Standard cosmological models traditionally view core-collapse supernovae as terminal thermodynamic events—catastrophic endpoints resulting in localized entropy maximization and the seemingly chaotic dispersion of stellar nucleosynthesis products into the interstellar medium. This paper introduces and formalizes the theoretical framework of Infinite Fractal Descent (IFD), proposing that such stellar deaths represent non-linear phase transitions of energy, matter, and information. By analyzing the deceleration kinematics and the geometric fractal dimension () of remnant shockwaves, with a primary focus on the Cassiopeia A (Cas A) supernova remnant, we demonstrate that macroscopic kinetic energy does not merely dissipate entropically into a vacuum. Instead, it descends through a recursively structured, scale-invariant geometric gradient. This turbulent "shredding" process mathematically and physically maximizes the boundary surface area for elemental mixing, actively converting macro-scale kinetic stagnation into the fundamental building blocks of micro-scale complexity, ultimately bridging high-energy astrophysics with the chemical precursors of biological evolution.
