Abstract

Standard Friedmann–Lemaître–Robertson–Walker (FLRW) cosmology fixes the temporal metric component to unity: $g_{00} \equiv -1$. This condition asserts that the proper time of co-moving observers matches universal coordinate time ($d\tau = dt$) identically across all epochs, regardless of cosmic mass-energy density. This paper proves that this postulate introduces an internal physical and mathematical contradiction into General Relativity.

The justification for $g_{00} = -1$ rests on a category error regarding Newton’s Shell Theorem: while spatial homogeneity causes gravitational vector forces to cancel identically ($\nabla \Phi = \mathbf{0}$), scalar gravitational potentials do not cancel; they accumulate. Because an expanding distribution of matter is defined by increasing separation between mass elements ($\dot{R}_{ij} > 0$), the cumulative scalar potential well ($\Phi_{\text{total}} = -\sum G M_i / R_i$) is monotonically shallowing ($\frac{d}{dt}|\Phi_{\text{total}}| < 0$). In standard General Relativity, the rate of proper time is governed by the scalar potential depth, not its spatial gradient. Consequently, in any expanding mass distribution, the rate of physical time must accelerate ($\frac{d}{dt}(d\tau/dt) > 0$). Holding $g_{00} = -1$ while allowing spatial expansion constitutes an unphysical decoupling of the metric’s temporal component from the gravitational consequence of its spatial evolution.

This critique is strictly internal to General Relativity: the metric coupling $g_{00}(\Phi)$ employs standard relativistic potential-time dilation in the weak-field limit and standard relativistic compaction thresholds (the Buchdahl limit) in the strong-field limit. The error lies not in General Relativity, but in FLRW’s specific coordinate ansatz.

We prove the Local Invariance Theorem: local observers cannot detect this temporal acceleration using co-local apparatuses, because the metric lapse cancels identically out of every internal measurement ratio. We identify spectral redshift as the direct ratio of clock tick rates between epochs in a shallowing well ($1+z = \sqrt{-g_{00}(t_{\text{now}})}/\sqrt{-g_{00}(t_{\text{emit}})}$).

Finally, we establish the general open boundary problem of this framework: because the audit rejects the FLRW metric ansatz, it cannot borrow Friedmann dynamics to evaluate quantitative claims. The exact functional form of matter dispersal $\rho(t)$, the metric lapse $g_{00}(t)$, the convergence or divergence of the past dynamical action integral ($N_{\text{dyn}}$), and the luminosity distance relation $d_L(z)$ cannot be determined by kinematics alone. We formally define the coupled self-consistent field equations required to solve these quantities from first principles within General Relativity, establishing that the empirical resolutions of Dark Energy, the JWST early-galaxy paradox, and the Horizon Problem are quantitative predictions that hang strictly on the solution to this open dynamical problem.

1. The FLRW Metric Postulate

In modern cosmology, the large-scale geometry of the universe is represented by the FLRW metric: $$ds^2 = -c^2 dt^2 + a(t)^2 \left( \frac{dr^2}{1 - kr^2} + r^2 d\Omega^2 \right)$$

This metric separates spacetime into a dynamic 3-dimensional spatial slice scaled by $a(t)$ and a 1-dimensional temporal axis parameterized by coordinate time $t$. The metric components are: $$g_{ij} = a(t)^2 \gamma_{ij}, \quad g_{00} \equiv -1$$

The condition $g_{00} \equiv -1$ dictates that for any co-moving observer ($dx^i = 0$): $$d\tau = \sqrt{-g_{00}} \, dt = dt$$

This assumes that an atomic clock operating in the hyper-dense plasma of the early universe ticks at the exact same rate per unit coordinate time $t$ as an identical atomic clock operating in a diluted, low-density modern epoch.

