The book tells about the history of the emergence of the concept of time and the associated paradoxes of the modern scientific picture of the universe. The amazing properties of space-time on the scale of the microcosm and the entire Universe are described. Theories of the birth of physical time in the turbulent processes of the emergence of the Big Bang singularity are considered. Modern cosmological scenarios, elements of the theory of relativity and quantum cosmology are presented in a fascinating and fascinating manner. The flow of time near gravitational collapsars - black holes, neutron stars, white dwarfs and quasars - is discussed. Popular hypotheses for the structure of hypothetical time machines are presented and cause-and-effect paradoxes in their use are analyzed. The author tried to draw the attention of readers to those contradictory phenomena of the surrounding objective reality, where everyday ideas about time change in the most unexpected way.
