This is N. Mariori’s twentieth first book which was publised for the first time in 1989. In it, the existence of the invisible or according to the science, of the fourdimensional world, is narrated in a scientific way.
   In its scientific and mysticist pages, the scientists of our times parade (the nuclear physicists) and the great mystics who knew the other or the fourdimensional world, countless years ago, which the nuclear scientists just discovered.
   The announcement beforehand and the teaching of the other (spiritual) world are proved indisputably by the mystics and its recent groping by the scientists through their experiments in the Microcosm (accelerations - cyclotrons) and in the Macrocosm (black or white holes, netrina, etc.)
