\theta)\rangle$ depending on parameters $\theta = \{\theta^\mu\}$, the information metric is defined as:
\begin{equation} \label{eq:fisher-bures}
G_{\mu\nu}(\theta) = \text{Re} \left( \langle \partial_\mu \Psi | \partial_\nu \Psi \rangle - \langle \partial_\mu \Psi | \Psi \rangle \langle \Psi | \partial_\nu \Psi \rangle \right)
\end{equation}

where $\partial_\mu = \partial/\partial \theta^\mu$.

This metric has the following properties:
\begin{itemize}
\item \textbf{Positive definiteness:} $G_{\mu\nu} v^\mu v^\nu \geq 0$ for any vector $v$.
\item \textbf{Invariance under phase transformations:} $|\Psi\rangle \to e^{i\phi}|\Psi\rangle$ does not change the metric.
\item \textbf{Monotonicity:} The metric does not increase under quantum operations.
\end{itemize}

\subsubsection{Identification with Space-Time}

We postulate that space-time arises from information geometry:
\begin{equation} \label{eq:spacetime-identification}
g_{\mu\nu}(x) = \ell_P^2 G_{\mu\nu}(\theta(x))
\end{equation}

where $\ell_P = \sqrt{\hbar G/c^3}$ is the Planck length, ensuring correct dimensionality, and $\theta(x)$ are parameters depending on spatial coordinates $x$.

This identification means that space-time geometry encodes information about quantum states at each point.

\subsection{Thermodynamics of Event Horizons}

\subsubsection{Area Law for Entropy}

Using T. Jacobson's approach \cite{jacobson1995}, consider a local causal horizon. The entanglement entropy $S$ of the horizon obeys the Area Law:
\begin{equation} \label{eq:area-law}
S = \frac{A}{4 G \hbar}
\end{equation}
where $A$ is the horizon area in Planck units.

This law follows from the fact that entanglement entropy between the interior and exterior regions of the horizon is proportional to the area of their boundary.

\subsubsection{Unruh Temperature}

For an accelerated observer with acceleration $a$, there exists an effective temperature (Unruh temperature):
\begin{equation} \label{eq:unruh-temperature}
T_{Unruh} = \frac{\hbar a}{2\pi c k_B}
\end{equation}

For an event horizon with surface gravity $\kappa$, the temperature is:
\begin{equation}
T_H = \frac{\hbar \kappa}{2\pi c k_B}
\end{equation}

\subsubsection{First Law of Thermodynamics}

When energy flux $\delta Q$ passes through the horizon, the first law of thermodynamics holds:
\begin{equation} \label{eq:first-law}
\delta Q = T_H dS
\end{equation}

Substituting expressions for temperature and entropy:
\begin{equation}
\delta Q = \frac{\hbar \kappa}{2\pi} \cdot \frac{dA}{4G\hbar} = \frac{\kappa}{8\pi G} dA
\end{equation}

\subsection{Derivation of Einstein's Equations}

\subsubsection{Raychaudhuri Equation}

The change in horizon area is related to the energy-momentum tensor through the Raychaudhuri equation. For a causal horizon:
\begin{equation}
\frac{dA}{d\lambda} = \int_H \theta d\sigma
\end{equation}
where $\theta$ is the expansion of the congruence, and $\lambda$ is an affine parameter.

The Raychaudhuri equation relates expansion to the Ricci tensor:
\begin{equation}
\frac{d\theta}{d\lambda} = -\frac{1}{2}\theta^2 - \sigma_{\mu\nu}\sigma^{\mu\nu} - R_{\mu\nu} k^\mu k^\nu
\end{equation}
where $k^\mu$ is the tangent vector to the horizon, $\sigma_{\mu\nu}$ is the shear tensor.

