Abstract

Technological advances in controlling and manipulating fluidshave enabled the experimental realization of acoustic analoguesof gravitational black holes. A flowing fluid provides an effectivecurved spacetime on which sound waves can propagate, allowingthe simulation of gravitational geometries and related phenomena.The past decade has witnessed various hydrodynamic experimentstesting disparate aspects of black-hole physics culminating withexperimental evidence of Hawking radiation and Penrose superradiance.In this Perspective article, we discuss the potential use of analoguehydrodynamic systems beyond classical general relativity towards theexploration of quantum gravitational effects. These include possibleinsights into the information-loss paradox, black-hole physics withPlanck-scale quantum corrections, emergent gravity scenarios andthe regularization of curvature singularities. We aim at bridging thegap between the non-overlapping communities of experimentalistsworking with classical and quantum fluids and quantum-gravitytheorists, by illustrating the opportunities made possible by the latestexperimental and theoretical developments in these areas.
