Book Review of Quantum Time

“Quantum Time” is an academic monograph written by Liu Yingping in 2017, exploring the profound connection between the nature of time and quantum phenomena. Taking the materiality of time and space as a starting point, the book systematically investigates cutting-edge issues such as the concept of time in the quantum world, quantum extension, gravity, and acceleration. It also attempts to unify quantum mechanics and general relativity in higher dimensions. Rich in content, the book spans a wide range of topics— from fundamental theories to complex phenomena—offering readers a novel perspective for understanding the mysteries of time and quantum mechanics. The proposed theory of Outflow Time, along with the author’s unique interpretations of classic quantum phenomena such as the double-slit experiment and quantum entanglement, demonstrates both bold theoretical innovation and dedicated inquiry. Furthermore, the book’s discussion of dark matter and dark energy provides fresh insights into some of the most debated issues in contemporary cosmology.
