This letter briefly gives an overview of the theory proposed in quant-ph/9906130 and quant-ph/9909025 on the basis of quantum mechanics. Although quantum mechanics in twentieth century has succeeded to predict the correct results of large numbers of experiments in the process to find new fundamental particles in the nature, it seems to have left some fundamental open problems, both structural and conceptual ones: 1. the structural problems: • the ambiguity of the operator ordering [1, 2], • the nonanalycity at the exact classical-limit of h̄ = 0, • the semantics of the regularization method in quantum field theories; 2. the conceptual problems: • the inconsistency with the completeness, • the wave-reduction mechanism in measurement processes, • the incompatibility with causality [3, 4, 5]. These difficulties come from the problem how and why quantum mechanics relates itself with classical mechanics: the relationship between the quantization that constructs quantum mechanics based on classical mechanics and the classical-limit that induces classical mechanics from quantum mechanics as an approximation with Planck’s constant h taken to be zero; the incompatibility between the ontological feature of classical mechanics and the epistemological feature of quantum mechanics in commonly accepted interpretations. The introduced theory [6], originated by the previous paper [7], aims to solve all of the above listed problems in quantum mechanics. Paper [6] proposes a basic theory on physical reality, named as Structure behind Mechanics. It supposes that a field or a particle X on the four-dimensional spacetime has its internal-time õP(t)(X) relative to a domain P(t) of the four-dimensional spacetime, whose boundary and interior represent the present and the past at ordinary time t, respectively. For h̄ = h̄/2, the classical action h̄SP(t)(X) realizes internal-time õP(t)(X) in the following relation: õP(t)(X) = e P(t). (1) † e-mail: [email protected] or [email protected]
