 Unique negative dimension

The term "unique negative dimension" is not widely recognized in mainstream mathematics or science, and it does not refer to a standard concept. However, it might be a term used in specific contexts, such as theoretical physics, cosmology, or certain branches of advanced mathematics. In some theoretical frameworks, particularly in string theory and other advanced theories in physics, dimensions can behave in unconventional ways. Dimensions are typically considered as quantities that describe the spatial or temporal extent of an object or universe.
