I will assume you're referring to what would happen if Earth stopped rotating all at once, without any gradual reduction in velocity. In that event, most things on Earth would be almost immediately ...

As if it's not already hard enough to find the time to do everything you need to do in a day, now you're about to lose another whole millisecond or more. In fact, experts say Tuesday, July 22, could ...

Earth's inner core, once rotating faster than the surface, has begun to slow, impacting day length by fractions of a second. This subtle shift, detected through seismic wave analysis, reveals complex ...

Planet Earth is spinning a little faster today — resulting in one of the shortest days of the year. But the change will be so minuscule you won’t even notice. We’re talking even less time than the ...

Scientists announced Monday that Earth is rotating slightly faster than normal, resulting in what is expected to become the second-shortest day ever recorded since precise atomic timekeeping began.

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. After a few years of speeding up, our planet now appears to ...

When we think about a day on Earth, we usually take it for granted that it lasts 24 hours. But in reality, Earth’s rotation is a bit different. It’s not fixed, and over time, even tiny shifts in how ...

A new study confirms that Earth's inner core has been rotating more slowly than usual since 2010. This mysterious "backtracking" could also end up slightly altering the planet's overall rotation, ...

WASHINGTON — Wednesday will be slightly shorter than usual, but you probably won't notice the difference even if you're watching the clock closely. Earth is expected to complete a full rotation on ...
