Ancient high technology has been discovered that used Super acoustics to alter consciousness and affect both physiological and psychological changes on those subjected to it. Recent studies have shown that the frequencies detected within the Oracle Chamber in the Hal Saflieni Hypogeum have a physical effect on human brain activity. The Hal Saflieni Hypogeum is located in Malta. It is the oldest underground temple in the world and it's a UNESCO World Heritage site. Dating back to the neolithic period it is over five thousand years old, making it older than the Egyptian Pyramids and even Stonehenge. This amazing subterranean complex is three levels deep, with each level superimposed over the other and it shows an incredible understanding of advanced engineering. That this was all accomplished over five thousand years ago is beyond astounding.
