: The historical foundation of spacetime. Minkowski's mathematical formalism established the idea of a four-dimensional world where space and time are inextricably linked into a single continuum. Theoretical Frameworks with Extra Dimensions Spacetime Dimension

Several foundational and modern papers explore the dimensionality of spacetime, ranging from explaining why our universe has 3 spatial and 1 temporal dimension to theoretical frameworks involving multiple time dimensions or "scale-dependent" dimensionality.
