Jayant Narlikar

Jayant Narlikar

Astrophysicist Who Challenged the Big Bang Theory

About Jayant Narlikar

Dr. Jayant Vishnu Narlikar (July 1938–May 2025) was a towering figure in Indian science, best known for his pioneering contributions to cosmology and for advocating an alternative to the widely accepted Big Bang theory 

  • Besides his groundbreaking scientific work, he was a passionate science communicator, institution builder, and rationalist who inspired generations of researchers and the general public alike. 

Early Life and Academic Journey 

  • Born on 19th July 1938, in Maharashtra, Narlikar grew up in an intellectually rich environment. His father was a distinguished mathematician, while his mother was a respected Sanskrit scholar.  
  • He completed his Bachelor of Science at Banaras Hindu University (BHU) in 1957 and went on to the University of Cambridge for advanced studies, earning a PhD in 1963 under the mentorship of eminent physicist Sir Fred Hoyle. 

Scientific Contributions and Theories 

  • Narlikar first gained international prominence through his collaboration with Fred Hoyle, co-developing the Quasi steady state theory of the universe. This model challenged the Big Bang theory by positing that the universe is eternal, with matter continuously created to maintain a constant density despite expansion.  
    • This theory incorporated Mach’s principle, suggesting inertia depends on the mass distribution in the universe. 
  • Later, Narlikar refined this into the Quasi-steady State Cosmology (QSSC), proposing periodic mini-creation events rather than a Big Bang 
  • Though observational evidence supports the Big Bang theory more robustly, Narlikar’s steady state models provided important theoretical frameworks and stimulated valuable scientific discourse. 

Institution Building and Scientific Legacy 

  • Returning to India in 1972, Narlikar joined the Tata Institute of Fundamental Research (TIFR), strengthening the Theoretical Astrophysics Group.  
  • In 1988, he founded the Inter-University Centre for Astronomy and Astrophysics (IUCAA) in Pune, which under his leadership became a globally respected centre for astronomy and astrophysics research and education. 
  • He remained IUCAA’s director until 2003 and continued as an emeritus professor, emphasizing outreach programs for schoolchildren and the public.  
  • He believed in nurturing young talent early, famously saying– 

 “PhD scholars don’t fall from the sky, you must catch them young.” 

Science Communication and Literary Contributions 

  • Apart from his scientific work, Narlikar was a prolific science communicator, authoring over 300 research papers and numerous books in English and Marathi.  
  • Notable among his literary works are the science-fiction story The Comet (Dhoomaketu), adapted into a film, and his autobiography My Tale of Four Cities (Chaar Nagarantale Maze Vishwa), which won the Sahitya Akademi Award.
