Negative Dimension: A Hypothetical Extension of the Dimensional Structure ofSpace-Time

Modern physics describes the observable universe through three spatial dimensionsand one temporal dimension, collectively represented by the four-dimensional space-time framework of relativity. However, the fundamental nature of dimensionality, thestructure of space-time, and the possibility of additional dimensions remain importantsubjects of theoretical investigation. This paper proposes a conceptual framework forexploring a hypothetical entity termed the negative dimension, defined as a potentialadditional degree of freedom that lies beyond the conventional description of spatialand temporal dimensions.
