The Unifying Theory (UT) proposes a transformative approach to unifying quantum mechanics and classical physics by redefining motion as discrete jumps. Each jump is defined by two temporal parameters: a brief jump duration and a "linger time" denoting the pause between successive jumps. The theory postulates two motion regimes: stochastic jumps with zero linger time, spanning the wave function’s spatial extent and producing quantum interference patterns; and deterministic jumps at fixed distances (the de Broglie wavelength λ_dB) with non-zero linger time, yielding classical behavior. The transition between regimes is triggered by measurement-induced entanglement with a measurement system—a process where quantum systems entangle with detectors, altering their jump dynamics from stochastic to deterministic, thus providing a physical mechanism for wave function collapse. UT also explains length contraction by incorporating relativistic effects through a dilated jump time t_p^'=t_p/√(1-v^2/c^2 ),. Finally, UT offers testable predictions, including distinct electron scattering angles of ~0.05° on crystalline surfaces when the de Broglie wavelength matches lattice spacing—testable with existing electron microscopy techniques. Unlike current approaches that treat quantum and classical physics as separate domains, UT provides a unified framework with concrete experimental signatures.
