Anil Prabhakar had been working at IIT Madras for eight years when he went to see Nergis Mavalvala at the Massachusetts Institute of Technology (MIT). Prabhakar, an experimental physicist who researches on quantum optics, had been approached in 2010 by Bengaluru-based theoretical physicist Bala Iyer for interest in participation in the inchoate Indian gravitational wave project, at that time called IndIGO. Mavalvala was then part of the team that would go on to discover gravitational waves in 20

An old wine in a new bottle. An experiment more than two centuries old helps physicists measure gravitational fields on the smallest scales possible. A group of researchers from Vienna University performed an experiment that sparked hopes of observing gravity in its quantized form (T. Westphal et al., Nature 591, 225, 2021). Among the four fundamental forces of nature (electromagnetic force, gravitational force, strong nuclear force, and weak nuclear force), gravity is not only the weakest but a
