General Relativity is Einstein's geometric description of gravity which brings together special relativity and gravity in one consistent set of equations.

#### Explanation:

General Relativity is Einstein's geometric description of gravity which describes how the curvature of space and time (or spacetime) relates to the energy and momentum of the mass and radiation in it. It brings together special relativity and gravity in one consistent set of equations.

In astronomy, it allows us to predict and understand many phenomenon, like black holes, the expanding universe, gravitational lensing, gravity waves and so on.
