Transmitted by a yet-undetected particle that has zero rest mass, this inverse-square force of infinite range is modeled by the equation F equals G times m sub one times m sub two divided by r squared, where G is a constant measuring 6.67 x 10-11 Newton meters squared per kilogram squared.
Evidence for waves produced by this force has been gathered by observing orbits of close binary pulsars, and Arthur Eddington was the first to observe the bending of light by this phenomenon, called its namesake "lensing".

For 10 points, name this weakest of the four fundamental forces that Isaac Newton supposedly experienced when watching an apple fall.
