This unusual publication shows all the evidence leads to the fact our planet, and most probably all celestial objects of the galaxy, are going through an unending natural growing process. The evidence of planet Earth's growth is irrefutable yet its acceptance involves, since it would not grow otherwise, the absolute hollowness of the orb. According to the authors' thesis most probably all planets, moons (Yet there is disturbing evidence demonstrating our moon is most likely an artificial object) and stars are going through similar expansive process as well. By logic expanding hollow objects eventually would brake apart but the growing process of a hollow object, according to the authors, implicates fresh matter is naturally and continually produced. Interestingly the famous artist Neal Adams had independently proved the growing Earth process must have slowly but surely led to the dinosaurs' extinction. This is a sober twelve-year in the making, well-researched and well-written, illustrated publication.
