Mahabharata Era

Oak dates the Mahabharata war to October 16 – November 2, 5561 BCE — the most evidence-dense dating proposal for any ancient event. He tests 215+ astronomical references from the Mahabharata text simultaneously using Voyager 4.5 and Stellarium. The Arundhati-Vasishtha observation — describing star Alcor walking ahead of Mizar (Mahabharata, Bhishmaparva 2.31) — alone eliminates every proposed date after 4,508 BCE, falsifying 96%+ of all competing proposals including the traditional Kali Yuga date (3102 BCE) and Achar's 3067 BCE.

Bhishma Nirvana (2018) independently corroborates the date with 300+ additional observations. The Saraswati's condition described in the Mahabharata — a flowing but diminished river — matches geological evidence for the river at ~5,500 BCE: monsoon rejuvenation after 9,000 BCE sustained flow, but the river was past its glacial-fed prime.

Krishna's Dwarka was submerged approximately 36 years after the war (~5,525 BCE). Post-glacial sea levels were still rising at this date. S.R. Rao's underwater campaigns found submerged structures off the Gujarat coast, though the TL-dated structures (16th century BCE) may represent a later settlement.

The archaeological challenge: Mehrgarh at 5,561 BCE is a small farming village with mud-brick houses — not a kingdom with chariots and armies. Oak's response: most archaeology has focused on the mature Harappan period (~2,600 BCE), and the Saraswati basin remains largely unexcavated at pre-Harappan depths.
