Pyramid power

摘要

Archaeologists have failed to learn the secrets of Mexico's largest ancient monument. Particle physicists might save the day, says Michael Hopkin. It's not the kind of place you'd expect to find a particle-physics laboratory. The ancient Pyramid of the Sun at Teoti-huacan is an hour's drive from Mexico City at the end of a bumpy jeep track. But deep inside this massive monument a state-of-the-art particle detector is being assembled, and my companions, both physicists, have brought me here to see how it's getting on.
