Koku Universe: Distance as Layer Density and the Unification of Temporal Speed

We propose a fundamental principle of the Koku Universe model: 'Distant objects appear slow; near objects appear fast.' (遠くは遅く、近くは速い。) This single observation unifies relativistic time dilation, angular momentum conservation, gravitational effects near black holes, and the parallax phenomenon under one geometric framework. In the Koku Universe (U = T x G), spatial distance is defined as the number of stacked Koku-planes between the observer and the observed. Greater layer density corresponds to slower apparent temporal progression. Unified under: v_t proportional to 1/N. Part of TheYKHC Research Series.
