The physical plane (also known as a hyperplane), physical world, or physical universe, in emanationist metaphysics such as are found in Neoplatonism, Hermeticism, Hinduism and Theosophy, refers to the visible reality of space and time, energy and matter: the physical universe in Occultism and esoteric cosmology is the lowest or densest of a series of planes of existence (hyperplanes that are said to be nested).
