Black hole
A black hole is a region of spacetime from which nothing, not even light, can escape. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that...

Research

Vishveshwara was one of the first to analyze the structure of black holes employing spacetime symmetries thereby demonstrating the existence of the ergosphere. He proved the stability of the non-rotating Schwarzschild black hole, a crucial factor that ensures its continued existence after formation. Further, he discovered the quasinormal modes of black holes. These modes of black hole vibrations are one of the main targets of observation using the gravitational wave detectors. In later years, he investigated black holes in cosmological backgrounds, an important aspect of black hole physics that had hardly been explored. Vishveshwara has also made significant contributions to other areas of general relativity such as the exact solutions of Einstein's field equations, gravitational collapse, compact stellar objects, inertial forces, and spacetime perturbations.

Books and other publications

In addition to authoring a number of technical papers, Vishveshwara has co-edited ten volumes on relativity, astrophysics and cosmology that have been brought out by leading publishers such as Cambridge University Press and Kluwer Academic Publishers. He has contributed articles to these volumes and illustrated two of the volumes with his cartoons, which have been highly appreciated. Further, he has written a number of popular articles on various topics in science.

His book "Einstein's Enigma or Black Holes in My Bubble Bath" is widely acclaimed with highly complimentary comments from Roger Penrose

Planetarium and Promotion of Science

As founder-director of the Planetarium in Bangalore, he has written the scripts of several planetarium programmes and directed them. These have proved to be exceedingly popular because of the simple and attractive manner in which difficult concepts have been presented. Vishveshwara has also produced two short science films.

To promote research as a part of education he started "Research Education Advancement Program".As a part of it, undergraduate students are taught in fundamentals of Physics or Biology by practicing scientists in the field and selected students are involved in research projects at institutes like Indian Institute of Science
