Vadodara: The work carried out by astrophysics and cosmologists Gujarat Dr.
Pankaj Joshi received global recognition.
‘Scientific American’, one of the top journals in the world, has published a cover story about ‘naked singularities’ where Joshi’s paper is the first reference.
Previously, in 2009 that the 150-year-old US magazine had invited Joshi to write full articles on the breaking research.
The article ‘naked singularity’ was published as an international cover story, translated in more than 20 international languages later.
It was for the first time in the seven Independent Indian decades that an Indian scientific study was published as a cover story in the top journal.
Joshi’s work was ahead of Roger Penrose, who ventured Nobel 2021 prize in physics, because of his discovery in 1965.
The theory of Penrose was that the magnificent stars in the universe ended at the end of their lives.
The result was derived using the theory of Einstein’s general relativity.
Singularity is a unique fireball, where density, temperature and all physical amounts arbitrarily and very high.
This is a unique entity in Cosmos, which looks there is no other place, but quantum gravity laws that are unknown will operate there.
“Penrose is always assumed that such singularities must be hidden in the interior of black holes alone.
That is, they have never been seen by many observers like us.
This assumption is called the hypothesis ‘cosmic sensor’.
However, this assumption has never been scientifically proven in the past Some decades, “said Joshi, while taking about his paradigm changing research in black physics.
Working by Joshi, teams and students have shown that singularity or fireball can occur outside the black hole.
“This is also called naked or visible singularity,” Joshi said.
Joshi has written his first paper about this issue in 1986 and then published a series of paper in the ‘fire ball, naked singularity, and blackholes’.
This ended in 1993 the monograph – ‘global aspects in gravity and cosmology’ – published by the University of Oxford Press, included in the famous I-World World I series, the international series of monographs in physics edited by famous Nobel winner scientists .
He proceeded to the author more research papers in famous international journals and top which resulted in the research monographs of both – ‘Gravity Collapse and SpaceTime Singularities’ – published by Cambridge University Press, world-famous series where Stephan Hawking also wrote his monographs.
Joshi’s article is also included in the ‘extreme physics’, a special problem of Sciam where 16 of the top research stories from this decade are written by people like Hawking too.
Publications have produced so much excitement that American lawyers write novels – ‘naked singularity’ who also turn into films now.
