He was considered a student of Nikola Tesla. His name was Andrija Puharich. Over the years, Puharich became known as a controversial researcher working on unusual experiments involving frequencies, the human brain, and electromagnetic signals. He also collaborated with various scientific and government institutions and, according to several sources, worked on projects connected to the CIA. In his lectures, Puharich made a series of remarkable claims about Tesla’s research — suggesting that some of Tesla’s discoveries did not disappear after his death, but were studied and developed further by major world powers. He spoke about experiments involving signals traveling through the Earth, frequencies capable of influencing biological systems, and technologies that could interact with the human nervous system in ways most people would find difficult to imagine. In the footage shown in this video, Puharich describes these ideas in his own words. Whether these statements represent misunderstood science, speculative theories, or something more serious is still debated today. But one thing is certain: the implications of what he suggested are far more unsettling than most people realize.
