The Einstein equations are fundamental to our understanding of general relativity, describing how ... study is crucial for understanding the long-term dynamics of cosmological models and the ...

The Einstein equations of general relativity are hyperbolic evolution equations. Here we are interested in understanding the long term dynamics of the equations near black hole solutions (stability), ...

Studying the equations of General Relativity and beyond, both analytically and with state-of-the-art simulations. Novel numerical and mathematical approaches can shed light on the structure and ...

“We proved that the Einstein field equation from general relativity is actually a relativistic ... charge of leptons ...

It took Einstein 10 years to make the theory work for gravity too, which is how general relativity gets its name. The theory is a series of equations defined by Einstein. These equations combine ...

Albert Einstein's general theory of relativity is one of the towering achievements of 20th-century physics. In our introduction to general relativity, we explain how this theory developed ...

General relativity describes gravitation in a geometrical framework generalizing special relativity and classical mechanics. This term includes theoretical studies of gravity, experimental studies ...

At the heart of this enigma is the question: how does the universe, if fundamentally quantum, adhere to classical laws like general ... equation by introducing nonlinear and stochastic terms ...

But because even a static universe would eventually collapse under its own gravity, he had to slip a fudge factor into the equations of general relativity—a cosmological constant. While gravity ...
