The design of the Paradox seeks to line up that point with another wonky physics term, the “principal axis of inertia.” Basically, a rigid body like a putter rotates in three primary axes ...

On July 9, 2025, scientists at the International Earth Rotation and Reference Systems Service (IERS) reported that the Earth ...

The science behind why the Earth will spin just a little bit faster on July 9, July 22, and August 5, this year.

Earth takes just under 24 hours to complete one rotation. But the movement of its axis, and therefore its poles, could add milliseconds to that spin time, making our days a tiny bit longer.

When the Earth’s ice masses melt, the way the planet rotates also changes. Researchers at ETH Zurich have now been able to show how climate change is altering the Earth’s axis of rotation and the ...

You might not be able to feel Earth’s rotation, but it’s spinning on a north-south axis at a rate of about 1,000 miles per hour (1,609 kilometers per hour).
