G Nageshwar Rao, the vice chancellor of Andhra University, took the stage to deliver a talk on day two at the Congress, where he claimed that India was well aware of stem cells, test tube fertilisation and guided missiles thousands of years ago, citing tales from Mahabharata and Ramayana, according to a PTI report.

"We had hundreds of Kauravas from one mother because of stem cell research and test tube baby technology," Rao claimed. "It happened a few thousand years ago. This was science in this country... Mahabharat says 100 eggs were fertilised and put into 100 earthen pots. Are they not test tube babies? Stem cell research in this country was present thousands of years ago."

Another supposed "scientist", Kanan Jegathala Krishnan, took the stage on day 2 of the Science Congress on Friday and delivered a talk on Einstein’s theories.

"Space is heavier than the sun and every other planet and hence compresses all the planets. Equal pressure is applied to them, which is why they are moving," Krishnan said. "The quality of space is self-compressive, which is something that Newton and Einstein could not understand. Einstein did not guide the world in the correct way."

According to Krishnan, the Minister for Science and Technology Dr Harsh Vardhan will be a bigger scientist in the future than Dr A P J Abdul Kalam ever was. And if that wasn’t nearly enough, he went on to say that once his theories about gravity were accepted, what the world has come to know as "gravitational waves" will then be named "Narendra Modi waves (Mr. Narendra Modi is the Prime Minister of India.) ", and gravitational lensing, the "Harsh Vardhan effect".

Mr. Kanan Jegathala Krishnan, who claimed to be a senior research scientist at the World Community Service Centre in Tamil Nadu, said English physicist Isaac Newton had very little understanding of gravitational forces, while theoretical physicist Albert Einstein had misled the world with the theory of relativity.

Another speaker Captain Anand Bodas, a retired pilot, was presenting a paper on ‘Ancient Indian Aviation Technology’, and claimed that the science of building and flying a plane was recorded by Maharshi Bharadwaj in Brihad Vimana Shastra, written between 6000 BC and 7000 BC, several millennia before the Wright Brothers built a plane. "Maharshi Bharadwaj said air planes were used to travel from one city to another, from one country to another and from one planet to another."

Scholars at the Indian Institute of Science in Bangalore have straightforwardly debunked this text. They say it was actually written between 1900 and 1922. So much for Bodas' exaggerated claims.

Mr. Bodas also spoke of jumbo planes which flew in ancient India. "The basic structure was of 60 by 60 feet and in some cases, over 200 feet. They were jumbo planes," he said. He also claimed, again without any scientific evidence, that ancient planes had several engines. "The ancient planes had 40 small engines. Today's aviation does not know even of flexible exhaust system," he said.

The ancient Indian radar system was called rooparkanrahasya. "In this system, the shape of the aeroplane was presented to the observer, instead of the mere blimp that is seen on modern radar systems," he said

There were other claims made about India conducted a nuclear test centuries ago, and also that cow urine can cure diabetes and ancient India was adept at genetics and plastic surgery. These and more such incredible achievements datelined ancient India have come from votaries of Hindu culture.

Few Speakers at a prestigious science conference in Mumbai have said that a Hindu sage invented interplanetary spacecraft 7,000 years ago, that a herbal paste applied to a person’s feet can help locate underground water and that a bacteria found in cows can turn any material into gold.

The Indian Prime Minister Narendra Modi while speaking at the inauguration of a hospital in Mumbai in October too made such claims where he equated birth of Mahabharata's Karna to genetic engineering. He said, "We can feel proud of what our country achieved in medical science at one point of time. We all read about Karna in Mahabharata. If we think a little more, we realise that Mahabharata says Karna was not born from his mother's womb. This means that genetic science was present at that time. That is why Karna could be born outside his mother's womb."

At the same event, Modi also said, "We worship Lord Ganesha. There must have been some plastic surgeon at that time who got an elephant's head on the body of a human being and began the practice of plastic surgery."
