General Relativity and Cosmology

General relativity is the theory of gravitation which provides a complete description of gravity as a geometric property of space and time. The understanding of how matter and radiation warps the geometry of space and time is governed by the Einstein field equations. This theory departs significantly from classical physics especially in relation to the geometry of space, the passage of time, the propagation of light and the motion of bodies in free fall. This is evident in its treatment of ...
