An international team of researchers said Sunday they will soon begin analyzing cosmic particles collected inside Egypt's Bent Pyramid to search for clues as to how it was built and learn more about the 4,600-year-old structure. Mehdi Tayoubi, president of the Heritage Innovation Preservation Institute, said that plates planted inside the pyramid last month have collected data on radiographic particles known as muons that rain down from the earth's atmosphere. The particles pass through empty spaces but can be absorbed or deflected by harder surfaces. By studying particle accumulations, scientists may learn more about the construction of the pyramid, built...
