Expert Answer:

Though some scientists theorize that gravity is caused by particles called gravitons, most agree that gravity is a product of mass. Everything with mass, from a dust mote to a star, exerts a gravitational pull. The force of the pull, however, increases with mass and proximity to the object. So a small object can only attract another small object that's nearby, but a large object, like a planet or a star, can pull in objects from across a vast distance. Einstein revised this theory further, saying that when a large mass causes a distortion in space, objects that come within that distortion will be attracted to the mass.
