In this book, Tantawi Gohary takes us on a profound philosophical journey that blends science, religion, and human thought, discussing the issue of "universal peace" as the greatest aspiration of humanity. The book is framed as a unique dialogue with a spirit coming from Halley's Comet, posing questions about humanity, its sciences, ethics, and higher classes. The author responds with answers based on cosmic laws, natural systems, and astronomical orbits. The book is not merely a philosophical discussion; it is a universal human message calling for the rejection of division and a return to the essence of pure humanity. This is why the Scientific Committee of the General Races Congress in England in 1911 approved and discussed it, and authorized its translation into several languages. It is a pioneering work that reflects a cosmic vision ahead of its time and an eternal call for peace and unity among humanity.
