Just as a bowling ball set down on a large trampoline makes a depression in its surface, a large mass such as the sun will curve or depress the fabric of spacetime. The more mass an object has, the larger the warp or depression. Objects having less mass “fall into” the depression in spacetime caused by objects with larger mass, just as tennis balls at the edge of a trampoline will roll into the depression created by a bowling ball placed in its center. Thus, general relativity, and Einstein’s field equations expressing the theory mathematically, describe how curved space affects the movements
