SUMMARY
Length contraction does occur in gravitational fields, as established by general relativity. The equation governing gravitational length contraction is given by ds = (1 - (2GM/c²r))^(-1/2) dr, where G represents the gravitational constant, M is mass, c is the speed of light, and r is the radial coordinate. The SI unit for mass is kilograms, while weight is measured in Newtons. This discussion clarifies the relationship between mass and gravitational effects on length.
