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 ...

The Event Horizon Telescope only recently gave us the first images of the environment immediately surrounding a black hole.

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 ...

PITTSBURGH (KDKA) -- We have discussed gravity in a couple different experiments. This time, I am going to show you something that may seem almost impossible to do. Then we will discuss how it works, ...

Learn what a black hole is, how it forms, and how astronomers detect it. Understand the science behind black holes and their ...

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 ...

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 ...

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 ...

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 ...
