We present a hypothetical approach to the double-slit problem within the unified field theory (UFT) previously proposed by the author, in which interference and measurement are described without assuming the quantum-mechanical duality of particle and wave. In the UFT, the force is given by F = −H × M2/Mp, where H is the unified energy function. For two photons, H = 0 and the force vanishes (equilibrium). Between a photon and a slit wall, however, Hnon-self ̸= 0 and a finite non-equilibrium force arises. Defining the deflection angle by θ = −H/FPl, where FPl is the Planck force, a photon passing through the slit experiences different 1/r forces from the left and right walls depending on its transverse position, and is dispersed radially. The statistical distribution of θi over many photons may reproduce the interference pattern on the screen. Furthermore, when a detector is placed at the slit, a new non-equilibrium force arises between the photon and the detector, disturbing the radial dispersion and destroying the interference pattern. This is a deterministic picture that explains the disappearance of interference upon measurement without invoking wave- function collapse or the complementarity principle. This paper presents a hypothesis and specifies experimental tests.
We present a hypothetical approach to the formation of double-slit interference fringes and their disappearance upon measurement within the unified field theory (UFT) previously proposed by the author, without assuming particle–wave duality. In the UFT, the force is given by F = −H ×M2/Mp, where H is the unified energy function. Between a photon and a slit wall, Hnon-self ̸= 0 and a finite non-equilibrium force arises. The deflection angle of the photon is θ = (y + z)MDc2 (r 2 − (y 2 + z 2)) FPl , where M = m − qme/e is the effective mass of the slit wall, y is the projected radius of the slit, z is the photon radius, D is a dimensionless coupling constant, and FPl is the Planck force. First, we estimate the value of D required for interference fringes to form under realistic slit parameters, obtaining D ≳ 1024. Second, we describe the mechanism by which the radial dispersion from the two slits overlaps to produce regions of high and low photon density, i.e., bright and dark fringes. Finally, we show that when a detector is placed at the slit, a new non-equilibrium force arises between the photon and the detector, disturbing the differential force from the left and right walls, so that the radial dispersion is disrupted and the interference pattern disappears. This is a deterministic picture that explains interference and measurement without invoking wave-function collapse or the complementarity principle. This paper presents a hypothesis and specifies experimental tests.
Feynman (1956) called the double slit experiment "a phenomenon […] has in it the heart of quantum mechanics. In reality, it contains the only mystery. We cannot make the mystery go away by ‘explaining’ how it works". To study the mystery, the double slit experiments were performed one photon at the time. The photons are described by probability wave function. To interpret, the concept of the collapse of the wave function is utilized. However, the collapse of the wave function leads to the inconsistent/incomplete of the quantum mechanics (Penrose, 2022). In this article, we propose Postulate: the diaphragm, e.g., the slide of the double slit, does not change the nature of the light passing through it. Then we perform multi-experiments to test Postulate, and show that, before and after passing the diaphragm of the double slit, the light is photons. It is photons that produce the wave pattern, e.g., the interference pattern. We referred the phenomena as “PhotonWave Phenomena”. Particle phenomena Wave phenomena Light as wave non Light waves produce wave patterns Light as photons Photons produce ejection of electrons: Photoelectric effect Photons produce wave patterns: PhotoWave phenomena A complete interpretation should consistently explain all of the experiments, which challenges the existing wave theories. The experiments show the coexistence of particle nature and wave pattern in the same experiment, which violate Bohr’s complementarity principle and the wave interpretations. The experiments provide the comprehensive phenomena for developing theoretical model to study the nature of the light, the complementarity principle, the wave-particle duality, and wave theories.
