Physicists at NASA and Princeton generate electricity from the Earth's rotation: could wind energy be our energy source of ...

A Dec. 5 Instagram post (direct link, archive link) shows a TikTok in which a man reads and shows screenshots from various NASA reports that reference a "flat, non-rotating earth" model. "NASA ...

For nearly a billion years, Earth’s rotation stopped slowing down. Locked in a rare cosmic balance, the planet’s day remained ...

Scientists recently discovered that Earth’s dense inner core may have stopped rotating relative to the surface. But that change is not likely to have noticeable impacts on our daily lives. Scientists ...

Earth takes 24 hours to complete a full rotation in a standard day, equal to exactly 86,400 seconds. July 9 was the first of three days in which a millisecond or more could be shaved off the clock on ...

The inner Earth is a mysterious place, and now scientists may have uncovered a strange new secret. According to a new study, the Earth’s inner core may have recently stopped rotating, relative to the ...

A billion years ago, days lasted 19 hours: the balance between the oceans, the atmosphere, and the Moon slowed down the Earth ...

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, ...

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 ...

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 ...

When Earth rotates as normal, the centripetal acceleration of the ground under your feet at the equator has the net effect of reducing the force of gravity on you, so you weigh about 0.3 per cent less ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet. The results of the research, ...