The standard justification for this assumption relies on the Cosmological Principle: because matter is distributed homogeneously and isotropically on large scales, there are no net gravitational force vectors acting on co-moving observers. From this vanishing gradient, standard cosmology asserts the absence of gravitational time dilation, setting $g_{00} = -1$.

---

2. The Category Error: Vectors Cancel, Scalars Add

The deduction that a homogeneous universe lacks gravitational time dilation is based on a failure to distinguish between vector fields and scalar fields in potential theory.

2.1. Newton’s Shell Theorem

Consider a static, spherically symmetric shell of mass $M$ and radius $R$. By Gauss’s Law for gravitation, the gravitational field vector $\vec{g}$ at any point inside the shell ($r < R$) vanishes: $$\vec{g}(r) = -\nabla \Phi = \mathbf{0} \quad (\forall \, r < R)$$

The vector sum of forces from diametrically opposed surface elements cancels identically due to the inverse-square law and geometric solid-angle projection.

However, the gravitational potential $\Phi$ within the shell does not vanish. Because potential is a scalar, it possesses no spatial direction. Evaluating the line integral from infinity to an interior point $r < R$: $$\Phi(r) = -\int_\infty^R \frac{GM}{r'^2} \, dr' - \int_R^r \mathbf{0} \cdot d\vec{r}' = -\frac{GM}{R} \quad (\forall \, r < R)$$

The interior of the shell is equipotential, but that potential is strictly negative and non-zero.

In General Relativity, the temporal metric component $g_{00}$ for a clock at rest in a static gravitational field is determined by the scalar potential: $$g_{00} = -\left(1 + \frac{2\Phi}{c^2}\right) = -\left(1 - \frac{2GM}{Rc^2}\right) \neq -1$$

An observer inside the shell experiences zero proper acceleration ($\vec{g} = \mathbf{0}$) and measures zero net mechanical force. Yet, an atomic clock inside this shell ticks slower than an identical clock located at infinity ($R \to \infty$). Gravitational time dilation is governed by the scalar potential depth, not by the vector force gradient.

2.2. The Cosmological Sum

Now consider an observer situated within a continuous, isotropic, homogeneous mass distribution. By spherical symmetry around any arbitrary origin, the mass distribution can be foliated into concentric, continuous spherical shells of radius $r$ and thickness $dr$:

$$\vec{g}_{\text{total}} = \int_{\text{cosmos}} d\vec{g} = \mathbf{0}$$

As expected, the vector forces cancel to zero. However, the scalar potential is the cumulative sum of all enclosing shells: $$\Phi_{\text{total}} = \int_{\text{cosmos}} d\Phi = -4\pi G \int_0^{R_{\text{boundary}}} \rho(r) \, r \, dr \neq 0$$

Every shell of matter contributes an additional negative scalar value to the potential at the center.

The Category Error: Standard cosmology observes that $\vec{g}_{\text{total}} = -\nabla \Phi_{\text{total}} = \mathbf{0}$, conflates a zero gradient with a zero potential, and sets $g_{00} = -1$.

Vectors cancel because they have direction. Scalars add because they have magnitude. An observer in a homogeneous universe floats weightlessly because the vectors cancel, but their temporal metric is embedded in the scalar sum of every mass shell in the cosmos.

3. The Deductive Theorem: Expansion Implies Potential Shallowing

Once it is established that $\Phi_{\text{total}} \neq 0$, its behavior under cosmic expansion is mathematically determined.

Let a distribution of matter have total mass $M_{\text{total}}$ within a bounded or causally connected region of characteristic radius $R(t)$.