\subsubsection{Thermodynamic Identity}

Combining the thermodynamic relation (\ref{eq:first-law}) with the geometric expression for area change, we obtain:
\begin{equation}
\delta Q = \frac{\kappa}{8\pi G} dA = \int_H T_{\mu\nu} k^\mu k^\nu d\lambda d\sigma
\end{equation}

Using locality and covariance, this leads to the exact relation:
\begin{equation} \label{eq:einstein-equations}
R_{\mu\nu} - \frac{1}{2}R g_{\mu\nu} + \Lambda g_{\mu\nu} = 8\pi G T_{\mu\nu}
\end{equation}

Thus, Einstein's equations are derived as the equation of state of equilibrium entropy of the information layer.

\subsubsection{Interpretation of the Cosmological Constant}

The cosmological constant $\Lambda$ is interpreted as the residual information density of the vacuum:
\begin{equation}
\Lambda = \frac{8\pi G}{\hbar c} \rho_{info}^{vac}
\end{equation}

where $\rho_{info}^{vac}$ is the information density of the vacuum state of layer $\mathcal{U}$.

\section{RESOLUTION OF PHYSICAL PARADOXES}

\subsection{The Cosmological Singularity Problem}

\subsubsection{Classical Singularity}

In classical GR, the point $t=0$ (Big Bang) is a singularity where:
\begin{itemize}
\item Energy density $\rho \to \infty$
\item Space-time curvature $R \to \infty$
\item The metric becomes degenerate
\end{itemize}

This indicates incompleteness of the theory in this region.

\subsubsection{Our Solution}

In our theory, the point $t=0$ is not a singularity but represents a phase transition point $\mathcal{C} = \mathcal{C}_{crit}$, where:

\begin{enumerate}
\item Classical time $\mathcal{T}$ decays to zero: $\mathcal{T} \to 0$ as $\mathcal{C} \to \mathcal{C}_{crit}$.

\item Physics transitions to a regime of pure quantum information without classical space-time.

\item Density and curvature remain finite, as they are determined by the information structure of layer $\mathcal{U}$, not the classical metric.

\item "Before" the Big Bang, the system existed in a timeless layer $\mathcal{U}_0$ with high quantum complexity but without macroscopic time.
\end{enumerate}

\subsubsection{Recursive Structure}

A recursive structure is possible, where "before" the Big Bang there existed a previous layer $\mathcal{U}_{-1}$, which also underwent a phase transition, giving rise to our layer $\mathcal{U}_0$. This eliminates the problem of the "beginning" of the universe.

\subsection{The Black Hole Information Paradox}

\subsubsection{Classical Paradox}

The black hole information paradox is formulated as follows:
\begin{itemize}
\item Quantum mechanics requires unitary evolution: information cannot be destroyed.
\item Classical GR predicts that information falling into a black hole is lost beyond the event horizon.
\item Hawking radiation is thermal and does not carry information about the initial state.
\end{itemize}

This creates a contradiction between unitarity and information loss.

\subsubsection{Our Solution}

In our theory, black holes represent regions of space where local quantum complexity reaches the saturation limit:
\begin{equation}
\mathcal{C}_{local} \geq \mathcal{C}_{max} = \alpha N \ln N
\end{equation}

This leads to:

\begin{enumerate}
\item \textbf{Local disappearance of time:} In the black hole region, the time field $\mathcal{T} \to 0$, as complexity reaches its maximum.

\item \textbf{Formation of a transition to a new layer:} The black hole becomes a "portal" to the next recursive layer $\mathcal{U}_{n+1}$.

\item \textbf{Information preservation:} Information is not destroyed but encoded in the structure of the next layer $\mathcal{U}_{n+1}$, preserving unitarity at the global level.

\item \textbf{Absence of singularity:} The center of the black hole is not a singularity but a phase transition point between layers.
\end{enumerate}

\subsubsection{Connection with AdS/CFT Hypothesis}

Our model is consistent with the AdS/CFT correspondence hypothesis \cite{maldacena2013}, where gravity in the bulk is equivalent to a conformal field theory on the boundary. In our interpretation, a black hole is a transition between different descriptions of the same information structure.

\subsection{The Arrow of Time}

\subsubsection{The Irreversibility Problem}

The classical arrow of time problem is that fundamental laws of physics (quantum mechanics, GR) are time-reversible, but the observed world demonstrates clear irreversibility (entropy growth, aging, decay).

