Theory, with suggested experiments, that our four-dimensional universe (3D space + time) is a "special case" of a five-dimensional reality called the trans-light state. This would be the state of existence which prevails once the light barrier has been broken.
The site is written in the style of a text book, presenting every step and allowing a student to follow it through, understand it and know if it is right or not. The presented theory says that the gravitational field has origin in annulations of the electromagnetic field, i.e. that electromagnetic fields transmute to gravitational one.
A mistake is found in electrodynamics: under transverse motion of a magnet the vortex electric fields can be unclosed and the flow of induction through a closed surface can be nonzero.
