Famous "information paradoxes" in black hole theory can be resolved if quantum information on horizons is delocalized or "spooky", like states of entangled particles. Similar spooky quantum degrees of freedom on the inflationary horizon are estimated to produce curvature perturbations with a dimensionless power spectral density larger than those from standard field fluctuations, but consistent with current measurements. Spooky perturbations with primordial directional antisymmetry have unique signatures that can be (but have not yet been) rigorously tested in CMB anisotropy and large scale galaxy surveys.
