What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred ...

Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

In 1915, Einstein proposed that gravity actually distorts the fabric of space. His calculations perfectly explained certain astronomical observations that Newtonian physics could not account for – ...

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 ...

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 ...

Sometimes the biggest puzzle in physics seems like the worst relationship in the universe. Quantum mechanics and general relativity are the two best theories in physics, but they have never been able ...

When two massive black holes slammed into each other earlier this year, astronomers were able to observe it in the clearest ...

The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

A DECADE after scientists initially detected gravitational waves from colliding black holes, advanced technology and fortuitous timing have enabled researchers to capture the most detailed evidence ...
