How Gravity Works at Microscopic Scales How Gravity Works at Microscopic Scales The Greatest Unsolved Problem of 20th-Century Theoretical Physics Is the Construction of a Quantum Theory of Gravity. saac Newton understood gravity in a rather mechanical way. (1) Objects with mass simply attract each other. The more mass they have, the stronger the attraction. (2) The force weakens as the separation between bodies increases. (This, by the way, explains why distant stars do not produce a significant pull on us on Earth -- they are too far away.) (3) Gravity is a very weak force. Hence, only very massive objects such as the Earth and the Sun can produce a sizeable gravity.
