Description:Musings on Light has been written at the end of a journey. This journey involved a mathematical articulation of the power in light summarized in ten books across two Cosmology of Light book series. It is a contemplative, primarily non-mathematical summary of many of the key concepts that are contained in the ten Cosmology of Light books. I intended for these musings to be meditative and to assist the reader to intuitively grasp what is meant by Cosmology of Light. To further assist with the meditation, each of the musings of which there are 50, is accompanied by a carefully designed illustration that will further allow the reader to enter more deeply into the body of Cosmology of Light. Cosmology of Light is intended to be a unified theory of existence from the point of view of light. Hence, it ties together possibility that exists in the native state of light where it is imagined to exist infinitely fast, to the process of multiple quantizations by which light projects itself in layers mirroring symmetrical fourfold realities, to the emergence of space-time-energy-gravity as a cosmic container at the time of the big bang, to the emergence of matter and life in layers of quantum particles, atoms, and cells, to the emergence of humans and culture and civilizations, so that physics, chemistry, biology, psychology, and sociology are all seen as faces of the one body of Light, always behind, immanent in all, and of which all are only richer and richer expressions.
