Sphere Theory: A New Path to Quantum Gravity, No Extra Dimensions or Supersymmetry Needed
For decades, we've been told that solving quantum gravity requires radical new ideas like extra dimensions (String Theory) or quantizing spacetime itself (LQG). But what if the solution is simpler and has been hiding in plain sight within General Relativity all along?
Sphere Theory is a framework built on one core principle: The source of gravity isn't just an object's free-state mass, but its total energy, which must include its own negative gravitational self-energy.
Why 'Sphere Theory'?
As an object becomes more compact, its negative self-energy grows. My paper shows there is a critical radius, R_gs, where this negative energy perfectly cancels the object's positive mass-energy (Mc^2), bringing its total energy to zero. This critical radius can be derived from Newtonian physics as:
|Gravitational Self-Energy| = Mass-Energy
Solving for the radius gives us this critical radius
R_gs = (3/5)GM/c^2
(*For the detailed calculation based on general relativity, please refer to the paper.)
If the object were to shrink further (R<R_gs), it would enter a negative energy state. This generates a repulsive gravitational force ('anti-gravity'), which prevents any further collapse.
Therefore, R_gs acts as an minimal radius. Nothing can be stably smaller. (This is temporarily possible, however.) This replaces the abstract 'point' particle with a fundamental, volumetric 'sphere'.
How is this different from String Theory?
Crucially, Sphere Theory is Testable
This framework makes concrete, falsifiable predictions that distinguish it from standard theories:
1. A Falsifiable Prediction at the Planck Scale: It predicts a novel "quantum-dominant regime." Standard Effective Field Theory (EFT) predicts that as you approach the Planck scale, classical GR corrections will always overwhelmingly dominate quantum corrections. My paper shows the ratio of these corrections is approximately V_GR / V_Q ≈ 4.66 * (M/M_P) * (r/ l_P). For a stellar-mass black hole, this ratio is a staggering ~10^39, making quantum effects utterly negligible.
Sphere Theory reverses this. As an object approaches its critical radius R_gs, its equivalent mass (M_eq) is suppressed, which quenches the classical correction. The quantum term, however, is not suppressed in the same way. This creates a window where quantum effects become the leading correction, a unique and falsifiable signature that distinguishes this theory from standard EFT at its point of failure.
2. At the other Scale: Offers a unified explanation for the major puzzles of modern cosmology by providing (a) a mechanism for cosmic inflation, (b) a model for the accelerated expansion of the universe, and (c) a predicted upward revision of the neutron star mass limit}, all of which serve as falsifiable tests (Chapter 7).
The reason that this can be verified even in macroscopic events is because, unlike string theory, the minimum critical radius is proportional to the mass.
I believe this approach offers a more direct, physically grounded path to a complete theory of gravity.
~~~~
It is a foundational principle, recognized in both Newtonian mechanics and general relativity, that the true gravitational source is the equivalent mass (M_eq), which includes gravitational self-energy (binding energy), rather than the free state mass (M_fr). This principle leads to a running gravitational coupling, G(k), that vanishes at a critical scale, R_gs ~ G_NM_fr/c^2. This behavior provides a powerful and self-contained mechanism for gravity’s self-renormalization, driving the coupling to a trivial (Gaussian) fixed point (G(k) -> 0) and rendering the infinite tower of EFT counter-terms unnecessary.
The scope of Sphere Theory extends far beyond the divergence problem, providing a unified foundation for several long-standing puzzles. We will demonstrate that this single principle:
1)Resolves the singularity problem via a repulsive force that emerges at a macroscopic, not quantum, scale (Chapter 2-3).
2)Solving the 2-loop or greater divergence problem: Solve the 2-loop or greater divergence problem proposed by Goroff and Sagnoti (Section 4.6.3).
3)Solves divergence problems in standard Effective Field Theory (EFT): It solves the divergence problem of the standard effective field theory (EFT) proposed by John F. Donoghue et al.(Chapter 5~6.)
4)Provides a complete, self-renormalizing framework for gravity that is consistent with the low-energy predictions of EFT, while offering a physical completion at high energies (Chapter 5-6). This includes a novel prediction of a "quantum-dominant regime" that distinguishes it from standard EFT. This provides, in principle, a unique experimental signature that could distinguish this self-renormalization model from standard EFT, should technology ever allow for probing physics at this scale.
5)Establishes the physical origin of the Planck-scale cutoff in quantum field theory (Chapter 4.7).
6) Offers a unified explanation for the major puzzles of modern cosmology by providing (a) a mechanism for cosmic inflation}, (b) a model for the accelerated expansion of the universe}, and (c) a predicted upward revision of the neutron star mass limit}, all of which serve as falsifiable tests (Chapter 7).
~~~~~~
To contextualize the contributions and philosophy of Sphere Theory, we present a direct comparison with the two other leading frameworks: Quantum Field Theory (as exemplified by the EFT of gravity) and String Theory.
7.1 Philosophical cornerstones and testable predictions
The comparative analysis presented in Table 1 highlights the unique philosophical and physical foundations of Sphere Theory. While EFT offers unparalleled experimental success in its domain and String Theory provides mathematical elegance, Sphere Theory distinguishes itself through its commitment to physical realism and logical economy. Two distinctions are particularly crucial.
7.1.1 Minimal Length: Derived, not postulated
First is the concept of minimal length. String Theory postulates a minimal length scale (l_s) as a fundamental, fixed constant of nature. In contrast, Sphere Theory derives its minimal radius R_gs from the established principles of general relativity. This minimal radius is not a universal constant but a dynamic variable, proportional to the mass-energy of the object itself:
R_gs ~ GM_fr/c^2
This provides a more fundamental and less ad-hoc explanation for why nature appears to have a physical cutoff at the Planck scale.
