We know Earth’s rotation on a cosmic scale, but seeing it close up requires quantum mechanics. Interferometry is the use of light waves, sound, etc., to identify changes in matter or motion. New ...

But in all likelihood, the Earth will not see this time, having been engulfed by the Sun in its red giant phase, around 7.6 billion years from now. In short, the Earth will not stop spinning, at least ...

Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

Every second, the Earth spins at an incredible speed, completing a full rotation in just 24 hours. While this may seem ...

Global warming has slightly slowed the Earth’s rotation — and it could affect how we measure time. A study published Wednesday found that the melting of polar ice — an accelerating trend driven ...

Earth’s Rotation Day 2026, observed on January 8, highlights how Earth’s constant rotation shapes day and night, climate, ...

The Earth is pretty good at keeping its pace. However, variations do happen. And on three separate days this summer—July 9, July 22, and August 5—the Earth will spin notably faster than usual. Of ...

Humanity's increased release of greenhouse gasses has raised the planet's temperature, and no one expects that to stop any time soon. As the globe warms, a study shows it is also spinning more slowly.

Earth's rotation is randomly speeding up, and nobody is quite sure why. These speedups, which have occurred several times over the last few years, haven't had any effect on daily life, but they also ...
