A Conceptual Breakthrough in our Fundamental Understanding of Nature! RIDING ON A RAY OF LIGHT An endless array of questions plagued modern science for over a century: What is a photon? Why does light behave like a particle and wave at the same time? How does a photon transform into a particle of matter? How does matter exhibit gravity? How has our universe formed? What came before the big bang? And so on . . . Many theoretical scientists, experimental researchers, and even philosopher-scientists down the centuries have attempted to understand all the secrets of nature on a single principle which has been propitiously named the theory of everything, but there has been no actual success with any of the models presented so far! Here comes a working model based on a single theoretical principle which explains a wide range of phenomena from the structure of a photon to the structure of an atom to the origins of gravity to various intriguing phenomena of the universe, such as black holes, dark matter, dark energy and many such others! Perhaps the first consummate theory in the field of theoretical physics in modern times! Key Features of RIDING ON A RAY OF LIGHT A comprehensive guide to the workings of the universe! An academic treat to the science enthusiasts! A theoretical workbook to a scholar!
