ScienceEarth’s internal gravitational tug-of-war may explain small changes in day length
Nature reports that a study finds competing forces driven by the motion of Earth’s core can explain small variations in the planet’s rotation.

Nature reports that a gravitational tug-of-war driven by the motion of Earth’s core can explain small variations in its rotation and the length of our days. Nature says the finding suggests geophysicists could be on the right track to understanding mysterious structures deep inside Earth.
