A full understanding of the universe must encompass the three worlds of matter, mind and spirit, as well as building bridges between them. While physics has been remarkably successful in describing the material world, from the smallest scales of particle physics to the largest scales of cosmology, it currently makes no reference to consciousness and associated mental or spiritual experiences. Indeed, most physicists adopt a materialist and reductionist view in which consciousness is just an incidental by-product of the brain. However, many arguments from physics itself suggest that consciousness is a fundamental rather than incidental feature of the Universe, so it is natural to extend physics to accommodate it. This is especially true if one believes in certain anomalous interactions between consciousness and the physical world. However, this will require a radically different physical paradigm from the one that currently prevails. 2021.
