This article shows how string theory is able to model nonphysical particles and how three-dimensional string theory “branes” (parallel universes) could hold dark matter and dark energy. Introspective experience from scientifically oriented groups gives us some clues of how
the mind and consciousness could be described. The resulting synthesis from science and direct introspection, for understanding mind and consciousness, are presented. It shows a cosmos with: (1) A parallel nonphysical universe containing dreams, thoughts, emotions, and memories. This universe,
called the psychological universe, is probably based on dark matter; (2) A parallel nonphysical universe where intuitive nonphenomenal thinking takes place and where personality and worldview are stored. This universe is called the intuitive universe and is probably based on dark energy and
seems to have quantum mechanical qualities. These two universes together make up the mind such as it is defined in this article; and (3) A third nonphysical universe filled with negative energy could make up consciousness. All four universes (including the physical universe) have different
vacua, dimensions, and energy levels, so they are all around us but separated. I propose that biological beings consist of a physical body in the physical universe plus entangled bodies in the three nonphysical universes. Entanglement is established by signals going both ways between the different
bodies. String theory shows how the interaction between branes/universes can take place. Such a worldview seems to match the requirements from string theory so that it becomes a theory that includes the physical universe and the mind (all kinds of positive energy), and the connection to consciousness.
Consciousness itself is based on negative energy, according to mathematician Luigi Fantappiè. The physical base for negative energy is still an open question.
