Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under ...

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 ...

Gravity, in the literal sense, keeps everyone (and everything) on Earth grounded. It acts as the anchor that prevents objects ...

Add Yahoo as a preferred source to see more of our stories on Google. A new way of explaining gravity could bring us a step closer to resolving the heretofore irresolvable differences it has with ...

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists ...

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 ...

Scientists aim to build the first graviton detector to explore gravity's quantum nature, despite significant challenges.

Bottom line: For decades, physicists have been trying to solve one of the greatest mysteries in science: how gravity operates at the smallest scales governed by quantum mechanics. While we have ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...
