The Architecture of Time: The Vedic Yuga, the Western Clock, and What Physics Still Cannot Settle

This article examines time as three genuinely distinct frameworks, presented separately rather than forced into a single convergence narrative. It surveys the Vedic and Puranic conception of cyclical, beginningless time (kala, anadi), including the precise textual figures for the kalpa (4.32 billion years) and maha-yuga (4.32 million years) cycles, and Sri Yukteswar's alternative 19th-century reinterpretation of the Yuga durations. It surveys the Western historical shift toward linear time, anchored in Augustine of Hippo's theological argument against cyclical time, and its consolidation into the modern scientific and historical worldview. It examines the precise modern measurement of time, from the 1967 cesium-133 definition of the SI second through the zeptosecond (the shortest interval directly measured) to Planck time (the theorized smallest physically meaningful interval). It examines the genuinely unresolved scientific question of whether time is fundamental or emergent, reviewing the entropy-based 'Past Hypothesis' explanation for time's arrow, and devotes a dedicated section to loop quantum gravity, explaining precisely what the theory proposes about discrete spacetime, why physicist Carlo Rovelli specifically argues this supports treating time as non-fundamental, and the substantive academic pushback this claim has received. The article concludes by examining loop quantum cosmology's 'Big Bounce' proposal as a structurally distinct but independently interesting parallel to Vedic cyclical cosmology, explicitly avoiding the claim that the two are equivalent or that one validates the other.
