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

: This is one of the most cited papers on this topic. Tegmark argues that our 3+1 dimensional spacetime (3 space, 1 time) is "privileged." He demonstrates that: Minkowski's mathematical formalism established the idea of a
: 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
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
