Probabilistic description of results of measurements and its consequences for understanding quantum mechanics are discussed. It is shown that the basic mathematical structure of quantum mechanics like the probability amplitudes, Born rule, probability density current, commutation and uncertainty relations, momentum operator, rules for including scalar and vector potentials and antiparticles can be derived from the definition of the mean values of powers of space coordinates and time. Equations of motion of quantum mechanics, the Klein-Gordon equation, Schrödinger equation and Dirac equation are obtained from the requirement of the relativistic invariance of the theory. The limit case of localized probability densities leads to the Hamilton-Jacobi equation of classical mechanics. Many-particle systems are also discussed.
A type of mechanics will be presented that possesses some distinctive properties. On the one hand, its physical description & rules of operation are readily comprehensible & intuitively clear. On the other, it fully satisfies all observable predictions of non-relativistic quantum mechanics. Within it, particles exist at points in space, follow continuous, piecewise differentiable paths, and their linear momentum is equal to their mass times their velocity along their path. Yet the probabilities for position and momentum, conditioned on the state of the particle's environment, follow the rules of quantum theory. Indeed, all observable consequences of quantum theory are satisfied; particles can be entangled, have intrinsic spin, this spin is not local to the particle, particle identity can effect probabilities, and so forth. All the rules of quantum mechanics are obeyed, and all arise in a straightforward fashion. After this is established, connections will be drawn out between this type of mechanics and other types of quantum worlds; those that obey Bohmian mechanics, stochastic mechanics, the many worlds interpretation, and physical collapse. In the final section, a relativistic version of the mechanics will be presented.
The wave-particle duality is a fundamental property of the nature. At the same time, it is one of the greatest mysteries of modern physics. This gave rise to a whole direction in quantum physics - the interpretation of quantum mechanics. The Wiener experiments demonstrating the wave-particle duality of light are discussed. It is shown that almost all interpretations of quantum mechanics allow explaining the double-slit experiments, but are powerless to explain the Wiener experiments. The reason of the paradox, associated with the wave-particle duality is analyzed. The quantum theory consists of two independent parts: (i) the dynamic equations describing the behavior of a quantum object (for example, the Schrodinger or Maxwell equations), and (ii) the Born’s rule, the relation between the wave function and the probability of finding the particle at a given point. It is shown that precisely the Born’s rule results in paradox in explaining the wave-particle duality. In order to eliminate this paradox, we propose a new rational interpretation of the wave-particle duality and associated new rule, connecting the corpuscular and wave properties of quantum objects. It is shown that this new rational interpretation of the wave-particle duality allows using the classic images of particle and wave in explaining the quantum mechanical and optical phenomena, does not result in paradox in explaining the doubleslit experiments and Wiener experiments, and does not contradict to the modern quantum mechanical concepts. It is shown that the Born’s rule follows immediately from proposed new rules as an approximation.
Geometric Derivation of Quantum Mechanics from a 5D Time-Delay Manifold This paper introduces the "Time-Delay Field" (TDF) theory, a novel geometric framework that derives the fundamental equations of quantum mechanics from a deterministic five-dimensional spacetime structure. By treating the fifth dimension as an intrinsic "delay" coordinate (
τ), we demonstrate that quantum behaviors—such as superposition and interference—are projections of continuous 5D null geodesics onto our 4D reality. Abstract:We present a geometric derivation of quantum mechanics based on the TDF theory. Extending the spacetime manifold to five dimensions (
M4×S1), where the fifth dimension
τ represents an intrinsic time delay, we postulate that all fundamental particles travel on null geodesics in the 5D bulk. We demonstrate that the rest mass of a particle arises from its momentum component in the delay dimension, leading to a helical trajectory. The quantum wave function
ψ(x,t) is derived not as a probability amplitude, but as the Fourier projection of this 5D trajectory onto the 4D hypersurface. This framework rigorously recovers the Klein-Gordon and Schrödinger equations and provides a deterministic, geometric explanation for quantum interference and wave-particle duality. Furthermore, we address the measurement problem as a momentum transfer in the
τ-dimension and discuss consistency with recent experimental observations of symmetry-dependent quantum timing [Guo et al., 2026]. Key Contributions: Derivation of the Schrödinger Equation: Proves that the non-relativistic wave equation emerges naturally from the projection of 5D null paths. Resolution of Wave-Particle Duality: Explains wave-like interference as a topological phase accumulation (Moiré pattern) of helical trajectories. Objective Collapse Mechanism: Defines "measurement" as a momentum transfer in the delay dimension, eliminating the need for an observer. Mass-Dependent Decoherence: Introduces the "Quantumness Factor" (
Q), predicting an intrinsic transition from quantum to classical behavior for macroscopic masses. Experimental Alignment: Consistent with recent findings on geometry-dependent time delays in attosecond physics. Keywords: Quantum Foundations, Time-Delay Field, 5D Spacetime, Null Geodesics, Kaluza-Klein Theory, Measurement Problem, Emergent Quantum Mechanics, Geometric Phase.
In this paper, we will see that we can reformulate the purely classical probability theory, using similar language to the one used in quantum mechanics. This leads us to reformulate quantum mechanics itself using this different way of understanding probability theory, which in turn will yield a new interpretation of quantum mechanics. In this reformulation, we still prove the existence of none classical phenomena of quantum mechanics, such as quantum superposition, quantum entanglement, the uncertainty principle and the collapse of the wave packet. But, here, we provide a different interpretation of these phenomena of how it is used to be understood in quantum physics. The advantages of this formulation and interpretation are that it induces the same experimental results, solves the measurement problem, and reduces the number of axioms in quantum mechanics. Besides, it suggests that we can use new types of Q-bits which are more easily to manipulate.
The Schr?dinger differential equation is what we usually solve for the microscopic particles in non-relativistic quantum mechanics. Niels Bohr suggested the power two of the (usually) complex answer shows the probability of the particle’s existence at a point of space. Also, the time dependence of Schrodinger wave equation is one whereas for light in electromagnetism is two. In this paper, we show a solution for both problems. We derive a Wave Equation for the energy of every system. This electromagnetic wave equation is shown to convert to those classical (i.e. the Schrodinger) and special relativistic (i.e. Klein-Gordon) quantum mechanical equations. Also, accordingly there definitely is a physical meaning to answer to this wave equation. And therefore, switching the probabilistic interpretation of quantum mechanics to a deterministic one as (Albert) Einstein demanded.
