The Worldline as Unification: A Relational Perspective on Fundamental Physics

 


Abstract:

This paper proposes a conceptual framework for understanding fundamental physics based on the principle of 1:1 correspondence between frequency, mass, energy, momentum, and spacetime curvature. We argue that these seemingly disparate quantities are different manifestations of the same underlying reality, embodied by the worldline of a particle. This is the interaction of the particle with spacetime. By reinterpreting Planck's constant and the gravitational constant in terms of a fundamental mass-time constant (Q_m) and a "fundamental frequency of gravity" (f_d), we show how the core equations of quantum mechanics and relativity can be seen as expressions of this underlying unity. This perspective suggests that the worldline, representing the dynamic interaction ("dance") between a particle and spacetime, is the fundamental entity, offering a potential pathway towards a relational and unified view of physics, potentially bridging the gap between quantum mechanics and General Relativity. This is not a new theory, but a reinterpretation of existing physics, emphasizing inherent, but often overlooked, relationships.

1. Introduction

The history of physics has been marked by a quest for unification – the search for a single, underlying principle or framework that can explain the diverse phenomena of the universe. Major milestones include Newton's unification of terrestrial and celestial mechanics, Maxwell's unification of electricity and magnetism, and Einstein's unification of space and time, and mass and energy. However, a complete unification, particularly one that bridges the gap between General Relativity (GR) and Quantum Mechanics (QM), remains an elusive goal.

This paper proposes a conceptual framework for unification based on a relational perspective, where the fundamental entity is not a particle or a field, but the worldline of a particle – the particle's  4-dimensional path through spacetime. We argue that the seemingly disparate physical quantities of frequency, mass, energy, momentum, and spacetime curvature are not independent entities, but different manifestations of the same underlying reality, all directly proportional to each other and embodied in the worldline. This 1:1 correspondence, often obscured by our conventional choice of units and the way we write physical equations, is, we argue, the key to a deeper understanding of fundamental physics.

2. The 1:1 Correspondence Principle

Our core principle is the 1:1 correspondence between frequency (f), mass (m), gravity (G), energy (E), momentum (p), inverse wavelength, and spacetime curvature. This correspondence is not mediated by frequency; frequency is simply one manifestation of the underlying unified quantity. The others are equally valid representations.

This principle can be expressed, in appropriate units (where c = 1 and the kilogram is redefined so that Q_m = 1, as discussed below), as having the identical numerical values:

  • m ∝ f

  • E ∝ f

  • p ∝ f

  • Curvature ∝ f

  • 1/wavelength  = f

These proportionalities are not new physics; they are inherent in the existing equations of Q_m and relativity, such as E = hf, E = mc², and the de Broglie wavelength (p = h/λ). However, the directness and fundamental nature of these relationships are often overlooked.

3. Redefining the Constants: Q_m and f_d

To make the 1:1 correspondence explicit, we introduce two key quantities:

  • Q_m (Mass-Time Constant): Defined as the mass-energy equivalent of a 1 Hz photon, divided by c². This represents the fundamental proportionality constant between mass and frequency:

    m = Q_m * f (Equation 1)

    This equation is the mathematical cornerstone of our framework. It states that mass is fundamentally a manifestation of frequency.  You can get the value and units of Q_m with

    Q_m = h/

  • f_d ("Fundamental Frequency of Gravity"): This represents the "frequency of gravity" associated with a specific reference gravitational configuration (where m1 * m2 / r² = 1, in appropriate units). It's not a universal constant, but a reference value that scales with the gravitational interaction. We define its relationship to conventional constants as:

    f_d = G / (h/c)  (Equation 2)

    This definition is chosen for dimensional consistency within our framework, recognizing that the conventional units of G incorporate a scaling factor related to the Newtonian force law.

  • G becomes just a simple force default formula that carries extra units to make m1m2/r^2 unit-less.  G= Q_m * f_d * c  

4. Reinterpreting 

With Q_m and f_d, we can reinterpret Planck's constant (h) and the gravitational constant (G):

  • h = Q_m * c² (Equation 3)

    This shows that h is not a fundamental constant, but a composite quantity representing the two-step conversion from frequency to mass (via Q_m) and from mass to energy (via c²). It is a "precomputed" conversion factor.

  • G = Q_m * f_d * c (Equation 4) (with the understanding that G retains its conventional units in the Newtonian force law for dimensional consistency)  These extra units are just present to render m1m2/r^2 dimensionless. 

    This expresses G in terms of our fundamental quantities. It highlights that G, like h, is not a fundamental constant, but is related to a fundamental force-like quantity (Q_m * f_d * c) that represents the basic interaction between a particle's worldline and spacetime. The conventional units of G are understood as arising from its role in scaling this fundamental force to macroscopic scenarios in the Newtonian framework.

5. The Worldline as Unification

The worldline of a particle is not simply a trajectory through spacetime; it is the fundamental entity that embodies the 1:1 correspondence. The worldline's properties (its "length," its "direction," its intrinsic "oscillation") define the particle's mass, energy, momentum, frequency, and its contribution to spacetime curvature.

  • Frequency: The worldline's intrinsic "oscillation" or periodicity manifests as frequency.

  • Mass-Energy: The worldline's "length" or invariant interval in spacetime manifests as mass-energy.

  • Momentum: The worldline's "direction" in spacetime manifests as momentum.

  • Curvature: The worldline's interaction with other worldlines determines the curvature of spacetime. This interaction is governed by the fundamental force related to G (Q_m * f_d * c).

  • Inverse wavelength: The direct length that corresponds to its mass and frequency

The worldline is thus the "dance" between the particle and spacetime, a dynamic and reciprocal relationship where the particle's properties and the geometry of spacetime are mutually defined.

6. Implications for Quantum Gravity

This framework suggests a novel approach to quantum gravity:

  • Inherent Quantization: Because frequency is quantized, and all other quantities are directly proportional to frequency, mass, energy, momentum, and spacetime curvature are also inherently quantized. The quantization of frequency is the quantization of gravity.

  • Worldline Quantization: The fundamental "quantum" is not a particle or a field, but a quantized worldline. Quantum gravity, in this view, would be a theory of quantized worldlines.

  • No Separate "Graviton": This framework doesn't necessarily require a separate "graviton" particle as a mediator of gravity. The gravitational interaction is inherent in the 1:1 correspondence and the dynamic interplay of worldlines. Space time is curved, not a force, so no particle needed to mediate it. 

8. Conclusion

The framework presented here, based on the 1:1 correspondence principle and the centrality of the worldline, offers a potentially unifying perspective on fundamental physics. By reinterpreting Planck's constant and the gravitational constant, and by emphasizing the inherent interconnectedness of frequency, mass, energy, momentum, and curvature, we suggest that the unification of quantum mechanics and General Relativity may lie not in finding new equations or particles, but in recognizing the profound unity that already exists, hidden within the structure of existing physics, and embodied in the dynamic interplay of worldlines. This is a relational view of physics, where the properties of particles and the geometry of spacetime are mutually and dynamically defined, with frequency serving as a key manifestation of this underlying unity. This paper proposes that the "dance" of the worldline is the unification.
