Vedas and ancient Indian science theories are often considered as the most advanced works in the world from their era. There are scientists taking who are fascinated by the knowledge of the ancient Indian scholars and dedicated their life researching on the ancient Indian Science 

1. THEY KNEW THE EXISTENCE OF SOLAR SYSTEM LONG BEFORE.

Veda Rig 1.35.9

“The sun moves in its own orbit but holding earth and other heavenly bodies in a manner that they do not collide with each other through force of attraction.

2.  THEY THEORIZED GRAVITY WAY BEFORE THE WESTERN WORLD.

The verse 10.22.14 of Rig Veda says

“This earth is devoid of hands and legs, yet it moves ahead. All the objects over the earth also move with it. It moves around the sun”

3. THEY KNEW THE SPEED OF LIGHT WAY BEFORE THE REST OF THE WORLD KNEW IT.

A Vedic scholar by the name of Sayana discovered the speed of light back in the 14th century AD.

His quote  which translates to

“With deep respect, I bow to the sun, who travels 2,202 yojanas in half a nimesha.”

A yojana is approximately 9 miles; a nimesha is 16/75 of a second.

So,  2,202 yojanas x 9 miles x 75/8 nimeshas = 185,794 miles per second which is remarkably equal to the actual value of 186 282.397 miles per second.

4. THEY KNEW THE SCIENCE BEHIND ECLIPSES WHEN THE REST OF THE WORLD WAS SCARED THINKING ECLIPSES ARE CAUSED BY SOME SORT OF BLACK MAGIC.

Rig Veda 5.40.5 has a phrase which translates to

“O Sun! When you are blocked by the one whom you gifted your own light (moon), then earth will be surprised by the sudden darkness.”

This is a remarkably accurate description of a solar eclipse.

The Vedas’ detailed descriptions of the universe, planets, and other phenomena demonstrates the vast knowledge of the people of those times far before modern civilization even started to exist.

5. THEY ACCURATELY PREDICTED THE DISTANCE BETWEEN SUN AND EARTH.

“Yug sahasra yojana par bhanu, leelyo taahi madhura phal jaanu” -Hanuman Chalisa The above verse written by Tulasidas in Hanuman chalisa translates to how “The Surya, situated thousands of Yojanas(a unit of distance) away was swallowed by Hanuman thinking it to be a fruit” Here 1 Yuga = 12000 years 1 Sahsra Yuga = 12000000 years. Also, 1 Yojan = 8 miles So, Yug Sahsra Yojan(the first three words) would mean 12000*12000000*8 = 96000000 miles. Converting it to kilometers, 96000000 X 1.6 = 153,600,000 kms Actual distance from earth to sun = 152,000,000 kms(error of around 1%

6. THEY MEASURED THE CIRCUMFERENCE OF THE EARTH.

Brahmagupta in the 7th century CE proposed that the circumference of the Earth to be 36,000 km, which is close to the actual figure of 40,075 km, with an error margin of 1%.
