Gravity in Indian Knowledge Tradition
The concept of gravity, while scientifically formalized in the West by Sir Isaac Newton in the 17th century, has been subtly alluded to in ancient Indian scriptures and philosophical texts. Indian sages and scholars, through their keen observation of nature and cosmic phenomena, recognized the forces that govern the attraction between objects.
Key References to Gravity in Indian Texts:
Surya Siddhanta (Astronomy):
- Surya Siddhanta, an ancient astronomical text dated around 4th-5th century CE, provides insights into gravitational forces.
- It mentions that the Earth is self-sustaining due to its inherent force, which pulls all objects towards itself:
- "Bhu-kruti akrishya shakti," meaning Earth has a force that pulls objects towards it.
- This implies an understanding of gravitational attraction and explains why celestial bodies remain in their orbits.
Varahamihira (6th Century CE):
- In his work Panchasiddhantika, Varahamihira described the interplay of forces in the cosmos, hinting at an understanding of equilibrium and balance that governs planetary motions.
- He alludes to an invisible force binding objects to Earth, contributing to the early conceptualization of gravity.
Vaisesika Sutra (Philosophy of Atomism):
- Sage Kanada, the founder of the Vaisheshika school of philosophy (circa 6th century BCE), proposed theories about motion and the inherent tendencies of objects.
- He stated that objects fall due to their natural inclination (Swabhava), which can be interpreted as a precursor to the idea of gravitational pull.
Bhagavatam and Puranas:
- Texts like the Srimad Bhagavatam and other Puranas discuss the mutual attraction between celestial bodies, emphasizing balance and movement in the universe. These descriptions metaphorically hint at gravitational forces.
Philosophical Context:
Concept of Swabhavik Gati:
- Indian thinkers often described natural motion (swabhava) as a property inherent to objects. Objects tend to move or remain in equilibrium due to this intrinsic nature.
- While not explicitly detailing gravity as we know it today, these ideas resonate with modern understandings of forces like inertia and gravity.
Akasha (Ether) and Prana (Energy):
- The concept of Akasha (space) and Prana (energy) often explains the interconnectedness of all entities in the cosmos.
- This interconnection indirectly aligns with the concept of gravitational forces influencing celestial and earthly objects.
Comparison with Newtonian Gravity:
| Aspect | Indian Knowledge Tradition | Newtonian Science |
|---|---|---|
| Terminology | Akrishya shakti (pulling force) | Gravity (universal law) |
| Cause | Inherent nature (Swabhava); balance | Mass attracting mass |
| Scope | Philosophical and observational | Empirical, mathematical |
| Applications | Described in astronomical and cosmological contexts | Predictive models for motion and orbits |
Relevance Today:
The references to gravitational forces in Indian knowledge tradition reflect the depth of ancient Indian scientific thought. While not as mathematically explicit as Newtonian formulations, these insights show a sophisticated understanding of natural phenomena through observation and philosophical reasoning.
Modern researchers and historians often study these texts to appreciate the intuitive grasp of universal laws present in ancient Indian traditions.
