Zeptosecond Birth Time Delay of a Photoelectron Determines Exceedingly Small Quantum Time Kshana or Moment

Kshana, or moment, is an exceedingly small, indivisible, and constant quantum of time defined by Maharishi Vyasa in his commentary on Patanjali Yogdrashan. The determined value of the number of kshana n using the concept of birth time delay Tb in the photoionisation process confirmsthe value of the number of kshana n in a second, as determined by the authors previous values. Kshana is even smaller than the experimentally observed zeptosecond birth time delay of photoelectrons in photoionization. Kshana, or moment, is not merely a theoretical concept. It is an experimentally measurable time in the future, and it may be used as a unit of time measurement at the subatomic level in physical science that studies non-living systems, matter, energy, and the fundamental laws of nature.
