ANSWER: Professor Vishweshwara
Explanation:
77-year-old Bangaluru-based Professor Vishweshwara who is not only among the first in India to study black holes, but who has also made a very important calculation that was used in this discovery of gravity waves using the advanced LIGO (Laser Interferometer Gravitational Wave Observatory) detectors. Through the initial signal, the “chirp”, the steadily increasing frequency and amplitude of the gravitational waves indicates the inspiralling of two black holes and the ring down ( or the quasi-normal mode, QNM) indicates the newly created black hole after the merger. He is credited as the Black Hole Man of India.
