Recent experimental results have shown a violation of Bell’s inequalities, which are a mathematical formulation of Einstein-Podolsky-Rosen (EPR) paradox. The violation leads to the conclusion that there are no local hidden variable theories that underlie quantum mechanics. However, the Bell’s inequalities do not rule out the possibility to construct non-local hidden variable theories that comply with quantum mechanics, in particular, a theory of special and general relativity that permits an instantaneous transmission of interaction. In this work we show that a special relativity with a Euclidean metric that allows not only local interactions but also interactions that can be transmitted instantaneously can be constructed and, furthermore, such special relativity can also be generalised to formulate a general theory of relativity that leads to the same experimental results as Einstein theory of general relativity. We also show that it is possible to formulate Dirac-like relativistic wave equations in this Euclidean relativity with either real mass or imaginary mass, which suggests that the proper mass of a quantum particle may be defined in terms of a differential operator that is associated with a spacetime substructure of the particle.
The classical equations of motion of a charged point-particle with intrinsic spin under the influence of an external electromagnetic field are restated and compared with the Heisenberg equations of motion derived from the Dirac theory. The partition of angular momentum between particle and field in the classical theory is contrasted to the Dirac theory of electron spin. The analogy between the Dirac equation and the theory of parametric amplification is pointed out.A free spinning point particle moving according to the laws of classical relativistic point-particle mechanics may move along a helix. The sum of the intrinsic spin $\ensuremath{\sigma}$ and the angular momentum of the helical motion in this classical analog of zitterbewegung is an effective spin vector S which is a constant of the motion. Because of this internal motion, the effective mass
M of the particle differs from the mass
m which is ascribed to it in the equations of motion. Solutions are found in which S is parallel or antiparallel to the momentum, and the sign of
M is determined by the helicity. When placed in a uniform electromagnetic field, the particle behaves as if it had a rest mass
M and a magnetic moment $\frac{e\ensuremath{\sigma}}{\mathrm{Mc}}$, in addition to any explicit magnetic moment that may be ascribed to it.
This paper proposes a new interpretation of one of the foundational equations of modern physics. Rather than treating the Dirac equation as the microscopic engine of the universe, it argues that the Dirac spinor is the observer-level readout of a deeper second-order computational substrate. Building on previous Lattice Field Medium (LFM) research establishing the emergence of a stable electron from the governing substrate equations, this work asks the next logical question: once an electron has formed, how does the familiar Dirac equation emerge? The paper introduces three new concepts: • Observer Compression Theorem — demonstrating that observers embedded within a local causal computational substrate cannot directly access the complete microscopic state and must necessarily describe physics through a compressed observer-accessible quotient. • Readout Operator — an explicit mathematical mapping from the full two-frame LFM lattice state to the four-component Dirac spinor by extracting observer-accessible quantities including momentum, effective mass, spin, helicity, phase, and particle/antiparticle branch information. • Minimal Readout Theorem — proving that any observer-level description reproducing one-electron Dirac observables must recover the same invariant physical quantities, establishing the minimal information required for relativistic electron dynamics. The paper further demonstrates that repeated application of the Readout Operator to the evolving second-order substrate reproduces Dirac evolution in the local continuum limit while preserving the standard predictive success of relativistic quantum mechanics. Numerical readout diagnostics validate the construction through controlled benchmark tests, including near-machine-precision one-step Dirac fidelity, exact branch recovery, spin-precession agreement, and information compression exceeding four orders of magnitude while maintaining high reconstruction fidelity. This work does not replace the Dirac equation. Instead, it proposes a deeper computational interpretation in which Dirac theory remains the correct observer-level description while emerging naturally from a richer second-order substrate. More broadly, it introduces an information-theoretic hierarchy separating microscopic computation from observer-accessible physics, providing a new framework for understanding why first-order quantum equations arise from deeper computational dynamics.
