- Abstract summary: We discuss the potential use of analogue hydrodynamic systems towards the exploration of quantum gravitational effects.
These include possible insights into the information-loss paradox, black hole physics with Planck-scale quantum corrections, emergent gravity scenarios and the regularization of curvature singularities.
We aim at bridging the gap between the non-overlapping communities of experimentalists working with classical and quantum fluids and quantum-gravity theorists.

- Abstract: The recent technological advances in controlling and manipulating fluids have
enabled the experimental realization of acoustic analogues of gravitational
black holes. A flowing fluid provides an effective curved spacetime on which
sound waves can propagate, allowing the simulation of gravitational geometries
and related phenomena. The last decade has witnessed a variety of hydrodynamic
experiments testing disparate aspects of black hole physics culminating in the
recent experimental evidence of Hawking radiation and Penrose superradiance. In
this Perspective, we discuss the potential use of analogue hydrodynamic systems
beyond classical general relativity towards the exploration of quantum
gravitational effects. These include possible insights into the
information-loss paradox, black hole physics with Planck-scale quantum
corrections, emergent gravity scenarios and the regularization of curvature
singularities. We aim at bridging the gap between the non-overlapping
communities of experimentalists working with classical and quantum fluids and
quantum-gravity theorists, illustrating the opportunities made possible by the
latest experimental and theoretical developments in these important areas of
research
