The ( 1 − − 2 G M / ( c 2 r ) ) coefficient in front of ( c Δ Δ t ) 2 describes the curvature of time in Newtonian gravitation, and this curvature completely accounts for all Newtonian gravitational effects. As expected, this correction factor is directly proportional to G and M , and because of the r in the denominator, the correction factor increases as one approaches the gravitating body, meaning that time is curved.
