For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

Leonardo da Vinci's centuries-old sketches reveal he may have understood key aspects of gravity long before Galileo, Newton and Einstein. A recent study from the California Institute of Technology ...

Isaac Newton lounging beneath an apple tree, suddenly getting bonked on the head by falling fruit, and boom—gravity is ...

Leonardo da Vinci’s understanding of gravity, while not completely accurate, was “centuries ahead of his time”, according to a new study that reasessed sketches in the Italian polymath’s old notebooks ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

We probably think we know gravity pretty well. After all, we have more conscious experience with this fundamental force than with any of the others (electromagnetism and the weak and strong nuclear ...

To understand gravity, Einstein had to rethink space and time as a single connected fabric. He showed that mass bends this fabric, guiding how everything moves. NOVA is available to stream on pbs.org ...

Early on in science classes all over the world, students drop diverse things to learn how gravity works and how outside forces might affect the rate of fall. But the science of falling goes well ...

We learn more about Modified Newtonian Dynamics aka MOND. What if there is no such thing as dark matter? What if our understanding of gravity is just wrong? New work is taking another shot at that ...
