Earth's rotation is randomly speeding up, and nobody is quite sure why. These speedups, which have occurred several times over the last few years, haven't had any effect on daily life, but they also ...

As early as 2024, scientists from the US and China discovered that the Earth’s core had slowed down and even stopped moving in relation to the Earth’s crust. But until now, the general public—that’s ...

Climate change is causing the ice masses in Greenland and Antarctica to melt. Water from the polar regions is flowing into the world’s oceans –and especially into the equatorial region. “This means ...

In a world chasing cleaner energy, a group of physicists may have uncovered a surprising new way to make power: by tapping into the Earth's own rotation. That's right, researchers at Princeton ...
