Summary

Story summary

Researchers at the University of Bern found Earth's primordial composition was complete within three million years of its formation, about 4.5 billion years ago.
They used manganese-53's radioactive decay to date Earth's chemical properties.
The study supports the Giant Impact Hypothesis, indicating a Mars-sized body, Theia, delivered life-supporting elements.
Early Earth lacked essential ingredients, likely introduced through later impacts.
Future research will model the collision event for further insights.
