If you haven’t accomplished as much this summer as you had hoped to, you can blame forces far beyond your control: a few of these dog days, by one measure, are among the shortest you’ve ever lived ...

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 ...

Astronaut Shubhanshu Shukla has used a water blob to explain Earth's shape. Discover the physics of surface tension, rotation, and inertia in this space and physics explainer.

You're unlikely to miss the 1.25 milliseconds that will make Aug. 5 one of the shortest days ever. Earth's rotation is randomly speeding up, and nobody is quite sure why. These speedups, which have ...
