Xiao En Wang’s research focuses on interdisciplinary fundamental theoretical studies bridging quantum mechanics, atomic physics, and cosmology. His work explores the nature of photon wave–particle duality, advanced atomic models, and the fundamental structure of matter. He is also deeply interested in the formation and evolution of the Earth, the Solar System, and celestial bodies, along with broader cosmological questions such as the origin, expansion, and physical laws governing the universe. Additionally, his research extends into related domains including cell biology, genetics, and molecular biology, aiming to develop unified perspectives across multiple scientific disciplines.

Xiao En Wang was born on March 30, 1950, in a rural area of Qingzhou City, Shandong Province. He retired in 2010 as a professor at Weifang Engineering Vocational College. His primary interest is interdisciplinary research in fundamental theoretical sciences. He has developed original perspectives in areas such as quantum mechanics, atomic physics, the formation of the solar system, the origin of the Earth and the Moon, the evolution of celestial bodies, cosmology, cell biology, genetics, and molecular biology. Reference: Photons, Atoms, Earth, Solar System, and Universe This presentation explores a unified theoretical perspective spanning photon structure, atomic models, planetary formation, and cosmology. It proposes an interpretation of photon wave–particle duality in which a photon is described as a complete wave train characterized by a head, tail, and finite length. In this framework, a visible-light photon consists of numerous wave cycles, with defined relationships between head, tail, and average wavelengths. Photons are treated as indivisible entities that can only be emitted and absorbed as a whole. The study further introduces a modified model of the hydrogen atom, addressing limitations in the traditional Bohr model by incorporating additional physical considerations. It also critically examines aspects of wave mechanics and energy formulations in atomic theory. Beyond atomic structure, the presentation outlines a model for the formation of the Earth and the Solar System, suggesting that planets originated from early solar ejections of gas–liquid matter, with satellites forming from subsequent fragmentation processes. At the cosmological level, the universe is described as a finite but unbounded system undergoing continuous expansion. The model emphasizes the unidirectional nature of time, supported by cosmic redshift and entropy increase. It proposes that the universe originated from a dense neutron state approximately 13.44 billion years ago and has since expanded with uniform acceleration. Relationships among fundamental constants—such as the speed of light, gravitational constant, and Hubble constant—are discussed in relation to cosmic evolution. This interdisciplinary work integrates concepts from quantum mechanics, astrophysics, and cosmology, supported by nearly 20 publications by the author over the past decade.
