The Tathagatha the Enlightened Buddha Gautama in his first watch of Night found that Universe evolve in a Four Incalculable duration of time that is in four Asankeyyas. Here it was proved using modern Physics and Mathematics. They are the new principles of Physics and Mathematics content of New Philosophia Naturalis Principia Mathematica. One Incalcalculable or Asankeyya is equal to the ten to power hundred and fourty earth years and Deuteron takes that much age in it's decay. Siddhartha Gautama in his enlightenment could recall one lakh former births and many Aeons of world expansion and contraction. Buddha Gautama took four incalculables to achieve the Buddhahood the full enlightenment or samma sambodhi. Pratayeka Buddhas can recall up to two incalculables,one lakh past births only. Chief disciples of Gautama the Sariputta and Moggalana can recall one incalculable and one lakh past births only. Arahants can minimally recall up to fourty births of their past life.This book discuss those aspects using modern physics and mathematics. When Max Planck discovered the quanta of energy it was said physics come to and end in this text it has been proved. A.C.W.L De Alwis is the author.
