Astrophysicists believe the only viable explanation for black holes is that there has to be a super massive, highly condensed piece of matter hidden in space.
This is not the only explanation, and neither is it the best explanation. The best explanation is that at the centers of galaxies space is unraveling. Space has structure, which is quantifiable, as I have shown in Secrets of the Aether. When space becomes too dense, it just unravels, and it unravels any matter that is within it. The unraveled matter converts from visible matter to dark matter, and radiates outward from the center of the galaxy as neutrinos.
Think of a large bathtub with a drain. As the water goes down the drain, all the other water in the tub migrates toward the drain. If there is something floating in the water, it may get close to the vortex of the drain, and be shot back out before actually heading straight into the vortex at a later time. This gives the appearance of being gravitationally attracted toward the vortex. You can imagine the vortex of a bathtub as having imaginary mass and design a whole set of equations to explain the action of the vortex in terms of Newton's gravitational laws. But this would be nothing more than an imaginary exercise, even though the math will work.
There are no super massive black bodies in the centers of galaxies. There is a drain of space, and every star is migrating toward the drain, which explains the inward spiral nature of galaxies and the observed behavior of stars "orbiting" the center.
