Noether’s theorem is widely regarded as foundational in classical physics, particularly in deriving conserved quantities from continuous symmetries, such as the conservation of energy from time-translation invariance. However, this symmetry-first narrative implicitly assumes the very thing it seeks to explain: a cohesive, universally valid time parameter capable of supporting adjacent events, differential evolution, and the composability of dynamical processes. This assumption — the cohesion of time — proves untenable in regimes where temporal cohesion is not actively enforced as a physical mechanism. In such cases, including flattened, severed, or incohesive temporal sectors, the standard Noether condition ∂L/∂t = 0 fails to function as a conservation law. Instead, the associated statement dE/dt = 0 collapses into a time-void identity, reflecting the absence of a consistent temporal support on which dynamical evolution could be defined. We formalize this failure as the Noether-free Time-Void Theorem: without enforced temporal cohesion, dynamical laws, entropy production, and probabilistic measures over trajectories cannot be defined. In such a regime, symmetry collapses into equilibrium-to-zero, no longer generating transport but enforcing a null state where nothing evolves. This collapse of dynamical behavior reflects the absence of an underlying cohesive temporal structure. This foundational flaw in the symmetry-first framework is further amplified in quantum field theory
