Higgs Field as Architect of a Geodesically Complete Universe and Agent for New Physics in Interiors of Black Holes

This paper proposes that the Higgs field acts as a non-perturbative agent near gravitational singularities to generate antigravity regions and restore electroweak symmetry, thereby creating a geodesically complete universe with traversable singularities that offers a unitary resolution to the black hole information paradox.

Imagine the universe as a vast, calm ocean. In our current understanding of physics, the Higgs Field is like the water itself—a gentle, invisible ocean that fills all of space. Particles swim through it, and the more they interact with the water, the heavier they become. This is the standard story: the Higgs gives mass, and gravity pulls things together.

But in this new paper, physicist Itzhak Bars suggests the Higgs field is actually the architect of a much stranger, more complete universe. He proposes that near the most extreme places in the cosmos—like the center of a black hole or the moment of the Big Bang—the Higgs field doesn't just give mass; it flips the script entirely.

Here is the story of this new universe, explained simply:

1. The Problem: The "Dead End" in the Road

In our current physics (General Relativity), if you fall into a black hole, you eventually hit the center, called a singularity. It's a point of infinite density where the laws of physics break down.

The Analogy: Imagine driving a car on a highway that suddenly ends at a sheer cliff. You know you will fall, but the map (our current physics) has no instructions for what happens after you fall off the edge. The road just stops. This is called "geodesic incompleteness"—the path of a particle simply vanishes.

2. The Solution: The "Gravity Switch"

Bars argues that the Higgs field acts like a universal switch that can flip gravity from "pulling" to "pushing."

The Mechanism: The strength of gravity isn't a fixed number; it depends on the Higgs field.
- Normal Gravity (Our World): The Higgs field is in a state where gravity pulls things together (like a magnet).
- Antigravity (The New Zone): Deep inside a black hole, the Higgs field changes its state. Suddenly, gravity flips and starts pushing things apart.
The Result: Instead of hitting a dead-end cliff, the road doesn't stop. It curves around and leads into a new region where gravity is reversed. The singularity isn't a wall; it's a bridge.

3. The Journey: Crossing the Bridge

Imagine falling into a black hole in this new universe:

The Descent: You fall through the event horizon (the point of no return).
The Flip: As you approach the center, the Higgs field triggers the switch. Gravity turns into antigravity.
The Crossing: You don't get crushed. Instead, you pass through the singularity. It's like walking through a door that leads to a mirror world.
The Other Side: You emerge into a region where gravity pushes you away. This region is mathematically connected to the "outside" of the universe, but it's a different domain.

4. The Big Surprise: Mass Vanishes

Here is the most magical part. In our world, the Higgs field gives particles their mass (like water making it hard to swim).

At the Singularity: The Higgs field drops to zero.
The Effect: All massive particles (electrons, protons, you) suddenly become massless. They turn into pure energy, like light.
Why it matters: Because they have no mass, they can pass through the "bridge" (the singularity) without getting stuck. It's like a heavy truck turning into a beam of light to fly through a tunnel.

5. Solving the Black Hole Mystery

For decades, physicists have been worried about the Black Hole Information Paradox.

The Old Problem: If you throw a book into a black hole, and the black hole evaporates, does the story in the book disappear forever? If yes, physics breaks because information cannot be destroyed.
The New Answer: The book doesn't disappear. It travels through the singularity bridge into the antigravity region.
- The information is not lost; it's just moved to a different part of the universe that we can't see from the outside.
- Because the universe is now a complete loop (a bridge connecting gravity and antigravity), nothing is ever truly lost. The "accounting" of the universe balances out.

6. The "Mirror Box" Analogy

To visualize the whole structure, imagine the universe as a giant, infinite hallway.

Gravity Side: You are in a room where the floor pulls you down.
The Singularity: This is a special door in the middle of the hallway.
Antigravity Side: Behind the door is a room where the floor pushes you up.
The Connection: The door is always open. If you walk through it, you don't fall off the edge of the world; you just enter a new room where the rules are flipped. The hallway continues forever in both directions.

