A researcher throws cold water on a recent effort that purported to eliminate black holes' greatest and most enduring mystery ...

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 ...

“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 ...

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 ...

Einstein elaborated this dramatic insight in several equations, referred to as his “field equations,” that form the core of his theory of general relativity. That theory has been vindicated by every ...

By adapting mathematical techniques used in particle physics, researchers in Germany have developed an approach that could boost our understanding of the gravitational waves that are emitted when ...

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 ...
