{wiki=Einstein–Hilbert_action}
The Einstein-Hilbert action is a fundamental concept in the realm of theoretical physics, particularly in the fields of general relativity and the formulation of gravity as a geometric theory. It represents a way to describe the dynamics of spacetime and the gravitational field using the language of action principles, which are a cornerstone of classical field theory.
