Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under ...

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all.

Time for a physics lesson. We only feel gravity’s effect on us when we fall but gravity is always working on us- pulling us down at a force equal to our mass times a constant of 32 feet per second ...

A multi-decade analysis of a distant pulsar is affirming the longstanding notion that the gravitational constant—one of four fundamental forces of nature—is the same everywhere in the universe.

As far as physicists have been able to determine, nature speaks two mutually unintelligible languages: one for gravity and one for everything else. Curves in the fabric of space-time tell planets and ...

The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the ...

A magazine news story on the unification of physics usually begins by saying that Einstein’s general theory of relativity and quantum theory are irreconcilable. The one handles the force of gravity, ...
