Phys. Rev. Lett. 95, 160403 (2005) [4 pages]Testing Gravity-Driven Collapse of the Wave Function via Cosmogenic NeutrinosReceived 1 March 2005; published 12 October 2005 It is pointed out that the Diósi-Penrose ansatz for gravity-induced quantum state reduction can be tested by observing oscillations in the flavor ratios of neutrinos originating at cosmological distances. Since such a test would be almost free of environmental decoherence, testing the ansatz by means of a next generation neutrino detector such as IceCube would be much cleaner than by experiments proposed so far involving superpositions of macroscopic systems. The proposed microscopic test would also examine the universality of the superposition principle at unprecedented cosmological scales. © 2005 The American Physical Society URL:
