Title: Quantum Indeterminacy of Cosmic Systems

It is shown that quantum uncertainty of motion in systems controlled mainly by gravity generally grows with orbital timescale $$H^{-1}$$, and dominates classical motion for trajectories separated by distances less than $$\approx H^{-3/5}$$ in Planck units. For example, the cosmological metric today becomes indeterminate at macroscopic separations, $$H_0^{-3/5}\approx 60$$ meters. Estimates suggest that entangled non-localized quantum states of geometry and matter may significantly affect fluctuations during inflation, and connect the scale of dark energy to that of strong interactions.
