Analogue models of gravity is a direction of research in physics, where various phenomena of general relativity (e.g., black holes or cosmological geometries) are modeled by other physical systems, such as acoustics in a moving fluid, superfluid helium, or Bose-Einstein condensate; gravity waves in water; and propagation of electromagnetic waves in a dielectric medium. These analogues (or analogies) serve to provide new ways of looking at problems, permit ideas from other realms of science to be applied, as well as potentially creating opportunities for practical experiments within the analogue that can hopefully be applied back to the source phenomena.