1. Definition of Expansion:
   A distribution of mass is expanding if and only if the physical distance $R_{ij}$ between arbitrary, non-bound mass elements increases over time: $$\frac{d}{dt} R_{ij}(t) > 0 \quad (\forall \, i \neq j)$$

2. The Scalar Potential Form:
   The cumulative scalar gravitational potential at any point within the distribution is: $$\Phi_{\text{total}}(t) = -G \sum_i \frac{M_i}{R_i(t)}$$

3. Deductive Step:
   Assuming mass conservation ($\dot{M}_i = 0$), we take the time derivative of the absolute potential depth: $$\frac{d}{dt} |\Phi_{\text{total}}(t)| = \frac{d}{dt} \left( G \sum_i \frac{M_i}{R_i(t)} \right) = -G \sum_i \frac{M_i}{R_i(t)^2} \frac{d R_i}{dt}$$

Since $M_i > 0$, $R_i > 0$, and $\frac{d R_i}{dt} > 0$: $$\frac{d}{dt} |\Phi_{\text{total}}(t)| < 0$$

Theorem 1: In any expanding distribution of mass, the absolute depth of the cumulative scalar gravitational potential well decreases monotonically over time. The potential well is, by definition, shallowing.

---

4. The Metric Consequence: Accelerating Proper Time

In General Relativity, the invariant spacetime interval along a worldline is: $$d\tau^2 = -g_{00}(t) \, dt^2$$

Where $g_{00}$ is coupled to the scalar potential of the mass-energy distribution. In the weak-to-intermediate field regime of standard General Relativity: $$-g_{00}(t) = 1 - \frac{2|\Phi_{\text{total}}(t)|}{c^2}$$

Differentiating with respect to the coordinate time $t$: $$\frac{d}{dt} (-g_{00}(t)) = -\frac{2}{c^2} \frac{d}{dt} |\Phi_{\text{total}}(t)|$$

From Theorem 1, $\frac{d}{dt} |\Phi_{\text{total}}(t)| < 0$. Therefore: $$\frac{d}{dt} (-g_{00}(t)) > 0$$

Taking the proper time rate: $$\frac{d\tau}{dt} = \sqrt{-g_{00}(t)}$$ $$\frac{d}{dt} \left( \frac{d\tau}{dt} \right) = \frac{1}{2\sqrt{-g_{00}(t)}} \frac{d}{dt} (-g_{00}(t)) > 0$$

Theorem 2: In any expanding mass distribution, the rate of proper time for all co-moving observers is strictly accelerating with respect to coordinate time.

The Inherent Contradiction of FLRW

The standard FLRW metric: $$ds^2 = -c^2 dt^2 + a(t)^2 d\Sigma^2$$ asserts simultaneously: 1. $\dot{a}(t) > 0$ (The mass distribution is expanding). 2. $g_{00}(t) \equiv -1 \implies \frac{d}{dt}(-g_{00}) = 0$ (The rate of time is constant).

Condition 1 mathematically demands $\frac{d}{dt}|\Phi_{\text{total}}| < 0$, which by standard General Relativity forces $\frac{d}{dt}(-g_{00}) > 0$. Condition 2 forbids this response. The FLRW metric allows mass elements to separate spatially while exempting the temporal metric from the gravitational consequence of that separation. It is an internally inconsistent equation.

---

5. The Local Invariance Theorem

Why has this cosmic temporal acceleration not been measured in terrestrial laboratories? We prove that it is locally undetectable.

Let a local laboratory contain two physical clocks based on distinct physical mechanisms: Clock $A$ (transition frequency $\omega_A$) and Clock $B$ (transition frequency $\omega_B$).

In a metric with temporal component $g_{00}(t)$, the physical Hamiltonian $\hat{H}$ governing any local quantum or mechanical state scales with the local lapse function $N(t) \equiv \sqrt{-g_{00}(t)}$: $$i\hbar \frac{d}{dt} |\psi\rangle = \hat{H}(t) |\psi\rangle = \sqrt{-g_{00}(t)} \, \hat{H}_0 |\psi\rangle$$

The coordinate frequency of both processes is shifted identically by the local background metric: $$\omega_A(t) = \omega_{0, A} \sqrt{-g_{00}(t)}, \quad \omega_B(t) = \omega_{0, B} \sqrt{-g_{00}(t)}$$

