Contemporary cosmological models occasionally invoke higher-dimensional interactions, such as brane collisions, to explain the origin of the universe. These descriptions are often presented as extensions of physical explanation. This paper clarifies a prior condition: before such structures can be meaningfully described, they must satisfy admissibility. Using the Paton System, the distinction is drawn between dimensional description and tier-based admissibility. It is shown that many higher-dimensional claims remain within possibility space (Tier 2) and do not yet satisfy the conditions required for admissible continuation (Tier 3). The result is a structural reframing: dimensions describe, tiers permit.
Andrew John Paton (Tue,) studied this question.
