Earth’s inner core rotation slows, reverses every 70 years: Study

[Rudy]

Newly corroborated research suggests the rotation of Earth's innermost core has slowed down so much it's now moving backward, part of a larger pattern of changing speeds and trajectories.

The rotation, direction and pace of Earth's solid metallic inner core have divided scientists for decades, as it's impossible to observe or sample it directly. In that back-and-forth, countless models have projected what might be going on inside our planet.

New research published June 12 confirmed the core's slowdown and seems to support a model, first published in 2023 in Nature, that posits the earth's inner core has begun moving backward as part of a cyclical shift.
