Famous Indian Relativists
Honouring the pioneering minds who shaped the development of General Relativity, Cosmology, Gravitation, and Astrophysics in India.
From foundational mathematics to black holes, cosmology, and gravitational collapse, these scholars helped build India’s distinguished tradition in relativity research.
