Learn more about the images advanced telescopes could take of black holes and how they could back up Einstein’s general ...

BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called ...

Interstellar comet 3I/ATLAS, which originated outside our solar system, has reportedly confirmed one of Albert Einstein's ...

A black hole can feel like the most distant and unreal object you could ever think about, yet the way its darkness bends ...

Researchers are using black hole “shadow” images to test whether Einstein’s relativity remains unshakable. With next-generation telescopes, they hope to spot telltale signs of alternative physics ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

Black holes, regions of spacetime in which gravity is so strong that nothing can escape, are intriguing and extensively studied cosmological phenomena. Einstein's general theory of relativity predicts ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

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 search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...
