Book Description

This book is unique and exceptional in any recent literature that deals with the notion of physical time rigorously, both logically and empirically. The central theme is the intimate relation between physical time and cosmic gravity. It establishes and explains, in an accessible and systematic manner, the one crucial physical fact that has been missed in the development of modern physics—that the enormous gravity of the matter and energy in the universe is the entire controller and cause of the relativistic flow of time. The material in the book is accurate and free of the ambiguities and imprecision that is common in the discussion of time and its modifications (dilation), synchronization of clocks, and simultaneity. The contents go beyond the current theories of relativity that fail to incorporate the cosmic gravity in their structure. The discussion of clocks in satellite navigational systems is the most complete and accurate. The book offers several new insights and results about physical time, and it is the only available treatise on the complete physical truth about time. The contents are addressed to a wide range of readers, from general readers to experienced researchers in physics, metrology, and precision chronometry. The content appeals well to philosophers and historians of physics as well. This book has the enabling quality, to deal with difficult questions about physical time, with unprecedented clarity and without paradoxes.

Biography

C. S. Unnikrishnan is professor of physics at the Tata Institute of Fundamental Research (TIFR), Mumbai, India. His research interests are experimental and theoretical aspects of fundamental issues in gravity and quantum physics, and novel metrology. His early work was in the precision tests of modified gravity and related instrumentation. He was a visiting scientist at the Kastler-Brossel Laboratory, Paris, where he participated in the Bose–Einstein condensation of metastable helium. He set up the laser-cooling laboratory at TIFR, in which the first Bose-condensate in India was produced and studied. Prof. Unnikrishnan’s major original contribution is the paradigm of cosmic relativity, a theory of relativity and dynamics based on the factual gravity of the matter in the universe, supported by many experimental results. Recently, he formulated a completion of Hamilton’s action mechanics to a universal mechanics, applicable to all scales of matter and dynamics, solving the foundational physical problems of quantum mechanics. Prof. Unnikrishnan is a proposer-member of the Laser Interferometer Gravitational-Wave Observatory (LIGO)-India project and a member of the global LIGO Scientific Collaboration that detected the gravitational waves. His major interests outside physics research are music and films, especially their structure and the process of their creation.
