In 2023, scientists detected the gravitational waves from a black hole collision that seemed impossible. New research finally ...

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 ...

"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...

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

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 ...

String theory unifies all the forces of nature. Forces that seem very different, such as gravity and electricity, are deeply ...

Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...

A new theory suggests that time might not be a fundamental aspect of our universe but rather an illusion created by quantum entanglement. Quantum entanglement occurs when particles become ...

Let's rewind the clock back…oh, I don't know, let's say a hundred years. It was 1917, and Einstein had just developed his ...

Teaching relativity to a dog may sound like a hopeless mental exercise, but physics professor Chad Orzel says it actually makes the job of teaching relativity to humans easier. "It makes the whole ...
