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 ...

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 ...

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 ...

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 ...

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 ...
