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 ...

Explore the complex challenges of quantum gravity in this video, examining the evolution of gravity models and the necessity of quantum gravity. Delve into key topics such as the 3D Bronstein cube, ...

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 ...

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as ...

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 ...

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 ...

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 ...

(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 ...
