For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

As far as we know, our physical world is governed by four fundamental forces: electromagnetism, weak and strong nuclear forces, and gravity. Apart from playing with bar magnets or marveling at the ...

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

EVERYWHERE YOU LOOK, you can see gravity’s fingerprint. It’s in the path the moon takes around Earth each night and the humbling thump when you wipe out on an icy patch of sidewalk. The force of ...

Emergent gravity is a bold idea. It claims that the force of gravity is a mere illusion, more akin to friction or heat—a property that emerges from some deeper physical interaction. This emergent ...

Scientists could be wrong about dark energy. But they’re right about gravity, a new study suggests. Dark energy, the mysterious phenomenon that causes the expansion of the cosmos to accelerate, is ...

WASHINGTON, May 14 (Reuters) - An exhaustive examination of lunar gravity using data obtained by two NASA robotic spacecraft is offering new clues about why the two sides of the moon - the one ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

Gravity is the reason things with mass or energy are attracted to each other. It is why apples fall toward the ground and planets orbit stars. Magnets attract some types of metals, but they can also ...

In the April 1981 issue of Popular Science, we explored the many initiatives and techniques used in the exciting hunt for sensing gravity waves, then out of reach. By Bill Gourgey Published May 18, ...
