Dark Matter Detector Observes Radioactive Decay of Xenon-124

A process that takes more than one trillion years, the age of the universe has been measured by researchers. The researchers used an instrument that is built to search for black matter (the most elusive particle that's known to man!).  An international team from the XENON Collaboration made public their observation of the radioactive decay of a substance that is called xenon-124, a form of an isotope, of the element xenon - a colorless, dense but odorless noble gas that’s found in trace on the Earth’s atmosphere.
