How does Einstein's theory of gravitation, compared with Newton's, explain the nature of gravity in the universe?

Einstein's theory of gravitation, known as General Relativity, provides a more comprehensive explanation of gravity compared to Newton's theory. While Newton described gravity as a force acting between objects with mass, Einstein's theory views gravity as the curvature of spacetime caused by mass and energy. This means that objects with mass distort the fabric of spacetime, causing other objects to move along curved paths. General Relativity has been able to accurately predict phenomena such as the bending of light around massive objects and the existence of black holes, expanding our understanding of gravity in the universe.
