Spacetime Dimension Access

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. Landmark Papers on Spacetime Dimensions

would make physics unpredictable because partial differential equations would lack the "hyperbolicity" property. Spacetime Dimension
