A team of geophysicists has demonstrated that Earth's magnetic field could have originated even before the planet's solid inner core formed. The new research from ETH Zurich and SUSTech, China, addresses a long-standing question in geoscience by using high-fidelity computer simulations to test conditions present over a billion years ago. According to the well-established dynamo theory, the
