A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed ...

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 ...

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 ...

Measuring the strength of gravity is extraordinarily difficult, and different experiments have always disagreed – but a new ...

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 ...
