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.
The geography of India, with its vast mineral resources, diverse plant and animal life, favorable climate, and sound social ethics of the people provided material prosperity to the region and fostered the intellectual endeavors of the Hindus.
1. The existence of solar system.
Rig Veda 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. Theory of gravity.
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. The speed of light.
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. The science behind eclipses
Rig Veda 5.40.5 has a phrase which translates to
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.
When the rest of the world was scared thinking eclipses are caused by some sort of black magic, ancient India knew the science behind it.
5. The accurately predicted distance between Sun and Earth.
Yug sahasra yojana par bhanu, leelyo taahi madhura phal jaanu
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%)
How cool is that??
6. 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%.
7. The estimated Length of an Year.
Surya Sidhhanta speaks of 4 ways to measure the length of an year namely "Nakshatra", "Savana", "Lunar" and "Saura", of these The Saura method accurately estimates the length of year to be 365 days, 6 hours 12 mins and 30 seconds.
If you are still wondering how they could do it go and visit temples at Konark or Humpi where you will find the incredibly complex and technically correct architecture systems of the temples that use the sunlight to measure the length of the day and year.
8. The value of Pi (π).
Aryabhata worked on the approximation of value of pi and came to the conclusion that is irrational and is approximately 3.1416 in 499 CE when he was 23 years old.
He can be considered as one of the smartest brains of ancient India because because the irrationality of pi was proved in Europe only in 1761 by Lambert. Not to mention, he even derived the values of sine & cos and gave birth to the concept of trigonometry.
9. They Theory that earth is a sphere.
Although the discovery of Earth being round is credited to Greek astronomers.
Interestingly, Indian astronomers had already claimed that Sun is a star and that earth is spherical long before the Greeks. It is documented that various attempts had been made to measure the circumference of earth during the Vedic periods. Aryabhatta deduced a formulation which proves that the Earth is rotating on an axis. By estimating the value of pi to be 3.1416 he deduced the circumference of earth to be 39736 Kilometers which is only 100 kilometers below its true value. In fact, in his book Aryabhatiya, he also asserts that the movement of heavenly bodies like the sun, the stars are all relative,
and only earth is moving. Just as a passenger in a boat moving downstream sees the stationary (trees on the river banks) as traversing upstream, so does an observer on earth see the fixed stars as moving towards the west at exactly the same speed at which the earth moves from west to east.

10. Worlds first underground drainage system.
Indus valley civilization designed the worlds first Underground sanitation system back in 1300 BCE which was adopted by the rest of the world centuries later. They are also the first civilization to create modern
11. The concept of surgical procedures.
They theorized and actually implemented the concept of surgical procedures using surgical tools centuries before the rest of the world.
The Sushruta Samhita written by Sushruta is the earliest medical encyclopedia known to world being written during 1200BC containing 184 chapters contains descriptions of 1,120 illnesses, 700 medicinal plants, 64 preparations from mineral sources and 57 preparations based on animal sources. You name a disease and it has a
chapter on it. It was announced in a scientific journal that the oldest and the first evidence for the drilling of human teeth of a living person was found in Mehrgarh. Eleven drilled molar crowns from
nine adults were discovered in a graveyard in Mehrgarh that dates from 7,500-9,000 years ago. A few evidences of orthopedic surgeries were also found concluding that ancient India had the technology to implement
surgical procedures. Anesthesia was made using herbs in Ayurveda.
12. Nikola tesla took inspiration from Swamy vivenakanda and Indian vedas for his world acclaimed work.
After his lab was burned down and his life's work had vanished. Nikola Tesla studied the concept of Prana and Akasha to work on FORCE and MATTER. He developed a new perspective on the world and started viewing world in
terms of frequencies and energy which resulted in him establishing his concepts on energy.
We intended to write this article not to take sides or argue against anyone's beliefs but only to give a small
idea on the intensity of the knowledge and imagination of our ancestors.
They even had the concept of sustainable energy, projectile science, and many others like Thrust, momentum,
Thermodynamics , Astrophysics etc to name a few.
