New research suggests most of Earth’s heavy metals were spewed from a largely overlooked kind of star explosion called a collapsar. That gold on your ring finger is stellar – and not just in a complimentary way.
In a finding that may overthrow our understanding of where Earth’s heavy elements such as gold and platinum come from, new research by a University of Guelph physicist suggests that most of them were spewed from a largely overlooked kind of star explosion far away in space and time from our planet.
Some 80 per cent of the heavy elements in the universe likely formed in collapsars, a rare but heavy element-rich form of supernova explosion from the gravitational collapse of old, massive stars typicall...
