Modeling the Origin Story of the Elements

Written by: Sean M. Simoneau, [email protected], 865.241.0709 More than 1800 years ago, Chinese astronomers puzzled over the sudden appearance of a bright “guest star” in the sky, unaware that they were witnessing the cosmic forge of a supernova, an event repeated countless times scattered across the universe. Today, with more…