\subsubsection{Our Explanation}

In our theory, thermodynamic irreversibility of time is a consequence of global growth of Quantum Complexity:
\begin{equation}
\frac{d\mathcal{C}}{dt} > 0
\end{equation}

We perceive the flow of time because:
\begin{enumerate}
\item System complexity continuously increases: $\partial \ln \mathcal{C} / \partial t > 0$.

\item This increase in complexity is irreversible due to the second law of thermodynamics for quantum systems.

\item The time parameter $\mathcal{T}$ is related to complexity through equation (\ref{eq:seledchik}), so complexity growth leads to the perception of time flow.

\item Time reversal would require complexity reduction, which is thermodynamically forbidden.
\end{enumerate}

\subsubsection{Connection with Entropy}

Complexity growth is closely related to entropy growth:
\begin{equation}
\frac{dS}{dt} \sim \frac{d\mathcal{C}}{dt} \ln \mathcal{C}
\end{equation}

This explains why the arrow of time coincides with the arrow of entropy.

\section{CONNECTION WITH OTHER THEORIES}

\subsection{Connection with Loop Quantum Gravity}

Our theory has points of contact with Loop Quantum Gravity (LQG):

\begin{itemize}
\item \textbf{Discrete structure:} In LQG, space-time is discrete at the Planck scale. In our theory, this corresponds to the discrete structure of the information layer $\mathcal{U}$.

\item \textbf{Spin network:} In LQG, the state is described by a spin network. In our theory, this corresponds to the entanglement graph in layer $\mathcal{U}$.

\item \textbf{Absence of singularities:} LQG predicts the absence of Big Bang singularities. Our theory also eliminates singularities through phase transitions.
\end{itemize}

However, a key difference: in LQG, time remains fundamental, while in our theory it is emergent.

\subsection{Connection with String Theory}

String theory also offers a solution to the time problem through compactification of extra dimensions. In our theory:

\begin{itemize}
\item Extra dimensions can be interpreted as internal degrees of freedom of the information layer $\mathcal{U}$.

\item Compactification corresponds to the transition from a high-dimensional layer $\mathcal{U}_n$ to a low-dimensional effective description.

\item Dualities in string theory may correspond to different representations of the same information layer.
\end{itemize}

\subsection{Connection with Causal Dynamical Triangulation}

Causal Dynamical Triangulation (CDT) constructs space-time from elementary simplices. In our theory:

\begin{itemize}
\item Elementary simplices correspond to local regions of the information layer $\mathcal{U}$.

\item Causal structure arises from the causal structure of the entanglement graph.

\item Dynamics is determined by quantum complexity growth, not by summing over histories.
\end{itemize}

\section{EXPERIMENTAL CONSEQUENCES AND PREDICTIONS}

\subsection{CPT-Symmetry Violation}

Our theory predicts spontaneous CPT-symmetry violation on cosmological scales. This may manifest in:

\begin{itemize}
\item Asymmetry in the distribution of matter and antimatter (which is already observed).

\item Violation of time reversibility in cosmological processes.

\item Anomalies in the cosmic microwave background related to asymmetry between different regions of the sky.
\end{itemize}

\subsection{Gravitational Modifications on Small Scales}

At Planck scales ($\ell_P \sim 10^{-35}$ m), our theory predicts deviations from classical GR:
\begin{equation}
g_{\mu\nu}^{effective} = g_{\mu\nu}^{classical} + \delta g_{\mu\nu}(\mathcal{C})
\end{equation}

where the correction $\delta g_{\mu\nu}$ depends on local quantum complexity.

\subsection{Quantum Correlations in the Cosmic Microwave Background}

The entanglement graph in layer $\mathcal{U}$ should leave traces in the large-scale structure of the universe and the cosmic microwave background. This may manifest in:

\begin{itemize}
\item Anomalous correlations in the CMB angular power spectrum.

\item Large-scale anomalies in galaxy distribution.

