The physicist who dared to challenge the Big Bang's beginning

In short: Most scientists accept the Big Bang as the definitive origin of our universe. But Jayant Narlikar, a visionary Indian astrophysicist, spent his career championing a different reality. He sought a universe without a beginning, rooted in the idea that gravity isn't a force, but a cosmic dance of mass.

Narlikar’s work was defined by a rigorous adherence to first principles, specifically Mach’s principle, which suggests that the inertia of a particle is determined by the distribution of all other matter in the universe. Alongside British astronomer Fred Hoyle, he developed the Hoyle–Narlikar theory of gravitation. This conformal theory attempted to frame gravity as 'action at a distance' rather than a force transmitted by a field, a move that placed his work on the fringes of mainstream physics.

Because Narlikar found the Big Bang model mathematically unsatisfactory due to its singularities—the 'division by zero' he famously loathed—he co-developed the Quasi-Steady State Cosmology. This model proposed a universe without a definitive start point. While this specific model became incompatible with the discovery of the universe's accelerating expansion in 1997, Narlikar continued to refine alternative cosmological visions into the early 2000s.

Beyond theoretical physics, Narlikar was a monumental institutional builder. The Inter-University Centre for Astronomy and Astrophysics (IUCAA) was established in Pune by him during 1988. He envisioned it as a 'scientific democracy,' allowing universities across India to share expensive telescope resources. He structured the center on an 'eight-fold way' inspired by Buddhist schemas, blending high-level research with a deep commitment to public science education and the rejection of pseudoscience like astrology.

His legacy is one of intellectual integrity. Whether he was writing science fiction, mentoring students to pursue 'off-beat' ideas, or designing textbooks for the nation, Narlikar insisted that the universe is not obliged to follow human prejudices. He believed our only true duty is to understand it honestly, a principle he maintained until his death in May 2025.
