Reconsidering the Fourth Dimension: Time as Dimension T and Higher-Dimensional Explanations for Quantum Nonlocality

Time is commonly incorporated as the fourth dimension of relativistic spacetime. Yet time differs operationally from spatial dimensions, exhibiting irreversibility and non-navigability that do not have a spatial analogue. This paper proposes a reinterpretation in which time is treated as a universal ordering parameter, denoted Dimension T, while the fourth dimension is taken to be spatial. Observed three-dimensional configurations are modelled as a T-parametrized projection of a higher-dimensional spatial manifold. Within this framework, apparent quantum nonlocal correlations are interpreted as locality in the higher-dimensional spatial description combined with information loss under projection, without requiring superluminal signalling in the observed description.
