This book predicts anti-gravity made by a rotating black hole, which expands the universe, as well as a mechanism of a flying craft having a disk-shaped body for interstellar travel. The gravitational waves emitted from the black hole are also predicted. They can indicate the presence of the source, the black hole or the flying craft, having physical properties such as energy intensity and spin angular momentum. As a part of the simulation, the mechanism of a time machine is also described, which reverses the past and the future. With this mechanism, humans may observe the projected images of...
