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.

It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in ...

Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity ...

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 ...

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 ...

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing group of physicists is treating it as a possible glitch report from the fabric ...
