In recent years, UC Santa Barbara scientists showed that they could reproduce a basic superconductor using Einstein's general theory of relativity. Now, using the same theory, they have demonstrated that the Josephson junction ...

Some 13.8 billion years ago, the universe began with a rapid expansion we call the Big Bang. After this initial expansion, which lasted a fraction of a second, gravity started to slow the universe down. But the cosmos wouldn't ...

Einstein famously laboured hard to create the theory of general relativity, but it is less well known that he also helped to launch quantum mechanics, which he didn't much care for. These two views of the world are the very ...

(PhysOrg.com) -- In his discussion of accelerated motion on page 60 of The Meaning of Relativity, Albert Einstein made an approximation that allowed him to develop the theory of relativity further. Einstein apparently never ...

Small modeling errors may accumulate faster than previously expected when physicists combine multiple gravitational wave events (such as colliding black holes) to test Albert Einstein's theory of general relativity, suggest ...

(Phys.org) —Over the next five years, Mansi Kasliwal writes in an astrophysics perspective in the journal Science, researchers will begin setting up experiments designed to detect gravitational waves. Kasliwal, an astronomer ...
Researchers have, for the first time, identified the sufficient and necessary conditions that the low-energy limit of quantum gravity theories must satisfy to preserve the main features of the Unruh effect.
