Sun as Center of Solar System:
“He [The supreme source of light (Jyoti) upon the border of darkness he revolves, bringing into being, the creator of creatures] is denominated the golden wombed (Hiranyagarbha), the blessed; as being the generator.”
- Aryabhata also suggested in his treatise ‘Aryabhatiya’ that center of Solar System is the Sun. (Heliocentric)
- Vedic Works of literature have also referred the Sun as ‘center of spheres’. Thus heliocentric idea could have existed in the days of the Rig Veda around 1000 B.C. and was refined further by astronomers like Aryabhata and Varahamihira.
Spherical Shape of the Earth:
- In the Aitareya Brahmana (3.44) there is a verse describing the Spherical shape of Earth;
“The Sun does never set nor rise. When people think the Sun is setting (it is not so). For after having arrived at the end of the day it makes itself produce two opposite effects, making night to what is below and day to what is on the other side…Having reached the end of the night, it makes itself produce two opposite effects, making day to what is below and night to what is on the other side. In fact, the Sun never sets….” (English translation)
Nature of Gravity:
- In the text Surya Sidhantha, Bhaskaracharya described that “objects fall on the earth due to one force. The Earth, planets, constellations, moon and sun are held in orbit because of that one force.”
The existence of Other Stars:
- An ancient Sanskrit couplet also contemplates the idea of stars in the night sky being similar to Sun:
“Sarva Dishanaam, Suryaham Suryaha, Surya.”
How Earth look from Space:
|World Map (Upside down)|
|Depiction on the base of description from Mahabharat|
- During the War of Mahabharata Sanjay was giving live telecast of scenes of battle as Dhritarashtra was not able to see anything. (I don’t know how he was able to do it, but definitely not by Videoconference)
Dhritarashtra asked him to describe how the world looks like from space.
यथा हि पुरुषः पश्येदादर्– शे मुखमात्मनः– ।एवं सुदर्शनद्व– ीपो दृश्यते चन्द्रमण्ड– ले॥द्विरंश– े पिप्पलस्तत– ्र द्विरंशे च शशो महान्।।–(भी– ्म पर्व, महाभारत)
The speed of the light:
- 4th verse of the hymn 1.50 of the Rig Veda on the sun, says:
तरणिर्विश्वदर्शतो जयोतिष्क्र्दसि सूर्य |
विश्वमा भासिरोचनम |
taraNir vishvadarshato jyotishkrdasi surya |
vishvamaa bhaasirochanam ||
“Swift and all beautiful art thou, O Surya (Surya=Sun), maker of the light,
Illuming all the radiant realm.”
- Commenting on this verse in his Rigvedic commentary, Sayana who was a minister in the court of Bukka of the great Vijayanagar Empire of Karnataka in South India (in the early 14th century) says:
“tatha ca smaryate yojananam. sahasre dve dve sate dve ca yojaneekena nimishardhena kramaman.”
Which means “It is remembered here that Sun (light) traverses 2,202 yojanas in half a nimisha”.
According to Ancient texts 1 yojan = 9.09 miles
1 nimisha = 0.2112 second ½ nimisha = 0.1056 seconds
So we get (2202 x 9.09)/ 0.1056 miles per second = 189547 miles per second
1 mile = 1609.34 meters so Speed of light will be 303275454 meters per second i.e. 3×108mps while modern experimental value is 299792458mps.
This striking resemblance with theoretical value is amazing.
These were only a few Examples of Grand Scientific History of Ancient India.
Many great thinkers have also recognized the Advanced Ancient Indian Science;
- Carl Sagan, a famous astronomer, and a great thinker as well said in his book ‘Cosmos’;
The Hindu religion is the only one of the world’s great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths.It is the only religion in which the time scales correspond to those of modern scientific cosmology. Its cycles run from our ordinary day and night to a day and night of Brahma, 8.64 billion years long. Longer than the age of the Earth or the Sun and about half the time since the Big Bang.”
- Marquis Pierre Simon de Laplace, French Mathematician wrote;
Nevertheless the ancient reputation of the Indians does not permit us to doubt that they have always cultivated astronomy, and the remarkable exactness of the mean motions which they assign to the Sun and the Moon necessarily required very ancient observation.
- Louis Jacolliot, (1837-1890) French Government official in French India, and one-time president of Court of Chandranagar said
“The Hindu revelation, which proclaims the slow and gradual formation of worlds, is of all revelations the only one whose ideas are in complete harmony with modern science.”