An observer measuring Clock $A$ against Clock $B$ measures the dimensionless ratio of cycles over an arbitrary coordinate interval $\Delta t$: $$\mathcal{R} \equiv \frac{\int_{\Delta t} \omega_A(t) \, dt}{\int_{\Delta t} \omega_B(t) \, dt} = \frac{\omega_{0, A} \int_{\Delta t} \sqrt{-g_{00}(t)} \, dt}{\omega_{0, B} \int_{\Delta t} \sqrt{-g_{00}(t)} \, dt} = \frac{\omega_{0, A}}{\omega_{0, B}}$$

Differentiating with respect to the temporal metric component: $$\frac{\partial \mathcal{R}}{\partial g_{00}} \equiv 0$$

Theorem 3 (Local Invariance):
No co-local apparatus can detect a monotonic change in the background metric component $g_{00}(t)$. The measured rate of proper time per unit proper time is an invariant identity: $$\frac{d\tau}{d\tau} \equiv 1$$

Local operational experiments are blind to the global shallowing of the potential. The acceleration of time can only be observed by comparing signals across cosmic epochs where the emitter and the receiver occupied different potential depths.

6. The Past Dynamical Action Integral as a Conditional Boundary

Standard cosmology integrates backward to a finite temporal boundary ($t_{\text{age}} \approx 13.8\text{ Gyr}$). This finite result depends on the axiom $g_{00} \equiv -1$. When the temporal metric is coupled to the scalar potential, the duration of past physical history must be evaluated by the number of dynamical cycles that could physically occur within the dispersing fluid.

6.1. The Dynamical Cycle Integral

In any self-gravitating fluid of density $\rho$, the characteristic timescale governing gravitational collapse, orbital periods, and structural relaxation is the free-fall time: $$t_{\text{dyn}}(\rho) = \frac{1}{\sqrt{G \rho}}$$

The total number of dynamical cycles $N_{\text{dyn}}$ that elapse between an early boundary ($t = 0$) and a subsequent epoch ($t_1$) is: $$N_{\text{dyn}} = \int_0^{t_1} \frac{dt}{t_{\text{dyn}}(t)} = \sqrt{G} \int_0^{t_1} \sqrt{\rho(t)} \, dt$$

6.2. The Dynamical Dependency on $\rho(t)$

In standard FLRW cosmology, density scales near the origin as $\rho(t) \propto t^{-2}$ (from the Friedmann equation $H^2 \propto \rho$). If one assumes this scaling: $$N_{\text{dyn}} \propto \int_0^{t_1} \frac{dt}{t} = \left[ \ln t \right]_0^{t_1} \longrightarrow \mathbf{\infty}$$

Under this specific power law, $N_{\text{dyn}}$ diverges logarithmically, providing an infinite sequence of physical dynamical cycles prior to any finite coordinate time $t_1$.

The Epistemic Boundary:
However, because this framework rejects the FLRW metric ansatz, it cannot borrow the Friedmann scaling $\rho(t) \propto t^{-2}$ without committing a circular derivation.

The true behavior of $N_{\text{dyn}}$ depends entirely on the self-consistent equation of motion for matter dispersing under a dynamic temporal metric $g_{00}(\Phi)$: * If the self-consistent dynamics produce $\rho(t) \propto t^{-n}$ with $n \ge 2$, then $N_{\text{dyn}} \to \infty$. In this regime, past dynamical time is infinite: the JWST high-$z$ galaxy maturity puzzle is resolved (galaxies had infinite dynamical cycles to mature), and the Horizon Problem is eliminated (causal contact was asymptotically complete without Cosmic Inflation). * If the self-consistent dynamics produce $n < 2$ (for example, linear expansion in an uncurved void where $\rho(t) \propto t^{-1}$), then: $$N_{\text{dyn}} \propto \int_0^{t_1} t^{-1/2} \, dt = 2\sqrt{t_1} < \mathbf{\infty}$$ In this regime, the dynamical cycle integral converges, and the framework cannot resolve the JWST or Horizon puzzles without auxiliary mechanisms.

