The Key of Time – Armando Mei Preface by Billy Carson, bestselling author and world-renowned researcher of ancient mysteries In The Key of Time , Armando Mei leads the reader on an extraordinary investigation into the roots of archaic knowledge, unveiling a revolutionary perspective on the origin of sacred measurements in Ancient Egypt. At the heart of this groundbreaking work lies an innovative interpretation of the Egyptian cubit—not merely as a linear unit of measurement, but redefined as a circular unit intrinsically linked to the cyclical conception of time and space that characterized divine civilizations. Through a rigorous and multidisciplinary analysis, Mei connects the Egyptian cubit to the enigmatic number 137 , a fundamental constant in modern physics, suggesting the existence of an angular measurement of the gods : a sacred-mathematical code that governs the spatial arrangement of the monuments on the Giza Plateau according to cosmic laws. But what makes this edition even more exceptional is the exclusive preface by Billy Carson —bestselling author, media personality, and one of the leading experts on the mysteries of the past. His contribution frames Mei’s research within a broader vision, making this book a must-read for anyone fascinated by ancient civilizations, sacred science, and the eternal enigma of Giza. The Key of Time is not merely a work of alternative archaeology; it is a profound journey into the codes of time —one that challenges the foundations of official historiography and opens new pathways to understanding the relationship between humanity, divinity, and the cosmos. A compelling and authoritative read for those who dare to question the ultimate meaning of Giza’s eternal stones.
