Because the Earth is doing the work of increasing the Moon's momentum, the Earth's rotation slows down in turn, as its ...

Tides come from a difference in gravity across an object. The force of gravity exerted by the Moon is about 4% stronger on the side of Earth that faces toward the Moon, compared to the opposite side ...

In my most recent article for Scientific American, I may have lied to you. In my defense, I didn’t so much lie as maybe oversimplify a tiny bit. I wrote that because of the effects of the tidal force ...

A study published in Nature Geoscience suggests that the gradual slowing of Earth’s rotation over billions of years may have played a key role in one of the most profound shifts in the planet’s ...
