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 ...

"The current rapid rise in day length can thus be attributed primarily to human influences," said professor Benedikt Soja.

The Earth is predicted to increase its rotation speed in July and August, once again bucking the trend of a slower rotation over time. Though there are clear reasons for the increased rotational speed ...

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 ...

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 ...

Polar ice melt caused by climate change is slowing the rotation of our planet at a rate never seen in the last 3.6 million ...

Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the ...
