The "Black Holes," as infinitely deep pits associated with a monstrous physical mass, have always been Sci-fi Type Fantasy. However, the data that generated this fantasy makes sense if one realizes that it refers to a region about the Center of Mass of whatever is being examined.The Cemter of Mass of any object is the point in the interior of an object at which there is a summation of all of the masses involved in the object which is equal in magnitude to the sum of all of the masses and opposite in sign as it is the balancer of all those masses. In the case of things such as Galaxies, where the object is somewhat diffuse and rather non-homogeneous, this huge "virtual" or "phantom" mass which has reality-- but is not a "PHYSICAL MASS composed of protons and electrons--will be in motion, changing position continuously, hence sweeping through a volume.....a This continuous motion can be expected to cause a commotion within the "matter" units within that volume such as to do an excellent job of disrupting electromagnetic transmission throught it..... This volume would be a "Black Hole." There is nothing wrong with the astronomers' data. They simply need to be a bit less fanciful in thier interpretation. One may note that they would never consider the foci of ellipsese as both being evidence of a concentration of MASS in the form of "proton-electron aggregates," so it is somewhat difficult to understand why they consider that "Black Holes," as foci of almost circular orbits, as evidence of such aggregates.... (Too bad that astronomers--and scientists in general--or not aware of the implications of the Oscillators-in-a-Substance Model which furnishes a clear understanding of a "One Force of Nature," with the concurrent definitions of Mass as a requisite for existence, and a true formulation of Gravity as a Compression rather than an "Attractive Fictional Force.")
