The Cosmic Microwave Background (CMB), the oldest light in the universe, provides a blueprint that confirms the necessity of dark matter and dark energy. To find the physical particle, researchers have engaged in the "Xenon Wars," utilizing massive underground detectors like those at Gran Sasso in Italy. These detectors wait for a dark matter particle to collide with a xenon nucleus, but they have so far produced only null results. One exception is the DAMA experiment, which claims to see a seasonal variation in detections as Earth moves through the galactic dark matter halo, though other teams have been unable to replicate this. Additionally, the Alpha Magnetic Spectrometer (AMS) on the International Space Station searches for antimatter that might be created by dark matter collisions in space. The lack of definitive detection in these high-tech experiments is increasingly puzzling for the scientific community. (7/8)1957
