Earth is spinning faster than ever, and the result is a shortening of the length of our days. Since 2020, each year has brought records for the shortest day ever, with Earth’s spin accelerating by ...

For the first time, researchers at ETH Zurich have been able to fully explain the various causes of long-term polar motion in the most comprehensive modeling to date, using AI methods. Their model and ...

Meltwater from the polar ice caps, combined with the shifting spin of Earth's core, is messing with the Earth's rotation to the point that we might need to adjust for a "negative leap second." The ...

Anyone who has ever said, 'There aren't enough hours in a day,' is in for a real treat! Scientists predict that one day, a day will last 25 hours. Experts say that Earth's rotation is slowing down, ...

• Timekeeping is determined by ultraprecise devices called atomic clocks, but it is also aligned with Earth’s rotation, mainly for historical reasons. • Because the planet’s rate of rotation ...

Although the Earth completes one full rotation in 86,400 seconds on average, that spin fluctuates by a millisecond or two every day. Before 2020, the Earth never experienced a day shorter than the ...

Aren’t the summer days supposed to be longer and the winter days shorter? Since when have things gone in reverse for the summertime? Since now, maybe? Starting today? Okay, here’s what’s going on.

On those three days, just over a millisecond is expected to be shaved off the standard 24-hour day. Of course, you're unlikely to notice such a miniscule difference in your day. But scientists who ...

On certain trans-Pacific flights, you can "time travel" by crossing the International Date Line. For example, if you want to go from San Francisco to Tokyo, and your flight departs at 5:00 p.m. on ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

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 is spinning faster this summer, making the days marginally shorter and attracting the attention of scientists and timekeepers. July 10 was the shortest day of the year so far, lasting 1.36 ...
