Nobody really understands gravity. We know what it does. We have equations for it, and we're constantly correcting GPS satellites because of it. But ask a physicist what that pull actually is, and ...

Is gravity just an emergent effect of entropy? Gravity might not be a more fundamental than the force of a stretched elastic band. Maybe gravity is just an entropic byproduct—an emergent effect of the ...

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 ...

EVERYWHERE YOU LOOK, you can see gravity’s fingerprint. It’s in the path the moon takes around Earth each night and the humbling thump when you wipe out on an icy patch of sidewalk. The force of ...
