Black Holes: Classifications...


Mini Black Holes have never been detected though it has been postulated by the string theorists that such small black holes could have been formed in the aftermath of the Big Bang. The French are presently striving to create these potential disasters since "tiny black holes could offer a richer view of physics." The French scientists tell us not to worry; "that these black holes are not dangerous and do not threaten to swallow up our planet." Obviously if they are wrong we will all be to blame for the destruction of the earth. Dr. Stephen Hawking, University of Cambridge, addresses this issue in his February 4, 2005, speech on 'Black Holes and the Information Paradox' at this website.

2) Stellar Black Holes have a mass of about 5 to 100 Suns.  These black holes form at the very end of the life cycle of very massive stars.  It all starts with a gamma-ray burst; the most powerful type of explosion in all of the universe, followed by intense pulses of X-rays.  These dying stars will then explode up to four times in the very first minutes following the initial explosion. As the solar matter is falling into the black hole, it releases a great amount of energy and matter which gets blasted away from the black hole and flies out into the interstellar medium and nearly the speed of light. A bulging fireball dome of material condenses surrounding the black hole erupting in two narrow polar jets of gamma-rays and X-rays.  When these massive stars finally do collapse under their own gravitational forces all of their matter is crushed into the most basic of particles: a quark-gluon plasma.  The outer boundary of a black hole is called the event horizon.  An animation of how this process works is shown here.

3.) Mid-Mass Black Holes have a mass of between 500 to over 1,000 Suns.  The gravitational force of the these black hole pulls surrounding matter and stars into and beyond the event horizon, from which not even light waves can escape because the gravity is too strong. Since nothing can escape from a black hole, all of the energy and mass of the matter is captured inside of the black hole.  These black holes are like a giant vacuum cleaners in space, sucking in matter and compressing it into an extremely dense hot plasma.  Mid-mass black holes play a very critical role in the birth of young galaxies.

4.) Super-Massive Black Holes have a mass of a million to over a billion Suns.  These black holes are located in the centers of most galaxies, especially those with the classic center bulge, including our Milky Way Galaxy, which has a black hole mass of over 2.6 million Suns.  These massive black holes often have large accretion disks and gamma ray "jets" and frequently they power quasars.  They are one of the main fundamental forces in the development and ultimate shapes of their galaxies and thereby the distribution of the stars and dark matter in them.

5.) Deep-Core Black Holes have a mass of over 3 billion suns.  These black holes have so much mass that the fabric of space can no longer support them.  Once these black holes begin to sink deep toward the center of the universe, they begin stretching and pulling at the fabric of space behind them; and with that their accretion ring, the whole of their galaxy and the trailing dark matter.  These black holes, combined with the galaxies of matter gravitationally-locked behind them, eventually act as brakes on the expansion of the universe.  As more and more of these deep-core black holes are formed and disappear from sight, the universe slowly begins to contract.



Galaxy 'A' has been pulled lock-step by its deep-core black hole, spiraling downward toward the center of the universe.  The trailing dark matter quickly obscures the view of the retreating galaxy -- stretching and pulling the fabric of space as it recedes. 95% of the total mass/energy of Galaxy 'A' is contained within the trailing dark matter/dark energy thereby greatly increasing the rate of descent.

Galaxy 'B' which is being pulled by the stretching of the fabric of space, begins to accelerate towards Galaxy 'A'.

Galaxy 'C' appears to be accelerating away from Galaxy 'B' due to the effect of the stretching and pulling of the fabric of space caused by Galaxy 'A'. This 'observed' appearance of an expanding universe is being distorted by the gravitational effects of the deep-core black hole and its surrounding galaxy. It is quite probable that the Galaxy 'C' region could be expanding, static or even contracting -- in complete contradiction to what is being astronomically 'observed'.