This inherent scalability, where the core principle operates identically at both the Planck and cosmological scales, elevates it from a mere model to a candidate for a truly fundamental principle of gravity.
7.1.2 Experimental Falsifiability: A two-scale test
Second is the criterion of experimental falsifiability, a feature that distinguishes Sphere Theory from many alternatives. This testability arises directly from the dynamic, scale-dependent nature of the theory’s central relation, which provides concrete, distinguishing predictions at two vastly different physical scales.
[ The microscopic test: The physical origin of the Planck Scale ]
At the microscopic level, this relation provides a physical origin for the Planck-scale cutoff (Refer to Chapter 4.7.). For a quantum fluctuation with the Planck mass (M_fr ~ M_P), the equation naturally yields a critical radius on the order of the Planck length:
R_gs ~ GM_fr/c^2 = GM_P/c^2 = l_P
This demonstrates how the Planck scale emerges as a natural limit, not a postulate. It also predicts the existence of a "quantum-dominant regime" near this scale, a concrete prediction that, while technologically monumental to test, grounds the theory in the scientific method. For calculations, please refer to Chapters 5 and 6.
In addition to providing a physical origin for the Planck-scale cutoff, Sphere Theory makes a novel, falsifiable prediction that distinguishes it from standard Effective Field Theory (EFT) at high energies: the existence of a "quantum-dominant regime." This phenomenon arises from the core mechanism of the theory—the renormalization of the gravitational source mass (M_fr -->M_eq).
The unified gravitational potential proposed by Sphere Theory includes both the classical General Relativistic (GR) correction and the leading quantum correction, similar to standard EFT. However, a crucial difference emerges near the critical radius (R_gs).
● Suppression of classical effects: The classical GR correction term in the potential is directly proportional to the equivalent mass (M_eq). As a particle's radius (R_m) approaches its critical radius (R_gs), its M_eq approaches zero. Consequently, the classical GR correction is strongly suppressed.
● Emergence of quantum dominance: In stark contrast, the leading quantum correction term (proportional to \hbar) is not suppressed by the equivalent mass in the same manner. This differential behavior leads to a remarkable inversion: in the transition region just before the critical radius is reached, the normally sub-dominant quantum correction becomes larger than the suppressed classical correction. This window, where quantum effects become the leading correction to the Newtonian potential, is the "quantum-dominant regime."
● Divergence from standard EFT and testability: Standard EFT, which does not incorporate the concept of equivalent mass, predicts a completely different behavior. As energy increases (or distance decreases toward the Planck scale), its classical correction terms grow uncontrollably, signaling a breakdown of the theory's predictive power. Sphere Theory, however, provides a physical completion precisely at this point of failure. The suppression of classical effects via M_eq tames the interaction and unveils the quantum-dominant regime.
This regime is not a minor artifact; it is a unique physical phenomenon predicted exclusively by Sphere Theory. While technologically monumental to probe, its existence provides, in principle, a distinct and falsifiable experimental signature that could distinguish this framework from all standard approaches to quantum gravity

#Paper: Sphere Theory: A Unified Framework for Gravity from Self-Energy
For decades, we've been told that solving quantum gravity requires radical new ideas like extra dimensions (String Theory) or quantizing spacetime itself (LQG). But what if the solution is simpler and has been hiding in plain sight within General Relativity all along?
Sphere Theory is a framework built on one core principle: The source of gravity isn't just an object's free-state mass, but its total energy, which must include its own negative gravitational self-energy.
Why 'Sphere Theory'?
As an object becomes more compact, its negative self-energy grows. My paper shows there is a critical radius, R_gs, where this negative energy perfectly cancels the object's positive mass-energy (Mc^2), bringing its total energy to zero. This critical radius can be derived from Newtonian physics as:
|Gravitational Self-Energy| = Mass-Energy
Solving for the radius gives us this critical radius
R_gs = (3/5)GM/c^2
(*For the detailed calculation based on general relativity, please refer to the paper.)
If the object were to shrink further (R<R_gs), it would enter a negative energy state. This generates a repulsive gravitational force ('anti-gravity'), which prevents any further collapse.
Therefore, R_gs acts as an minimal radius. Nothing can be stably smaller. (This is temporarily possible, however.) This replaces the abstract 'point' particle with a fundamental, volumetric 'sphere'.
How is this different from String Theory?
- Derived vs. Postulated: String Theory postulates a fixed minimal length. Sphere Theory derives a dynamic minimal radius (R_gs) that is proportional to the object's mass.
- Simplicity: It requires no extra dimensions, no supersymmetry, and no new particles. It aims to solve the problem using the physics we already have.
- Universality: This highlights another fundamental difference in scope. String Theory's central feature is its minimal length, fixed at the Planck scale. While this offers a potential resolution for divergences at that specific scale, the challenges of gravity are not confined to the microscopic. They extend to the largest cosmological scales, where String Theory offers less clear solutions. This suggests that a theory with a fixed minimal scale may not be the fundamental framework capable of describing both domains. This is where Sphere Theory offers a profoundly different and more powerful approach. Its critical radius R_gs, is not a fixed constant but a dynamic variable proportional to mass (R_gs ∝ M). This inherent scalability means the theory's core principle applies seamlessly from the smallest quantum fluctuations at the Planck scale to the entire observable universe. It therefore has the potential to be a true candidate for the ultimate solution to gravity, unifying the physics of the very small and the very large under a single, coherent principle.
