For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

Another theory held that the forces between two particles falls off exponentially in direct relationship to the distance between two particles and that the factor by which it drops is not dependent on ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than ...

Of the four fundamental forces, gravity is the one we’re most familiar with in our everyday lives, but perhaps surprisingly, it’s the weakest and hardest to measure here on Earth. Now, physicists in ...

Why does skydiving work and how do humans safely experience one of the most dramatic adventures in the sky? To better ...

Because of years of practice, the players who astonish us game after game make these micro-calculations at an unconscious level. In a fraction of a second, their eyes assess all the variables, and ...
