Earth's magnetic field older than thought: Swiss breakthrough

ETH Zurich scientists reveal groundbreaking discovery about Earth's magnetic field existing over a billion years earlier than previously believed, using advanced computer simulations.

Key Takeaways

ETH Zurich scientists discovered Earth's magnetic field existed over a billion years earlier than previously thought
The research was conducted using complex computer simulations on the Piz Daint supercomputer in Lugano
An entirely liquid Earth core could generate a stable magnetic field before inner core crystallization
