Time Has Two Dimensions-Exploring Coordinate Connotation of Five-Dimensional Space

Abstract

Following Theodor Kaluza, Itzhak Bars and David Bohm�s idea, recognizing the rationality of B. Feng�s new physics theory, based on five-dimensional space, the corresponding coordinate connotation has determined through reasoning, represent as form as (x, y, z, ict, iat 2 ). Where, a is the curvature acceleration of light, and equals to 10 31 m/s 2 . It is believed to be the limit acceleration in universe, nothing could beyond.
