R.I.P. Jayant Narlikar (1938-2025)
Professor Jayant Vishnu Narlikar (1938-2025)I heard this morning of the death at the age of 86 of renowned Indian cosmologist Jayant Vishnu Narlikar. I understand he died peacefully in his sleep in Pune after a brief illness.
Scientifically, Jayant Narlikar is probably best known for his work with Fred Hoyle on a conformal gravity theory and as an advocate of the Steady State theory of cosmology. In India however his fame extended far beyond the world of research, as an educator and science popularist, as well as Founder-Director of the Inter-University Centre for Astronomy and Astrophysics (IUCAA) in Pune. Those who met him – as I was lucky enough to do – will also remember him as a kind and gracious man, and a self-effacing inspirer of young scientists. During my visit I gave a talk there, which Narlikar attended, and we had a very nice conversation afterwards from which I learnt a huge amount.
The Directorship at IUCAA came with a house which had a very nice lawn, on which I remember playing croquet with Donald Lynden-Bell and others, but that’s another story. Another random thing I remember is that I remember is that Narlikar’s username on the IUCAA email system was “jvn” and he was often referred to informally by that name.
Although he never really abandoned the Steady State cosmology, despite the weight of evidence in favour if the Big Bang, it is to Narlikar’s great credit that he didn’t try to impose his own scientific ideas on those working at IUCAA. In fact he assembled an excellent group of cosmologists and astrophysicists and encourage them to do whatever they liked.
I first visited IUCAA in 1994 to work with Varun Sahni. In those days Westerners mainly went to Pune to visit an ashram (usually the one run by the guru Rajneesh). I remember when I arrived on the train from Mumbai and tried to get a taxi to the IUCAA campus, the driver asked me “which ashram?” I had long hair and a beard at that time, so I looked a potential hippy. I said, “No ashram. Professor Narlikar”. He knew exactly where to take me; “Narlikar” was a household name in India, where the newspapers are awash with tributes today (e.g. here) and where his loss will be keenly felt.
Rest in peace Jayant Narlikar (1938-2025)
