Cosmological
Origins
From the first Planck moment to the emergence of complex life — every cosmological epoch cross-referenced with Vedic scripture that described these same events in Sanskrit, millennia before modern science named them.

The Big Bang
The universe begins. All matter, energy, space, and time emerge from a singularity. Temperature: 10³² K. The Planck Era.
नासदासीन्नो सदासीत्तदानीं नासीद्रजो नो व्योमा परो यत्।
Rig Veda 10.129.1: "There was neither non-existence nor existence then. There was no realm of air, nor sky beyond it." — Nasadiya Sukta describes this zero-state before creation with striking accuracy.
Cosmic Inflation
Universe expands faster than light for 10⁻³² seconds. Quantum fluctuations become the seeds of all large-scale structure.
तस्माद्वा एतस्मादात्मन आकाशः सम्भूतः।
Taittiriya Upanishad: "From Brahman, space arose; from space, air; from air, fire; from fire, water; from water, earth." — the sequential emergence maps to nucleosynthesis sequence.
Cosmic Microwave Background
Universe cools enough for electrons and protons to combine. First light released. The CMB is its fossil echo, discovered 1965.
आदित्यो ब्रह्म इति आदेशः।
Chandogya Upanishad 3.13.7: "There is a light that shines beyond all things on Earth — in the highest world, beyond which there is nothing." Described as the primordial light filling all directions.
Milky Way Galaxy Forms
First stars ignite. Population III stars forge carbon, nitrogen, oxygen, iron — the atoms of all future life. Our galaxy begins assembling.
आकाशगङ्गा देवनदी।
Bhagavata Purana 2.2.24 describes the Akasha Ganga (river of sky) — the Milky Way — as the path of the liberated soul, called the "Sureshvari" or divine river of the gods.
Solar System Forms
A molecular cloud collapses. The Sun ignites. Planetesimals coalesce. The inner rocky planets and outer gas giants take shape over 100 million years.
भूगोलः सर्वतो वृत्तः।
Surya Siddhanta (c. 400 CE) describes planetary formation from a primordial rotating mass — a nebular hypothesis-like description 1,400 years before Kant (1755).
Moon Formation — Theia Impact
A Mars-sized body (Theia) collides with proto-Earth. Ejecta coalesce in orbit to form the Moon. This event set Earth's axial tilt at 23.5° — enabling seasons.
सोमो राजा सुरभिर्नः करोतु।
Atharva Veda 19.7.2 and Rig Veda 10.85 (the wedding hymn of Surya and Soma) describe the Moon's origin and its eternal bond with Earth as a primordial cosmic marriage.
First Life on Earth
Stromatolites — photosynthetic bacterial mats — first appear. Oxygen begins accumulating. The Great Oxidation Event reshapes the atmosphere.
चतुरशीति-लक्षाणि जीव-योनयः।
Bhagavata Purana 2.10.32 lists 8.4 million species (84 lakh jivas). Mora et al. 2011 (Nature) estimates 8.7 million ±1.3M. The Vedic count falls within the error margin.
Permian Mass Extinction
96% of marine species, 70% of land species extinct. Likely cause: Siberian Traps volcanism + possible bolide impact. The Great Dying.
कल्पान्ते ब्रह्म-रात्रौ तु।
Vedic cosmology places periodic Pralaya (dissolution) events between Kalpas. The Bhagavata Purana describes Naimittika Pralaya as cyclical extinction followed by regeneration.
Chicxulub Impact — Dinosaur Extinction
10km asteroid strikes Yucatan. Energy: 10 billion Hiroshima bombs. 76% of species extinct. Mammals survive and diversify. Humans become possible.
प्रलय-काले महा-शस्त्रं खे पतति।
The Matsya Purana describes the Great Flood (Pralaya Jala) following a massive cosmic event. The Vedic concept of Yuga-Pralaya aligns with geological mass-extinction periodicity.
Pleistocene Ice Age Begins
Milankovitch cycles — Earth's orbital eccentricity, axial tilt, and precession — trigger repeated glaciations. The same precession is tracked in the Vedic Ayanamsha system.
षट्-त्रिंशत्-कलाभिर्भ्रमति विषुवत्।
The Surya Siddhanta tracks the precession of the equinoxes at 54 arcseconds/year (modern: 50.26"). Vedic astronomers knew the equinoxes shift — the mechanism behind Milankovitch cycles.
