This of course is the problem with this topic: Too much psuedo-science. 
Dinesh Abrol writes
"FOR the first time in the Indian Science Congress in its 102 years history, the organisers held a symposium on “Ancient Sciences through Sanskrit”. Seven papers presented over the five-hour session were invited by the Department of Sanskrit, Mumbai University, and Kavi Kulaguru Kalidas University, and reviewed by the Mumbai University’s Department of Sanskrit. Evidence of ancient aviation in the Rigveda was claimed in a paper co-authored by Captain Anand Bodas, retired head of a pilot training centre, and Ameya Jadhav, a teacher. The paper talked about the existence of interplanetary aircraft in India around 9000 years ago. It had references to “cosmic connection” and a phenomenon explained in terms of “fusion of science and spirituality due to inter-penetration law”. Proof for the claim for the author was some Sanskrit text called Vymanika Shastra written 7000 years ago. There were also other outlandish claims made at the Symposium like the existence of a cow carrying a bacteria in its body which enables it to turn whatever it consumes into pure 24 carat gold, helmet on Mars from Mahabharata days, autopsies were being conducted in ancient days by leaving the dead bodies to float in water for three days and Pythagoras’ Theorem invented in India, not Greece.
Speakers at the symposium on “Ancient Sciences through Sanskrit” included mostly students of Sanskrit and only some professionals. The presenters ended up reducing the contribution to scientific and technological knowledge from ancient India to mythology based talks. Speakers talked of the discoveries made from India during the early Vedic period. The presenters used liberally the occasion to make a large number of outrageous claims. Claims made were pseudo-scientific without producing scientific evidence. Speakers had only the references from Sanskrit texts to present in the name of evidence. Unbelievable dates of the discoveries attributed to the early Vedic period across different branches of knowledge made the claims of the speakers even more suspect. Presenters of the papers at the symposium had little to do either with the pursuit of science or the history of science, and their interest was to bring to the fore the claims that justified RSS ideology. They wanted to use the prestigious scientific platform to give the aura of science to their claims.
Not only the claims made at the symposium were clearly inconsistent with the tradition of scientific method..."
