<p>In this comprehensive study, an original n-dimensional cosmology hypothesis is presented that explains the dimensional structure and dynamics of the universe. The model is based on the fundamental equation relating the total potential energy of the universe (X) to the dimensional parameter (n).</p> <p>Core claims: (1) While the parameter n can mathematically take values in ℝ⁺ (all positive real numbers), in our D = 3 dimensional universe it essentially evolves within the interval [0, 3]; (2) At the boundary values n = 0 and n = 3, the limiting value equals 1, representing singularity as a manifestation of physical uncertainty&mdash;these values constitute physically inaccessible limits as a consequence of geometric necessity; (3) Planck constants (length &asymp; 1.616 &times; 10⁻&sup3;⁵ m, time &asymp; 5.391 &times; 10⁻⁴⁴ s, mass) define the fundamental scales of the universe and indicate the impossibility of infinity; (4) Black holes function as an accelerated version of the universe with matter-energy-string-quantum crystal transformation cycles; (5) Energy conservation and system closure are fundamental principles valid at every scale; (6) The cyclic structure of the universe: Big Bang (quantum bounce, n &rarr; 0) &rarr; Expansion phase (n: 0 &rarr; 3) &rarr; n = 3 barrier acceleration &rarr; Contraction return (n: 3 &rarr; 0) &rarr; Renewed bounce and repetition.</p> <p>The matter in black holes undergoes this cycle in accelerated form: 3D matter &rarr; 2D energy &rarr; 1D string &rarr; 0D-like quantum crystals &rarr; ultimately Planck-scale state. The model provides a new perspective on the dynamic dimensional structure of the universe from cosmic macroscopic scales to black hole microscopic scales, and resolves the classical singularity problem through quantum bounce mechanisms.</p>
