Abstract: Life after death theme attracted people attention for ages, being a question of faith or religion. Now the science tackles the matter in real earnest because of the so called “observer problem”. The study is devoted to the demonstration that consciousness remains alive continuously. Mathematical tools applied to the information phenomenon are used to prove this statement. During research, I made a conclusion that the number of information could be used as the characteristic of all the object and phenomenon and the number of information always larger than zero. Also, I agree that all our knowledge about any physical object are based only on its interaction width other objects include the light and our sense organs. As a mechanism of a eternal preservation of the man’s consciousness, I expect this is a nonlocal interaction. Yet to be explored, how the nonlocal interaction width elements of human body effects on the human self but even there are just has no effect, anyway there are impossible situation the man’s consciousness absolutely ceases to exist including the body’s physical death.
