The Concept Gravity pulls objects towards the centre of the Earth. It explains why apples fall instead of drifting away. It is the glue that keeps the cosmos together.
The Story Long before Sir Isaac Newton watched an apple fall in 1687, the sages of India were pondering why the world didn’t simply drift apart. While the Western world was still debating whether the Earth was flat or held up by giants, Rishi Kanada and later Brahmagupta identified an invisible “pull”. Brahmagupta famously noted that it is as natural for the Earth to attract bodies as it is for water to flow. They called it Gurutvakarshan—the attraction of the weighty. Centuries before the “Scientific Revolution,” Indian thinkers had already realized that we aren’t just standing on the ground; we are being held by a cosmic embrace .

The Original Text
Sanskrit Shloka: आकृष्टिशक्तिश्च मही तया यत् खस्थं गुरु स्वाभिमुखं स्वशक्त्या । आकृष्यते तत्पततीव भाति समे समन्तात् क्व पतत्वियं खे ॥
Transliteration: Ākṛṣṭiśaktiśca mahī tayā yat khasthaṃ guru svābhimukhaṃ svaśaktyā | Ākṛṣyate tatpatatīva bhāti same samantāt kva patatviyaṃ khe || (Siddhanta Shiromani, Goladhyaya – expanding on Brahmagupta’s concept)
Meaning: “The Earth has attractive power (aakrishti shakti). By this power, it pulls heavy objects in the sky towards itself. Because it pulls, things appear to fall.”
Related Innovations The Vaisheshika Sutra (before 5,000 BCE) distinguished between inherent mass and weight, a force caused by gravity (Gurutva).
Fun Fact Aryabhata described the way the Earth floats amidst the stars, held there by its own force. This contradicted the flat-Earth dogma of the day in the West.
The Modern Legacy Gravity is the most crucial factor in rocket science, civil engineering, and understanding how black holes work.
