Early universe was far less pristine than scientists thought

New research suggests the earliest universe was not as chemically clean as long assumed. Scientists had believed the first stars and galaxies contained almost only hydrogen and helium, with heavier elements forming slowly over billions of years. The finding indicates heavier elements appeared far earlier than expected, prompting astronomers to rethink models of how the first stars formed and evolved.
Why now: New astronomical findings challenge the standard model of how quickly heavy elements formed after the Big Bang.