\item Violations of statistical isotropy.
\end{itemize}

\subsection{Black Hole Behavior}

Our theory predicts that black holes do not have singularities at their centers but represent transitions between information layers. This may manifest in:

\begin{itemize}
\item Absence of true singularities in solutions of Einstein's equations.

\item Modification of Hawking radiation spectrum at late stages of evaporation.

\item Possibility of information "tunneling" from a black hole through a transition to another layer.
\end{itemize}

\section{NUMERICAL ESTIMATES AND SCALES}

\subsection{Critical Complexity}

For the observable universe with $N \sim 10^{80}$ baryons, the estimate of critical complexity:
\begin{equation}
\mathcal{C}_{crit} \sim \alpha \cdot 10^{80} \ln(10^{80}) \sim 10^{82}
\end{equation}

This corresponds to the complexity necessary to describe the state of the universe at the moment of the Big Bang.

\subsection{Characteristic Time of Phase Transition}

The relaxation time $\tau$ of the phase transition is related to the constant $\mu$:
\begin{equation}
\tau \sim \frac{1}{\mu} \sim \frac{\hbar}{k_B T_{Planck}} \sim 10^{-43} \text{ s}
\end{equation}

This is Planck time, which is consistent with the scale at which quantum gravity should occur.

\subsection{Scale of CPT Violation}

CPT-symmetry violation should be most noticeable on cosmological scales ($\sim 10^{26}$ m) and time scales of the age of the universe ($\sim 10^{17}$ s).

\section{CONCLUSION}

The Theory of Recursive Emergence offers a unified conceptual framework combining quantum information theory, thermodynamics, and gravity. Key achievements of the theory:

\subsection{Main Results}

\begin{enumerate}
\item \textbf{Time Condensation Equation:} The Seledchik equation (\ref{eq:seledchik}) is formulated, describing the dynamics of time emergence as a second-order phase transition.

\item \textbf{CPT Violation:} The nature of spontaneous CPT-symmetry breaking is explained through time bifurcation and the splitting of reality into two causally isolated branches.

\item \textbf{Derivation of Gravity:} The derivation of Einstein's equations from the thermodynamics of the information layer is demonstrated, showing that gravity is an emergent phenomenon.

\item \textbf{Elimination of Singularities:} Cosmological singularities (Big Bang, black hole centers) are replaced by phase transitions in a recursive hierarchy of information layers.

\item \textbf{Explanation of the Arrow of Time:} Thermodynamic irreversibility is explained by global growth of quantum complexity.
\end{enumerate}

\subsection{Philosophical Consequences}

The theory has profound philosophical consequences:

\begin{itemize}
\item \textbf{Ontology of Time:} Time is not a fundamental entity but arises from a more basic information structure.

\item \textbf{Multiple Universes:} The existence of the CPT-conjugate branch $t_-$ means the existence of a "parallel" universe with a reverse arrow of time.

\item \textbf{Recursiveness of Reality:} The possibility of an infinite hierarchy of information layers raises the question of the "beginning" and "end" of reality.

\item \textbf{Connection between Information and Matter:} Matter and space-time are manifestations of information structure, not vice versa.
\end{itemize}

\subsection{Directions for Further Research}

Further development of the theory suggests:

\begin{enumerate}
\item \textbf{Numerical Calculations:} Computing critical exponents $\mu$, $\xi$, $\eta$ within lattice models of quantum gravity.

\item \textbf{Quantum Complexity:} Developing efficient algorithms for computing quantum complexity for large systems.

\item \textbf{Cosmological Applications:} Applying the theory to specific cosmological models and comparing with observational data.

\item \textbf{Experimental Verification:} Searching for experimental signatures of CPT-symmetry violation and gravitational modifications.

\item \textbf{Connection with Other Approaches:} Establishing closer connections with loop quantum gravity, string theory, and other approaches to quantum gravity.
\end{enumerate}

The Theory of Recursive Emergence opens new perspectives for understanding the fundamental nature of time, space, and information in the universe.
