The astrophysics literature tries to make a case for the existence of a supermassive black hole at the center of Milky Way, in the location of the radio source Sagittarius A*. We think that, with arguments of the very same nature, the evidence points quite to the contrary. While the observational data on the orbits of the starry objects around Sagittarius A*, being of a projective character, are entirely reliable, their physical explanation uses quite a particular type of Newtonian forces, namely those with magnitude depending exclusively on the distance between bodies. To begin with, this limitation assumes a priori that the bodies connected by such forces are special material points, viz. space positions endowed with mass. At space scales such as that of the galactic center region in discussion, this assumption is not realistic, and therefore, implicitly, such particular forces are themselves not quite realistic. Still using Newtonian forces in argument, strongly suggested by observational data as a matter of fact, one should allow, on such an occasion, their full generality. This means that we only need to assume that they are central forces with no other further constraints. Within the framework of the Newtonian theory of forces this freedom has important theoretical consequences discussed in the present work. Among these the chief one, from astrophysical point of view, is that the presence of a supermassive black hole in the center of Milky Way might not be a sustainable assumption. An alternative is presented.
