Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

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 ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

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 ...

The first image of a black hole, captured in 2019, has revealed more support for Albert Einstein's theory of general relativity. The new finding has suggested his theory is now 500 times harder to ...

In 1915, Albert Einstein put forth a new theory of gravity: General Relativity. Instead of every mass in the Universe instantly reaching across to every other mass and exerting an attractive force, ...

Astronomers have finally watched a black hole do something Albert Einstein only described on paper: twist the very fabric of ...

Albert Einstein's theory of general relativity has been proven right again — and this time, physicists have pinned down just how precise it is: Any deviations from his theory of general relativity are ...

Albert Einstein is unquestionably one of the greatest scientists to ever live. He’s responsible for likely the most well-known equation of all time, and decades after his death, his work is still a ...

Einstein's theory of general relativity is rather important when it's crucial to the modern understandings of the universe and technology like satellites. But does it hold up with something as vast as ...

Einstein's theory of relativity reveals that gravity is a bending of space. One of the predictions of the theory is that two closely orbiting astronomical bodies will lose energy by a phenomenon ...
