A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept ...

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

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

THIS monograph collects, in 87 pages, those deductions of the results of relativity theory that find most frequent application in physics. The applications of special relativity to kinematics, ...

Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put 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 ...

Gravitational physics has become a truly experimental science as tests of the special and general theories of relativity reach new levels of precision Right on time When I was a first-term graduate ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their ...

New research from UBC Okanagan mathematically demonstrates that the universe cannot be simulated. Using Gödel’s ...

In a new, detailed breakdown of current theory, a team of physicists led by Mir Faizal of the University of British Columbia ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you were a physicist in the early 20th century, there would have ...

One of the biggest problems with physics is that, apart from a few mysteries we cannot adequately explain, the things we do understand work extremely well. Too well, in fact, for our comfort. Almost ...
