Modern psychological science is convinced that consciousness and psyche do not exist without the brain. The material basis of the human psyche is the nervous activity in the human brain. It can be said that the psyche is a function of the brain. Mental activity results from physiological activity in the human brain. Such understandings are generally accepted throughout the scientific world. It should be noted here that the terms ‘psyche’ and ‘consciousness’ are not synonymous. The concept of psyche is much broader than the concept of consciousness, including the conscious psyche as one of its parts. However, the concept of consciousness itself is not unambiguous, which means that there are many different approaches and emphases in its scientific definition. Scientific psychology classifies mental phenomena into three broad groups: mental processes, mental states, and mental properties. Consciousness and psyche are not the same. Psyche is a broader concept than consciousness. It can be argued that consciousness, memories and also attention are parts of the psyche. Psyche is the broadest term to define human behavior and its causes. Psyche is studied by psychology, but consciousness is studied by the science of consciousness, which is a part of psychology. Consciousness and attention were once thought to be one and the same, but they too are actually separate parts of the psyche, albeit closely related. In higher vertebrate life forms, the nervous system is very highly differentiated, such as in birds and mammals. The signs of such life forms indicate that their behavior is conscious. However, their characteristic behaviors are absent at all or present only partially (which can also be vague) in such life forms whose nervous system is not so highly differentiated. From this, science concludes that consciousness is related to complex neuron structures. This implies that consciousness does not exist outside of neuronal structures. Science accepts that consciousness exists only in cooperation between cortical and subcortical structures, not in either structure alone. However, there are phenomena in medicine that refute the notion that consciousness (psyche) cannot exist without a brain. Such phenomena, called near-death experiences, or NDEs for short, are studied by the out-of-body physics theory. Most accounts of near-death experiences clearly show a combination of near-death and out-of-body experiences. Neuroscience has tried to explain these two aspects separately, rather than linked together. But in the case of Pam Reynolds, for example, these phenomena still occurred together, not separately. A person's out-of-body experiences and near-death experiences cannot be taken quite one for one. A person's out-of-body experience involves only leaving the body and nothing else. At the same time, however, the near-death experience includes many other aspects besides leaving the body, such as seeing the "souls" of the dead, a tunnel of light, beautiful landscapes, and a feeling of bliss. A near-death experience includes an out-of-body experience, but it is a much broader and more diverse phenomenon than just an ordinary out-of-body experience. In that sense, they are two phenomena of somewhat different depth and reach. The physics theory of the human exiting the body describes and studies the real possibility of the human disembodied state, which is the first part of the super-civilization theory, or ÜTT. The second part describes and examines the impact of a person's disembodied state on society and civilization as a whole. The physics theory of the human disembodiment is based on the physics theory of time travel, but the supercivilization theory is based on the physics theory of human disembodiment. The research methods of the disembodiment theory are typical of theoretical science, as there is no possibility of direct observations or experiments, which are otherwise the basis of any scientific field. Theoretical science is based on argumentation. Therefore, this field is similar to theoretical physics. Strictly speaking, the physics theory of human disembodiment is a scientific field at the intersection of neuroscience, psychology, and theoretical physics. Thus, it is a frontier science that is difficult to verify experimentally. For example, string theory is a branch of physics that studies and describes the material world in 11-dimensional spacetime. It belongs to the field of theoretical physics and is thus a scientific field of study, even though experiments and observations cannot be made directly in string theory. The physics theory of human disembodiment studies and describes the real possibility of a human disembodied state that does not contradict existing experimentally proven physical theories. In order to understand the exit from the body, a whole series of new theoretical understandings of physics are created, based on which it is possible to conduct experiments to prove them in the future. This work presents the most basic discoveries, understandings and positions of the physics theory of human disembodiment and the resulting super-civilization theory, which have been arrived at during a long and thorough investigation. However, it must be emphasized that this work is still in an overview or introductory format, as the theoretical concepts described are actually much more voluminous, complex and nuanced than it appears at first glance. Despite this, the current work provides a good and comprehensive overview of the basic content of the physics theory of human disembodiment and the nature of the supercivilization theory. In the beginning, a great deal of emphasis is placed on refuting brain-centered theories, but it smoothly transitions to an alternative out-of-body explanation, which describes the possibility of a person's disembodied state as an electromagnetic field in the outer dimension of spacetime.
