Certainly! General relativity is an extension of special relativity that includes gravity. While special relativity deals with objects moving at high speeds in flat spacetime (i.e., without gravity), general relativity describes how objects move in the presence of gravity, which is caused by the curvature of spacetime.

Albert Einstein developed general relativity in 1915, about ten years after he introduced special relativity. The main idea of general relativity is that gravity is not a force between objects, as described by Newton's law of universal gravitation, but rather a curvature of spacetime caused by the presence of mass and energy. Objects move along the shortest paths (called geodesics) in this curved spacetime, which we perceive as the force of gravity.

General relativity reduces to special relativity in the absence of gravity or when dealing with objects moving at high speeds in a small region of spacetime where the curvature is negligible. In other words, special relativity can be seen as a special case of general relativity, where the effects of gravity are not considered.

General relativity has been confirmed by many experiments and observations, such as the bending of light by massive objects (gravitational lensing), the shift in the orbit of Mercury (perihelion precession), and the detection of gravitational waves. It is also the basis for our current understanding of black holes and the expansion of the universe.