Why This Matters

This theory suggests that the Higgs field is not just a "mass-giver" but the architect of reality's structure. It turns the scary, broken places in the universe (singularities) into safe, traversable bridges.

For Black Holes: They aren't cosmic trash compactors; they are portals to a hidden, antigravity sector of the universe.
For the Big Bang: The same mechanism might explain how our universe began, suggesting the Big Bang was a transition from an antigravity state to our current gravity state.
For Us: It means the universe is "complete." There are no dead ends, no places where physics stops working. The story of the universe is continuous, connected, and safe.

In short, Bars is telling us that the Higgs field is the glue that stitches the broken pieces of the universe together, turning the terrifying "end of the road" into a new beginning.

1. The Fundamental Problem

The paper addresses the geodesic incompleteness inherent in the Standard Model (SM) coupled with General Relativity (GR).

The Issue: In traditional $(SM+GR)$, spacetime singularities (e.g., the center of a black hole at $r=0$ or the Big Bang) act as boundaries where geodesics (particle trajectories) terminate. An external observer sees time $t$ diverge at the horizon, but a falling particle reaches $r=0$ in finite proper time $\tau$ . The theory provides no prescription for the particle's state or trajectory beyond this point.
Limitations of Current Solutions: Existing quantum gravity approaches (including String Theory) often introduce background fields that are themselves incomplete or obscure the issue via non-geometric models. They fail to resolve what happens at or beyond the singularity.
Root Cause: The author identifies the absence of antigravity domains (where the gravitational strength $G < 0$ ) in traditional formulations as the root cause of this incompleteness.

2. Methodology and Theoretical Framework

The paper proposes a resolution using an improved version of the Standard Model coupled to GR, denoted as $i(SM+GR)$.

Local Scale Invariance (Conformal Symmetry): The theory is built on local scale invariance, where dimensionful constants are forbidden. All scales emerge dynamically from scalar fields.
The Action: The Lagrangian includes the SM fields, a Higgs doublet ( $H$ ), and an additional scalar singlet ( $\phi$ ). Crucially, gravity couples non-minimally to these scalars with a conformal coupling coefficient of $1/12$ :
$\mathcal{L} \supset \frac{1}{12}(\phi^2 - 2H^\dagger H)R(g)$
Dynamical Gravitational Strength: The Newton constant is replaced by a dynamical field $G(x)$ :
$(16\pi G(x))^{-1} \equiv \frac{\phi^2}{12} \left(1 - h^2\right), \quad \text{where } h^2 \equiv \frac{2H^\dagger H}{\phi^2}$
The Mechanism: The factor $(1 - h^2)$ $(1 - h^{2})$ can change signs depending on the spacetime location $x^\mu$ $x^{μ}$ .
- Gravity Region: $h^2 < 1 \implies G(x) > 0$ .
- Antigravity Region: $h^2 > 1 \implies G(x) < 0$ .
- Singularity: $h^2 = 1$ , where $G(x)$ diverges, acting as the boundary between the two domains.
Unitarity: Although the relative minus sign in the kinetic terms suggests a "ghost" field, the local scale symmetry compensates for this, preserving unitarity. The theory is formulated in a 4+2 dimensional framework (2T-physics) where scale transformations have a geometric origin.

3. Key Contributions and Results

A. Geodesic Completeness via Traversable Singularities

The theory unifies gravity and antigravity regions into a single, geodesically complete spacetime.

