Einstein’s General Theory Of Relativity Einstein’s General Theory of Relativity fundamentally redefines our understanding of gravity. It proposes that gravity is not a force as Newton thought, but rather a curvature in the fabric of spacetime caused by mass and energy. According to this theory, objects with mass warp the fabric of spacetime around them, and the larger the mass, the greater the curvature. Other objects moving through this curved spacetime will then follow paths dictated by this c
