BENGALURU: When scientists from the Laser Interferometric Gravitational-wave Observatory ( LIGO ) project announced the finding of gravitational waves on February 11, the global scientific community celebrated them and also Albert Einstein who had spoken of the waves a Century ago.LIGO’s finding hasn’t just proved Einstein right, according to Research Collective Gubbi Labs , whose statement has claimed that the finding of gravitational waves has proved an important concept predicted by Bengaluru-based scientist CV Vishveshwara , a black holes expert “...The cosmic event that led to the discovery of the gravitational waves was the in-spiralling and eventual merger of two black holes deep in space. It was Vishveshwara’s work, carried out between 1968 and 1970, that provided fundamental insights into the nature of black holes,” Gubbi Labs has said.According to the statement, Vishveshwara used the equations of Einstein’s theory of general relativity to carry out meticulous calculations and analyse the structure of black holes. He went on to prove the stability of black holes that assured their continued existence in nature, once they were formed.“...In 1970, continuing his study of black holes, Vishveshwara discovered what are called the ‘quasi-normal modes’ – the gravitational wave packets scattered by the black holes or the ringdown of black holes. He further predicted that these scattered gravitational waves carry the signature of the black holes by which they were scattered,” the statement said.Adding that other researchers, building on his work, calculated the ‘quasi-normal modes’ for different black hole configurations, including the one formed by the merger of two black holes, the statement said: “While discovering the gravitational waves, the team of scientists at LIGO has also detected the ‘quasi-normal modes’.”“Stunningly, the modes they observed were the same as those predicted by Professor CV Vishveshwara more than 45 years ago. It is not just Einstein who has been proved right; our own scientist, who lives with us here in Bengaluru, has also been proved right!,” the statement said.While Vishveshwara wasn’t immediately available, TOI will interview him on Friday.
