Planck, Haug, escape velocity, golden ratio, black hole
Escape velocity from the E.G. Haug has been checked. It is compared with orbital velocity formula for an ideal circular path. The formulas are simplified so that we have only one variable that contains the Planck values and the mass of the central body. In the case of an arbitrary star, the values of these velocities are determined during its compression to the black hole. Unlike the standard and relativistic formulas that are approximations for a weak gravitational field, Haug's formula is exact for a weak and strong gravitational field. The relationships between formulas showed the importance of the golden ratio near the black hole.
