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

Explore the complex challenges of quantum gravity in this video, examining the evolution of gravity models and the necessity ...

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

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, ...

Physicists have taken a new approach to whether all black holes conform to Einstein’s theory of general relativity or if ...

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 ...

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 ...

Photos and videos of astronauts on the ISS show them floating around, but saying there's zero gravity isn't fully accurate.

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 ...
