About gravity with quanta, about tachyons and quantum mechanics. A relatively simpler presentation and further development of the general theory of relativity and a foundation of quantum mechanics

In this book, it is shown that general relativity can be described in large parts with a four-dimensional force without an elaborated tensor calculus. It is demonstrated that gravity can be described with a system of equations similar to Maxwell's equations, with which one can explain the phenomena of dark matter and dark energy. It is demonstrated that gravity propagates with faster speed than light: Gravitons are tachyons, it is proven that the quantum effects of quantum mechanics are essentially co-determined by the quantity of faster-than-light gravitons, and it is shown that de Broglie's guide wave is formed by faster-than-light gravitons.
