Remembering the Indian scientist who challenged the Big Bang theory

In his 1983 science fiction story, an Indian astrophysicist predicted what colleges would seem like in 2050.

Jayant Narlikar envisioned a scene the place an alien, residing amongst people, would sit in entrance of a display screen and attend on-line lessons. The aliens are but to manifest, however on-line lessons grew to become a actuality for college kids far sooner, in 2020, when the Covid-19 pandemic hit.

Narlikar additionally famously proposed a substitute for the Massive Bang Idea – the favored concept that the universe was created in a single second from a single level. He believed that the universe had all the time existed, increasing constantly into infinity.

Along with his passing on Tuesday, India misplaced one in every of its most celebrated astrophysicists. Narlikar was 86 – a person far forward of his occasions and somebody who formed a era of Indian researchers by way of his lifelong dedication to science schooling.

His funeral was attended by lots of, from faculty kids to famend scientists and even his housekeeping employees, underscoring the profound influence he had on society.

Born on 19 July, 1938, within the city of Kolhapur within the western state of Maharashtra, Narlikar was raised in a house steeped in tutorial custom.

His father, Vishnu Narlikar, was a professor and mathematician, and mom Sumati was a scholar of the Sanskrit language.

Following in his dad and mom footsteps, the studious Narlikar went to Cambridge College for increased research the place topped a extremely prestigious mathematical course. He additionally took a deep curiosity in astrophysics and cosmology.

However his most vital episode at Cambridge was his affiliation together with his PhD information, physicist Sir Fred Hoyle. Collectively, Narlikar and Hoyle laid the groundwork for a revolutionary various to the favored Massive Bang idea.

The 2 physicists contested the Massive Bang Idea, which posits that each one matter and vitality within the universe got here into existence in a single single occasion about 13.8 billion years in the past.

The Hoyle-Narlikar idea boldly proposed the continual creation of latest matter in an infinite universe. Their idea was primarily based on what they known as a quasi-steady state mannequin.

In his autobiography, My Story of 4 Cities, Narlikar used a banking analogy to clarify the speculation.

“To know this idea higher, consider capital invested in a financial institution which provides a hard and fast charge of compound curiosity. That’s, the curiosity accrued is consistently added to the capital which due to this fact grows too, together with the curiosity.”

He defined that the universe expanded just like the capital with compound curiosity. Nonetheless, because the identify ‘regular state’ implies, the universe all the time appears to be like the identical to the observer.

Astronomer Somak Raychaudhury says that although Narlikar’s idea is not as fashionable because the Massive Bang, it’s nonetheless helpful.

“He superior mechanisms by which matter may very well be regularly created and destroyed in an infinite universe,” Raychaudhary mentioned.

“Whereas the Massive Bang mannequin gained broader acceptance, many instruments developed for the steady-state mannequin stay helpful as we speak,” he added

Raychaudhary recollects that even after Hoyle started to entertain components of the Massive Bang idea, Narlikar remained dedicated to the steady-state idea.

An indication exterior his workplace fittingly acknowledged: “The Massive Bang is an exploding fable.”

Narlikar stayed within the UK until 1971 as a Fellow at King’s Faculty and a founding member of the Institute of Theoretical Astronomy.

As he shot to international fame within the astrophysics circles, the science neighborhood in India took observe of his achievements.

In 1972, he returned to India and instantly took cost of the Theoretical Astrophysics Group on the coveted Tata Institute of Basic Analysis, which he led it until 1989.

However his largest contribution to India was the creation of an establishment devoted to cutting-edge analysis and the democratisation of science.

This dream materialised in 1988, when Narlikar, together with different distinguished scientists, based the Inter-College Centre for Astronomy and Astrophysics (IUCAA) in Pune metropolis in western India.

From a modest 100sq ft room, IUCAA has gone on to grow to be an internationally revered establishment for astronomy and astrophysics.

Narlikar served as its founder-director until 2003, and continued to be an emeritus professor after that.

He insisted that IUCAA ought to embrace packages aimed at college kids and most of the people. Month-to-month lectures, science camps, and workshops grew to become common occasions.

Recalling Narlikar’s imaginative and prescient for the establishment, science educator Arvind Gupta says, “He mentioned PhD students do not fall from the sky, you have to catch them younger. He provided me a spot to remain, informed me to strive operating the kids’s science centre for six months, and I ended up staying 11 years. He gave me wings to fly.”

Regardless of being a prolific scholar who printed over 300 analysis papers, Narlikar by no means confined himself to being only a scientist. He additionally authored many science fiction books which were translated into a number of languages.

These tales have been usually grounded in scientific rules.

In a narrative known as Virus, printed in 2015, he envisioned a pandemic taking on the world; his 1986 e-book Waman Parat Na Ala (The Return of Vaman), tackled the moral dilemmas of synthetic intelligence.

Sanjeev Dhurandhar, who was a part of the Indian group that contributed to the bodily detection of gravitational waves in 2015, recalled how Narlikar impressed him to try the unthinkable.

“He gave me a posh downside early in my analysis. After I struggled for per week, he solved it on the board in quarter-hour – to not present superiority, however to information and encourage. His openness to gravitational waves was what gave me the braveness to pursue it.”

A widely known rationalist, Narlikar additionally took it upon himself to problem pseudoscience. In 2008, he co-authored a paper that challenged astrology utilizing a statistical technique.

Raychaudhary mentioned that his motivation to problem pseudoscience got here from the assumption system of questioning all the things that didn’t have a scientific foundation.

However when it got here to science, Narlikar believed in exploring the slimmest of prospects.

In his final days, Narlikar continued doing what he cherished most – replying to kids’s letters and writing about science on his weblog.
