Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under very different disguises. For centuries we have treated gravity as the ...

Gravity has become an unlikely viral villain, blamed for an imagined global blackout in which the planet briefly lets go of everything that is not nailed down. At the same time, some of the most ...

A fresh look at gravity challenges long-held assumptions about one of nature’s most familiar yet puzzling forces. In a new study, two researchers argue that gravitational attraction is not a basic ...

Gravity feels steady. You drop a set of keys, and they fall the same way every time. That reliability makes it tempting to picture Earth’s pull as uniform. It is not. After accounting for Earth’s ...

We all know gravity as the invisible force that keeps us grounded. But what if it's not a force at all? What if it's a function? One physicist believes gravity might actually be one of the strongest ...

A new argument explores how the growth of disorder could cause massive objects to move toward one another. Physicists are both interested and skeptical. Isaac Newton was never entirely happy with his ...

We have long taken it for granted that gravity is one of the basic forces of nature–one of the invisible threads that keeps the universe stitched together. But suppose that this is not true. Suppose ...
