Abstract:This paper starts from the mapping of the time dimension in general relativity to the frequency and frequency gradient distribution of a 3D real-space lattice point network, exploring the viewpoint that all dimensions beyond the three spatial coordinates in higher-dimensional theories are actually dynamical degrees of freedom of spatial lattice points.

Introduction:The world perceived by humans is a changing three-dimensional space. To cover more phenomena, the physics community has developed models such as the 4-dimensional spacetime of general relativity and the multi-dimensional spaces of string theory. How to understand these higher-dimensional theories more intuitively starting from the 3D space that people directly perceive has become a key issue in learning or teaching.

You can write a PREreview of Demystifying Extra Dimensions via 3D Lattice Dynamics. A PREreview is a review of a preprint and can vary from a few sentences to a lengthy report, similar to a journal-organized peer-review report.
