Kalpa and Pralaya: TimeScales Corresponding to Major Cosmological Events - A Concept Paper

CA Krishnamurthy Ramakrishnan

Abstract: Indian Cosmology describes Cosmic Cycles and Brahma as the Creator of the Universe. A Day of Brahma is called Kalpa and is 4.32 billion years. A Night of Brahma is called Pralaya and is also 4.32 billion years. The Concept Paper examines whether there were significant cosmological events during Brahma's Day and reduced cosmological activity during Brahma's Night. Taking the Big Bang as a starting point and that the Universe is ~13.7 billion old, there have been two complete Kalpas and one complete Pralaya and the Universe is now ~760 million years into the second Pralaya. The Concept Paper attempts to correlate significant cosmological events during a Kalpa and reduced cosmic activity during a Pralaya. While there does seem to be a correlation, given that there have been only two complete Kalpas and one complete Pralaya, the concept needs more research to definitively establish a correlation.
