The article "Analogue Gravity" by Carlos Barceló, Stefano Liberati, and Matt Visser provides an overview of the historical development, aims, results, and future prospects of analogue models of gravity. These models use physical systems, such as acoustic or optical phenomena, to mimic aspects of curved spacetime and quantum field theory in curved spacetime. The authors start with a simple example of acoustic gravity, where supersonic fluid flow can create an "acoustic black hole" and generate Hawking radiation, providing a laboratory model for studying curved-space quantum field theory. The article discusses the mathematical and physical connections between these models and general relativity, highlighting the existence of an effective metric that captures key features of spacetime curvature. It also explores the broader implications of analogue models, including their potential for advancing our understanding of quantum gravity and the emergence of gravity from more fundamental theories. The review concludes by outlining future directions, including the role of back reaction, the equivalence principle, and the development of quantum gravity models based on analogue principles.The article "Analogue Gravity" by Carlos Barceló, Stefano Liberati, and Matt Visser provides an overview of the historical development, aims, results, and future prospects of analogue models of gravity.