Traversable Singularities: The singularity at $r=0$ (where $h^2=1$ ) is not a dead end but a traversable bridge.
Coordinate Extension: The author introduces a new radial coordinate $r$ $r$ that spans $(-\infty, +\infty)$ $(- \infty, + \infty)$ .
- $r > 0$ : Gravity domain (Standard Schwarzschild-de Sitter).
- $r < 0$ : Antigravity domain (Negative-mass Schwarzschild-anti-de Sitter).
- $r = 0$ : The traversable singularity.
Kruskal-Szekeres (KS) Extension: The maximal extension of the spacetime includes previously discarded regions ($V, VI$) which now correspond to the antigravity domain ( $r < 0$ ). The singularity ($uv=1$) becomes a seamless junction.

B. The AdSSdS Black Hole Geometry

The paper derives a static, spherically symmetric metric describing an AdSSdS (Anti-de Sitter / Schwarzschild / de Sitter) Black Hole:
$ds^2 = -dt^2 A(r) + \frac{1}{A(r)}dr^2 + r^2 d\Omega^2$

Asymptotics:
- $r \to +\infty$ : Asymptotically de Sitter (our observable universe).
- $r \to -\infty$ : Asymptotically Anti-de Sitter (antigravity region).
Horizons: The geometry possesses both a black hole horizon ( $r_h$ ) and a cosmological horizon ( $r_c$ ).
Penrose Diagram: The resulting Penrose diagram is fully causal and complete. It shows that geodesics can cross the singularity, enter the antigravity region, reflect off the AdS boundary (acting like a mirror), and re-enter the gravity region or other universes.

C. Electroweak Symmetry Restoration

A critical result concerns the behavior of the Higgs field ( $s$ ) and the scalar singlet ( $\phi$ ) at the singularity.

The "Red Curve" Solution: Analysis of the coupled field equations reveals a dominant solution where both scalars vanish at the singularity: $\phi(0) = s(0) = 0$ .
Symmetry Restoration: Since particle masses in the SM are generated by the Higgs VEV ( $s$ ), the vanishing of $s(0)$ implies the restoration of $SU(2) \times U(1)$ electroweak symmetry at the black hole singularity.
Consequence: All massive particles become massless at the singularity, allowing them to traverse the barrier (similar to massless particles) without being blocked by an effective potential wall.

D. Resolution of the Black Hole Information Paradox

The paper proposes a new resolution to the information paradox based on global unitarity:

Information Flow: Information falling into a black hole is not lost; it is transferred to the antigravity domain ( $r < 0$ ) and potentially to other regions of the complete spacetime.
Unitarity: Quantum unitarity is preserved if defined with respect to all observers in the complete universe (including those in the antigravity region), not just those in the visible gravity region.
Bidirectional Flow: Information can flow bidirectionally between gravity and antigravity regions via massless particles (photons, gravitons) and potentially via quantum tunneling for massive particles.

4. Significance and Implications

New Physics in Black Hole Interiors: The interior of a black hole is not a region of infinite density and zero volume but a gateway to an antigravity universe with negative curvature (AdS).
Phenomenological Predictions:
- Cosmology: The mechanism applies to the Big Bang, suggesting a bounce or transition from an antigravity phase.
- Observational Tests: Modifications to the metric $g_{\mu\nu}(r)$ near the horizon could alter curvature outside the black hole. This might influence galactic rotation curves or gravitational lensing, potentially offering an alternative or supplement to Dark Matter explanations.
Theoretical Unification: The work bridges the gap between the Standard Model and Gravity by treating the Higgs field not just as a mass generator, but as the architect of spacetime topology, enabling the existence of antigravity domains.
String Theory Connection: The framework is compatible with string theory generalizations (referenced as [6]), suggesting a path toward a geodesically complete quantum theory of gravity.

Conclusion

Itzhak Bars argues that by extending the Standard Model with local scale invariance and allowing the gravitational coupling to become negative (antigravity), the universe becomes geodesically complete. Singularities are reinterpreted as traversable bridges connecting gravity and antigravity domains. This framework naturally resolves the black hole information paradox by ensuring information is conserved globally across the unified spacetime, while simultaneously predicting the restoration of electroweak symmetry at the singularity.