Therefore, the claim that past dynamical time diverges is not a closed deduction of kinematics alone. It is a testable, conditional prediction that depends strictly on the solution to the general dynamical problem formulated in Section 8.

7. Cosmological Redshift as a Metric Clock Ratio

Spectral redshift is traditionally modeled as the stretching of photon wavelengths across expanding space: $$1 + z = \frac{a(t_{\text{now}})}{a(t_{\text{then}})}$$

Under Theorem 2, redshift is deduced as the relative frequency ratio of two clocks situated at different depths in the cosmic potential well.

Let an atom emit a photon via a quantum transition with proper rest frequency $\omega_0$ at epoch $t_{\text{emit}}$. At the moment of emission, the cosmic potential was deeper ($|\Phi(t_{\text{emit}})| > |\Phi(t_{\text{now}})|$). The coordinate frequency of the emitted photon is: $$\omega_{\text{emit}} = \omega_0 \sqrt{-g_{00}(t_{\text{emit}})}$$

The photon propagates through the 3D void. At the moment of reception ($t_{\text{now}}$), the laboratory reference atom vibrates at the local metric rate: $$\omega_{\text{lab}} = \omega_0 \sqrt{-g_{00}(t_{\text{now}})}$$

The experimentally observed redshift $z$ is the ratio between the reference clock and the received signal: $$1 + z \equiv \frac{\omega_{\text{lab}}}{\omega_{\text{emit}}} = \frac{\sqrt{-g_{00}(t_{\text{now}})}}{\sqrt{-g_{00}(t_{\text{emit}})}}$$

Because the potential well has shallowed, $\sqrt{-g_{00}(t_{\text{now}})} > \sqrt{-g_{00}(t_{\text{emit}})}$, and therefore $1 + z > 1$. Redshift is an observation of relative time dilation between cosmic epochs. Distant light appears redshifted because modern atomic clocks tick faster than ancient atomic clocks.

8. The General Open Problem: The Self-Consistent Dynamics of Dispersal

The qualitative deductions of this paper—the Shell Theorem category error, the shallowing of the cumulative scalar potential, the acceleration of proper time, and the local invariance theorem—are complete and mathematically closed.

However, every quantitative cosmological prediction requires a dynamical law.

Because the framework proves that the FLRW metric ansatz is internally inconsistent, it cannot import any result derived from the Friedmann equations: $$\left(\frac{\dot{a}}{a}\right)^2 \neq \frac{8\pi G}{3}\rho - \frac{kc^2}{a^2}, \quad \frac{\ddot{a}}{a} \neq -\frac{4\pi G}{3}\left(\rho + \frac{3p}{c^2}\right)$$

The framework requires its own fundamental dynamics.

8.1. Internal Consistency with General Relativity

It is vital to state clearly what this framework takes from General Relativity and what it rejects.

This framework does not reject General Relativity. It rejects the FLRW metric ansatz ($g_{00} \equiv -1$) as an unphysical coordinate restriction applied to General Relativity.

The metric coupling employed here: $$-g_{00}(\mathbf{x}, t) = f\left(\frac{|\Phi_{\text{total}}(\mathbf{x}, t)|}{c^2}\right)$$ is derived entirely from standard General Relativity: 1. The Weak-Field Limit: In the linear regime ($|\Phi|/c^2 \ll 1$), General Relativity strictly requires $f(x) \approx 1 - 2x$. This is standard Einsteinian gravity. 2. The Strong-Field Threshold: As $|\Phi|/c^2$ increases toward the compaction limit, General Relativity demands that $g_{00} \to 0$. In the exact interior Schwarzschild solution for a uniform mass sphere, the central lapse function vanishes at the Buchdahl limit ($\frac{2GM}{Rc^2} = \frac{8}{9}$): $$\sqrt{-g_{00}(0)} = \frac{3}{2}\sqrt{1 - \frac{2GM}{Rc^2}} - \frac{1}{2} \longrightarrow 0$$ This saturation threshold ($g_{00} \to 0$ as density/compaction diverges) is standard General Relativity.

