ANSWER: Black Holes
- Professor C.V. Vishveshwara (77), who did pioneering work on black holes, passed away in Bengaluru.
- In the 1970s, while at the University of Maryland, he was among the first to study “black holes” even before they had been so named.
- His calculations gave a graphic form to the signal that would be emitted by two merging black holes – this was the waveform detected in 2015 by the LIGO collaboration, and contained the so-called “quasi normal modes” - a ringdown stage that sounds like a bell’s ringing sound that is fading out.
- In 2015, at a conference to commemorate the detection of gravitational waves, he jokingly said that he should now probably be known as Quasimodo (after having first discovered the quasi normal modes).
- Prof. Vishveshwara also drew cartoons, many of which have been published in physics conference proceedings.
- Prof. Vishveshwara was the founding director of the Jawaharlal Nehru Planetarium in Bengaluru.
- He has written several books including Einstein’s Enigma, or Black Holes in My Bubble Bath.
