The biggest open problem in the foundations of physics is that Einstein’s theory of gravity, General Relativity, does not ...

Three physicists have proposed a modification to Einstein’s general relativity that, if confirmed, could eliminate the singularity at the origin of the universe. By adding higher-curvature terms to ...

The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many ...

Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as singularities, i.e., points where the laws of physics break down. Identifying how ...

A RATHER glib distinction is often made between the two pillars of modern physics. Quantum mechanics is the physics of the very small, while general relativity is the physics of the very large. That’s ...

Cormac O’Raifeartaigh reviews The Perfect Theory: a Century of Geniuses and the Battle Over General Relativity by Pedro G Ferreira Fighting it out: an artist's impression of two black holes circling ...

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 ...

Pedro Ferreira looks back at how Einstein himself and a panoply of other physicists have framed the theory. Until very recently, relativists were few and often self-taught. General relativity still ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.
