For a while, core and the Earth's rotation matched. Later, the rotation speed of the Earth's core reduced even more until it started moving in reverse direction.

Earth’s inner core may have temporarily ... that seismic waves from nuclear tests show the inner core may reverse its rotation every three years or so. Meanwhile, other researchers have proposed ...

The rotation of Earth’s inner core may have paused and it could even go into reverse, new research suggests. The Earth is formed of the crust, the mantle and the inner and outer cores.

For a while, the scientists reported, the core’s rotation matched Earth’s spin ... and from 2008 to 2023 began moving slightly in reverse, relative to the mantle. For the new study, Vidale ...

The world is hungry for renewable sources of energy, which has led some scientists to ask the question: what about the rotation of the Earth? A new study reports that researchers have successfully ...

CNN — The rotation of Earth's inner core may have paused and it could even go into reverse, new research suggests. The Earth is formed of the crust, the mantle and the inner and outer cores.

A team of researchers from China believe the Earth’s inner core has reversed its rotation after they analyzed earthquake-driven seismic waves as they pass through the Earth. In a study published ...
