When studying and formulating Albert Einstein's theory of general relativity, various mathematical structures and techniques are utilized. The main tools...

In general relativity, a geodesic generalizes the notion of a "straight line" to curved spacetime. Importantly, the world line of a particle free from...

General relativity does not offer a single definition of the term mass, but offers several different definitions that are applicable under different circumstances...

In general relativity, the metric tensor (in this context often abbreviated to simply the metric) is the fundamental object of study. The metric captures...

In general relativity, a congruence (more properly, a congruence of curves) is the set of integral curves of a (nowhere vanishing) vector field in a four-dimensional...

The two-body problem in general relativity (or relativistic two-body problem) is the determination of the motion and gravitational field of two bodies...

The mathematics of general relativity is complicated. In Newton's theories of motion, an object's length and the rate at which time passes remain constant...
