“Black holes are the ultimate prisons; what happens inside their event horizons stays inside the horizon.  But their physics is as rich as that of the entire Universe. The various chapters of the book edited by Kenath Arun offer a fascinating journey through the facets of black hole physics, which are at the frontiers of modern physics. From quantum black holes to the biggest classical black holes, the book’s perspective encompasses the entire Universe.” – Avi Loeb, Professor of Science, Director of the Institute for Theory and Computation, Harvard University

The idea of a black hole goes back to Laplace or maybe even earlier to Englishman John Michell, referring to these bodies as ‘dark stars’, way back in 1783. Laplace argued that the largest objects in the universe must become invisible and would hence be dark. When Einstein proposed his general theory of relativity in the early 1900s, Schwarzschild solved the equation (1916) for a spherical star and the solution implied that below a radius (referred to as the Schwarzschild radius), all light and other radiation are trapped inside the star, and it becomes what is called a black hole. With better detection mechanisms, such as the images from the Event Horizon Telescope, the universe of black holes is opening up for astronomical observations and discoveries over all wavelengths. This book covers a wide range of topics related to black holes and their dynamics.