The framework does not introduce alternative gravity theories, scalar-tensor modifications, or aether fields. It is a strictly internal critique of FLRW within General Relativity: it uses General Relativity’s own potential-lapse coupling to demonstrate that FLRW’s coordinate assumption $g_{00} \equiv -1$ violates the field equations when applied to an expanding mass distribution.

8.2. Formulation of the Coupled System

Let a continuous distribution of mass-energy with density $\rho(\mathbf{x}, t)$ disperse into a 3-dimensional Euclidean void. The system is governed by three coupled non-linear relations within General Relativity:

1. The Cumulative Scalar Potential:
   The potential field $\Phi_{\text{total}}$ is generated by the global mass distribution: $$\Phi_{\text{total}}(\mathbf{x}, t) = -G \int \frac{\rho(\mathbf{x}', t)}{|\mathbf{x} - \mathbf{x}'|} \, d^3\mathbf{x}'$$

2. The Relativistic Metric Coupling:
   The temporal metric component $g_{00}$ is governed by standard relativistic potential-time dilation: $$-g_{00}(\mathbf{x}, t) = f\left(\frac{|\Phi_{\text{total}}(\mathbf{x}, t)|}{c^2}\right)$$ satisfying $f(x) \approx 1 - 2x$ for $x \ll 1$, and $f(x) \to 0$ at the relativistic compaction threshold.

3. The Conservation of Stress-Energy:
   The physical trajectory of the dispersing fluid is governed by the standard relativistic conservation law: $$\nabla_\mu T^{\mu\nu} = 0$$ where the 4-velocity $u^\mu = dx^\mu / d\tau$ explicitly incorporates the dynamic lapse function $\sqrt{-g_{00}}$.

8.3. The Undetermined Quantitative Ledger

Until this coupled system is solved from first principles (analytically or numerically), the following quantities remain formally undetermined:

1. The Density Trajectory $\rho(t)$: The physical dispersal rate of matter expanding under a metric where the internal clock rate is itself accelerating.
2. The Temporal Metric Lapse $g_{00}(t)$: The exact functional evolution of the cosmic clock baseline from the high-density origin to the present epoch.
3. The Dynamical Action Integral ($N_{\text{dyn}}$): Whether the physical interaction cycles diverge ($n \ge 2$) or converge ($n < 2$), which dictates the validity of the JWST and Horizon resolutions.
4. The Luminosity Distance Relation $d_L(z)$: The quantitative path of null geodesics through this dynamic lapse field: $$d_L(z) = (1 + z) \int_{t(z)}^{t_0} \frac{c}{\sqrt{-g_{00}(t')}} \, dt'$$ Whether this curve naturally produces the positive second-order curvature ($+0.775 z^2$) observed in Type Ia Supernovae without Dark Energy ($\Lambda$) can only be answered by solving this system.

8.4. The Epistemic Boundary

The distinction between the qualitative critique and the quantitative model is absolute:

• What is Proven:
  FLRW cosmology is built on an unphysical metric ansatz. Holding $g_{00} \equiv -1$ in an expanding mass distribution violates the Shell Theorem and General Relativity. The potential must shallow; the clock must accelerate; the local observer cannot detect it; and redshift is a metric clock ratio.
• What is Open:
  The specific quantitative trajectories $\rho(t)$, $g_{00}(t)$, and $d_L(z)$.

The audit does not claim to have solved the universe’s equations of motion; it demonstrates that modern cosmology has been solving the wrong equations by freezing the temporal metric.

