A simple formula that allows to calculate the curvature of the trajectory in the Minkowsky space-time of a point located at a fixed distance from a point mass

Fernando Salmon Iza

A formula that allows calculating the curvature of the trajectory in the Minkowski space-time (scalar curvature) of a point in the case of a gravitational field caused by a point mass, through the values of mass and spatial distance.
