Overview
What This Research Does
Cosmology, astrophysics, geology, paleontology, and embryology — examined in parallel with Purāṇic descriptions to reveal systematic correspondence.
Purāṇic time-cycle calculations match the age of the solar system and universe to within 0.1% of current scientific measurements.
Grounded in original Purāṇic texts, with careful translation and cross-referencing across the Bhāgavata, Matsya, and Padma Purāṇas.
Endorsed by researchers at Columbia University, the University of Melbourne, Rush University, and the Smithsonian Museum of American History.
The Research
A Rigorous Case for the Scientific Depth of the Purāṇas
This research began with a precise and verifiable observation: the chronological frameworks in the Purāṇas — the Yuga cycles, the Manvantara calculations, the lifespan of Brahmā — yield numerical values that correspond with striking accuracy to the findings of modern astrophysics, geology, and biology.
Rather than reading the Purāṇas through the lens of metaphor or mythology, this work takes their descriptive claims seriously as empirical statements and examines them against the scientific record. The result is a cross-disciplinary investigation spanning cosmology, astrophysics, geology, paleontology, and embryology.
The research also engages with deeper questions of epistemology — how a pre-telescopic civilisation could encode such precise knowledge, and what the Purāṇic framework of higher-dimensional reality may offer as a model for phenomena that elude current scientific explanation.
The findings have been published in the book The Big Bang and The Sages and presented at universities and research institutes across India and the United States.
Key Findings
What the Research Reveals
Age of the Universe
Purāṇic time-cycle calculations yield values for the age of the solar system and universe accurate to within 0.1% of modern astrophysical measurements — a correspondence that demands scholarly attention.
Geological Deep Time
Vedic texts describe planetary and biological epochs that align with the paleontological record, including accounts of ancient life-forms that parallel the fossil sequence documented by modern science.
Embryological Knowledge
Descriptions of fetal development in the Purāṇas correspond with precision to stages of embryological development that Western science only systematically described in modern times.
The Yuga System
The Yuga cycle encodes a mathematically precise cyclical model of time whose internal logic and geological correlates are examined in depth.
Manvantara Calculations
The Manvantara system involves astronomical calculations of extraordinary precision, compared against current cosmological models with remarkable results.
Higher-Dimensional Reality
Certain Purāṇic descriptions — including Bhū-maṇḍala — are proposed to reflect a higher-dimensional reality whose four-dimensional projection corresponds to what we observe scientifically.
Endorsements
What Scholars Are Saying
“The authors bury skeptics under an avalanche of well-researched facts. A real tour-de-force of scientific expertise.”
Prof. K. Pahan — Rush University
“This book illustrates how the Puranas provide both a microscopic and telescopic view of the physical world from which modern science can learn and benefit.”
Prof. R. Buyya — University of Melbourne
“You have synthesized challenging material from at least four different fields into a thought-provoking and compelling vindication of the Puranic cosmo-chronological order.”
A. Saha — Smithsonian Museum of American History
“Chhabra and O’Rourke have dexterously sewn together state-of-the-art discoveries in five fields: cosmology, astrophysics, geology, paleontology, and embryology.”
Prof. S. Ghosh — Columbia University
Reader Reviews
What Readers Say
“Absolutely in love with this book. The comparison between the Puranas and astronomy is very interesting and thought-provoking. I found most of this book exhilarating and have gasp-worthy moments.”
“Fantastic book about the correlation of Puranas and major geological events. Kudos — and proud of our ancestors.”
“The writing is superb and not only provides amazing insights but also inspires further research into its profound concepts.”
“Excellent — a good comparison of Puranic concepts with what has been discovered by empirical science through experiments and the latest technological developments.”
“A thought-provoking read that encourages readers to contemplate the mysteries of our world through a multidisciplinary lens. These scriptures offer profound insights into cosmology, time, and space.”
“This book completely reshaped my understanding of Sanatan Dharma. Rather than dismissing ancient texts as mythology, the authors invite us to recognise knowledge far ahead of its time.”

About the Researchers
Speaking
Bringing Ancient Wisdom and Modern Science Into Conversation
These are not lectures about religion. They are rigorous, evidence-based presentations on one of the most remarkable and underexplored questions in intellectual history: did the ancient Vedic sages possess scientific knowledge that modern civilisation is only now rediscovering?
Each presentation is tailored to the audience — with visual aids, Sanskrit references, accessible explanations, and space for dialogue. Suitable for universities, research institutes, interfaith forums, spiritual communities, and cultural organisations.
-
Talk 01 — SignatureThe Big Bang and The SagesThe core thesis presented across five scientific disciplines. Suitable for general audiences and academic settings alike.
-
Talk 02Ancient Time, Modern Science: The Yuga System ExaminedA focused exploration of the Yuga and Manvantara cycles — their mathematical structure and geological correlates.
-
Talk 03Science Meets Scripture: A New ParadigmThe limits of materialist science and what the Purāṇic knowledge system offers as a rigorous complement.
-
Talk 04Vedic Cosmology for the 21st CenturyFor Hindu and Vaishnava community audiences — the intellectual depth of the tradition and its contemporary relevance.
-
Talk 05Custom & Collaborative PresentationsTailored to specific themes, disciplines, or audience needs — available upon consultation with organisers.