9. Demarcation from Timescape Cosmology (Wiltshire)

Because this paper links gravitational potential to cosmic clock rates, it must be formally distinguished from David Wiltshire’s Timescape Cosmology (2007–2014).

Feature	Timescape Cosmology (Wiltshire)	Shallowing Potential Audit (Rogers)
Theoretical Foundation	Internal to GR (Inhomogeneous): Uses Buchert’s averaging formalism of Einstein’s equations.	Internal to GR (Homogeneous): Uses relativistic potential-time coupling against FLRW’s coordinate ansatz.
Perturbative Order	First-Order: Operates on the contrast between overdense halos and underdense voids.	Zero-Order: Operates on the cumulative potential of the cosmic mass distribution as a whole.
Status of $g_{00}$	Retains $g_{00} = -1$ Globally: Assumes an unvarying Einstein-de Sitter background for volume-averaged space.	Rejects $g_{00} = -1$ Universally: Proves that an expanding mass distribution cannot possess static $g_{00}$ even if perfectly smooth.
Mechanism of Redshift	Expansion + Variance: Traditional spatial expansion supplemented by differential clock drift between structures.	Pure Potential Ratio: Redshift is the direct ratio of clock tick rates between epochs in a shallowing well.
Epoch of Action	Late Universe Only ($z < 1$): Effects only emerge after voids form and dominate cosmic volume.	All Epochs ($z \to \infty$): Operates continuously across all cosmic history.
High-$z$ Anomalies	Cannot Resolve JWST: At $z > 10$, density perturbations were tiny ($\delta\rho/\rho \sim 10^{-5}$); void contrast vanishes.	Conditional Resolution of JWST: Depends on the divergence of $N_{\text{dyn}}$ as $\rho \to \infty$.

Wiltshire accepts the standard FLRW assumption that a smooth, homogeneous universe has an invariant clock rate ($g_{00} \equiv -1$), attributing cosmological anomalies entirely to late-time structure formation.

The Shallowing Potential Audit demonstrates that the homogeneous background metric itself is invalid within General Relativity. Even if the universe were completely devoid of voids and clusters, the dispersal of matter mathematically forces the scalar potential to shallow, accelerating the zero-order rate of time.

10. Conclusion

The foundational architecture of modern cosmology has rested on an unexamined assumption for a century: that time can be held static while space expands.

The deductive steps proven in this paper are: 1. Spatial symmetry cancels gravitational force vectors ($\nabla \Phi = \mathbf{0}$), but scalar potentials accumulate. The assumption that $\nabla \Phi = \mathbf{0}$ permits setting $g_{00} \equiv -1$ is a foundational category error. 2. An expanding mass distribution forces the cumulative scalar potential well to shallow monotonically over time ($\frac{d}{dt}|\Phi_{\text{total}}| < 0$). 3. In General Relativity, a shallowing potential well forces the rate of proper time to accelerate ($\frac{d}{dt}(d\tau/dt) > 0$). Holding $g_{00} = -1$ in an expanding metric is an internal self-contradiction. 4. Observers cannot detect this acceleration locally because the metric lapse cancels identically out of every internal measurement ratio (The Local Invariance Theorem). 5. Cosmological redshift is the natural observation of this metric evolution: $1+z$ is the relative frequency ratio between a slow primeval clock and a fast modern clock.

We have isolated the frontier: The quantitative fate of modern cosmology—the explanation of Type Ia Supernova dimming without Dark Energy, the resolution of the JWST early-galaxy crisis, and the elimination of the Horizon Problem—hangs entirely on solving the self-consistent equations of motion for a dispersing mass distribution coupled to its own cumulative scalar potential within General Relativity.

By acknowledging this boundary, the framework adopts an unassailable epistemic position: it does not replace General Relativity; it uses General Relativity to purge an unphysical coordinate ansatz, proves the qualitative necessity of an accelerating clock, and clearly defines the exact mathematical problem that theoretical physics must solve next.
