Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

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 ...

There are some things in life that just sort of happen. Desks get covered in dust and scraps of paper. Clothes get dirty and the laundry basket fills up. Weeds slowly creep across an untended ...

The holy grail of theoretical physics is to come up with a quantum theory of gravity. But after a century of trying we really have no idea how close we are, or it it's even possible. But we shouldn't ...

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 ...

A new argument explores how the growth of disorder could cause massive objects to move toward one another. Physicists are both interested and skeptical. Isaac Newton was never entirely happy with his ...
