Normal galaxies seem to have masses of about 1011 times that of the sun. The unthinkable assumption suggests that every 108 years or so, these ordinary, unassuming galaxies become supermassive (about 1013 solar masses) for several million years. When the core of a galaxy becomes supermassive, its stars are tugged into tight new orbits. The subsequent switching off of the supermass allows the galaxy to expand outwards again. The author claims to have found just such expansion effects among the globular clusters in our own galaxy. His data are striking and quite convincing. The notorious "missing mass" problem of cosmology disappears with the cyclic supermass assumption because the time-averaged mass of each galaxy will be much higher than that observed in its normal enervated state. Doesn't this sudden temporary appearance of mass violate the laws of physics? No, says the author, physicists habitually assume a superfluid, superconducting vacuum state, which is the ultimate source of all mass-energy, when they develop their theories of fundamental particles. If particle physicists can (and must) evoke such magic, so can astronomers. (Clube, Victor; "Do We Need a Revolution in ...

... -3 , and AD 620-00. All objects previously proclaimed to be small black holes have instead turned out to be neutron stars. (Ref. 1) The case for massive black holes weighing in at millions of solar masses is not overwhelming either. These are supposed to lurk in the centers of galaxies. To find them, astronomers look for intensely bright spots in galaxies, around which swirl stars at speeds approaching the speed of light as they are sucked into the black hole's maw. Such fantastic celestial maelstroms do seem to exist, as evidenced by "something" in the giant elliptical galaxy M87. (Ref. 1) New claims for massive black holes are always being put forward. The spiral galaxy NGC 4328, for example, is thought to harbor a supermassive black hole weighing in at 40 million solar masses! (Ref. 3) However, claims for massive black holes are also being shot down all the time. Several have thought they had found a massive black hole at the center of our own galaxy. This no longer seems likely. (Ref. 4) Conclusion. Don't be too quick to accept such bizarre constructs as black holes, whether small or massive.
