Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

Scientists in Greece have laid out a mathematical framework to help explain a so-far-unsolved gap in our understanding of how ...

Einstein’s general theory of relativity is a tool kit for solving problems involving gravity that connects mass and energy with deformations in spacetime. In turn, those spacetime deformations ...

Zero gravity, often depicted in science fiction and space documentaries, is a fascinating concept that sparks curiosity and wonder. Commonly misunderstood, zero gravity is not the absence of gravity ...

About a century ago, Albert Einstein amazed the world with his groundbreaking theory of relativity, and ever since he shared this profound understanding of gravity and spacetime, physicists everywhere ...

The first use of a novel method of analyzing Mars' gravitational force supports the idea that the planet once had an extensive northern ocean. In doing so, the method defines the scope of what ...

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 ...

(via PBS Space Time) 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 Einstein guy. Let’s see if we’ve finally ...

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 ...

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 ...
