Looking to extend his relativistic theory of gravity, Einstein specifies the tensor and field equations defining the spacetime curvature of a new Unified Field Theory in the 1940s. According to ...

A set of Albert Einstein's equations have sold for a staggering £604,800 - almost eight times their estimate. The physicist jotted down a diagram of a gravitational lens and over 30 complex ...

Rather, specific solutions exist for specific values, or specific sets of values, of the equations' parameters. Einstein’s field equations are like this. Spelled out in full, they represent a ...

Einstein's field equations; The energy conditions; Relativistic cosmology and the expanding Universe; (Special topics: Schwarzschild solution and black holes; Penrose-Carter diagrams; Quantum gravity) ...

This dimple in space-time is the result of what we call a gravity well, and it was first described over 100 years ago by ...

“We proved that the Einstein field equation from general relativity is actually a relativistic quantum mechanical equation,” the researchers note in their study. In simple words, this new ...

The Einstein field equations are a system of second order, non-linear, coupled differential equations in 4 variables. As you can imagine, solving such a system is not easy. If the system possesses a ...

The field equations then give the correct dynamics for the electromagnetic field. When Albert Einstein formulated his theory of gravity, he used mathematics known as pseudo-Riemannian differential ...

While still employing the metric of curved spacetime that Einstein used in his field equations, the researchers argue the presence of dark matter and dark energy -- which scientists believe ...

In 2001, Pawel Mazur and Emil Mottola proposed a different solution to Einstein's field equations that led to objects that they called gravitational condensate stars, or gravastars. Contrary to ...
