The late German-Bolivian scholar Professor Arthur Posnansky dedicated nearly half a century to studying the ruins of the ancient city of Tiahuanaco, revealing a stunning historical mystery. He utilized the astronomical principle of the obliquity of the ecliptic to hypothesize that the construction date of the Kalasasaya Plaza may date back as far as 17,000 years ago. The obliquity of the ecliptic refers to the angle between the Earth's orbit and the celestial equator, which changes over time with a cycle of approximately 41,000 years.
To grasp this complex astronomical concept, imagine the Earth as a ship whose axis tilts as it orbits the Sun, leading to variations in the obliquity of the ecliptic. Posnansky inferred the angle at which the Kalasasaya Plaza was built by observing the changes in the positions of sunrise and sunset, arriving at a conclusion of 15,000 BC. This discovery challenges traditional historical perspectives and sparked a heated debate within the scientific community.
From 1927 to 1930, a team of astronomers, including Dr. Hans Ludendorff, director of the Potsdam Observatory in Germany, and Dr. Friedrich Becker from the Vatican Observatory, conducted an in-depth study of Posnansky's theory, ultimately confirming that his findings were fundamentally correct. Their conclusions not only validated the ancient origins of Tiahuanaco but also raised numerous speculations about its builders and their intentions.
