A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of physics.

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 ...

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 ...

How does gravity work? Gravity applies an effective force of mutual attraction to things with inertial mass, including physical matter and photons. The force of gravity is transmitted through ...
