  Micro black hole - Wikipedia, the free encyclopedia
Black holes are thought to evaporate over time due to Hawking radiation, and the less the mass, the faster one evaporates.
The maximum mass of a micro fl hole in which quantum mechanical effects play a dominant role is the Planck mass.

 Black hole - Biocrawler   (Site not responding. Last check: 2007-11-02)
Black holes require the general relativistic concept of a curved spacetime: their most striking properties rely on a distortion of the geometry of the space surrounding them.
Supermassive fl holes containing millions to billions of solar masses could also form wherever a large number of stars are packed in a relatively small region of space, or by large amounts of mass falling into a "seed" fl hole, or by repeated fusion of smaller fl holes.
Though the details are still not clear, it seems that the growth of the fl hole is intimately related to the growth of the spheroidal component — an elliptical galaxy, or the bulge of a spiral galaxy — in which it lives.

 Intermediate-mass black hole - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-11-02)
An Intermediate-mass fl hole (IMBH) is a fl hole whose mass is significantly more than stellar fl holes (a few tens of the mass of the Sun) yet far less than supermassive fl holes (a few millions of the mass of the Sun).
On the one hand, they are too massive to be formed by the collapse of a single star, which is how the stellar fl holes are thought to form.
The first, is the merging of stellar mass fl holes and other compact objects by means of gravitational radiation.

 Black Holes
Stellar-mass fl holes may be involved in gamma ray bursts (GRBs), although observations of GRBs in association with supernovae or other objects that are not fl holes have reduced the possibility of a link.
The current picture is that all galaxies may have a supermassive fl hole in their center, and that this fl hole swallows gas and dust in the middle of the galaxies generating huge amounts of radiation - until all the nearby mass has been swallowed and the process shuts off.
Though the details are still not clear, it seems that the growth of the fl hole is intimately related to the growth of the spheroidal component - an elliptical galaxy, or the bulge of a spiral galaxy - in which it lives.

The existence of fl holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei.

The Schwarzschild radius is proportional to the mass, with a proportional constant involving the gravitational constant and the speed of light.
The larger the mass of a galaxy, the larger is the mass of the supermassive fl hole in its center.
Such fl holes might possibly be formed in an early stage of the evolution of the universe, just after the Big Bang, when densities were extremely high.

 Time Travel Portal :: View topic - Black Holes, Singularities & Wormholes
A fl hole forms when an object collapses to a small size (perhaps to a singularity) and the escape velocity in its neighborhood is so great that light cannot escape.
The usual idealised "static" fl hole is stationary, unaccelerated, at an arbitarily-large distance from the observer, is perfectly spherical, and has a point-singularity at its centre.
The idea of being able to treat a non-rotating fl hole as either a point-singularity or a hollow infinitely-thin film is a consequence of the result that the actual mass-distribution is a "null" property for a fl hole, as long as it is spherically symmetrical.

In general relativity, there is no minimum mass for a fl hole and there is no gravitational time dilation limit, other than (the unrealistic) zero seconds per second.
Very small mass fl holes would look like elementary particles because they would be completely defined by their mass charge and spin.
Black hole theory predicts that a fl hole with charge and spin will have magnetic moment equal to charge times angular momentum divided by mass.

 black hole in The AnswerBank: Science
As far as I am aware, fl holes are only a theory and no one has actually proved their existence yet.
Black holes are a lot more than just a theory, the evidence is now pretty overwhelming in fact here's a picture:
The main reason I cannot see an atomic nucleus being a fl hole (certainly among the elements we know about) is that the increasing density observed in collapsed stars comes about because the space between the nuclei and electrons is reduced by the effect of gravity.

 Black Hole on earth? - Forums powered by UBBThreads™   (Site not responding. Last check: 2007-11-02)
A fl hole of the size you could create by human means is not going to devour the Earth.
In fact if a slightly larger hole could be built, which did not evaporate immediately, we could use the Hawking radiation as a power source; to compensate for the mass the fl hole would lose by Hawking radiation, just throw more mass in to the hole at a steady rate.
This Brookhaven 'fl hole' experiment, is in fact probably being duplicated with cosmic rays and such all over the universe, to apparently no ill effect.

If a MBH accrete a quark, the whole nucleon can be expected to be caught because otherwise the fl hole would have acquired a charge which is not complete.
Around a fl hole there is not an electronic cloud and there is no degenerate pressure to counterbalance the pressure of all the Earth matter.
Black holes in Astronomy have an important mass, so the evaporation is very tiny and cannot be seen.

 Dialogos of Eide: Cosmic Variance's Very Own: Strangelets in 10 or 11
Son and two colleagues used a string theory method called the gauge/gravity duality to determine that a fl hole in 10 dimensions -- or the holographic image of a fl hole, a quark-gluon plasma, in three spatial dimensions -- behaves as if it has a viscosity near zero, the lowest yet measured.
The fl hole electron core(gravitationally trapped electromagnetic energy) evidence comes from a number of sources and is summarised in my articles in Electronics World, Aug 02 and Apr 03.
The fl holes of the spacetime fabric are the virtual fermions, etc., in the vacuum, which are different from the real electron, because the real electron is surrounded by a polarised layer of vacuum charges and Higgs field, which gives the mass.

 Cubic Lightyear
QUESTION(s): What if a micro fl hole the size of a grain of sand were to encounter another object such as Earth, where the mass ratio of the fl hole were but one millionth (5.976^18) that of Earth.
Obviously that micro fl hole encounter would create a terrifically big bang but not apprecibly alter Earth (in other words you and I would be quite dead but Earth would likely survive).
Certainly that micro fl hole would be assemilated into Earth (which ever object is bigger [in terms of mass] would likely prevail unless this micro fl hole were to be traveling at merely 0.1% light speed) but then, what if the substance of the micro fl hole were unlike any elements of Earth, then what?

Once created, the micro-fl hole decays quickly and emits over a dozen different kinds of particles such as electrons, neutrinos and photons, which are easy to detect.
Using the predicted decay properties of the fl hole into neutrinos, Hewett, Lillie and Rizzo solved complex equations to determine if our universe has 10, 11, or more dimensions — perhaps too many dimensions to be explained by critical string theory.
More technically, the analysis applies to models of extra dimensions where micro-fl holes can be formed with a size smaller than the curvature of the additional dimensions and where the fundamental particles which make up our universe do not reside in the extra dimensions.

 The Potential for Danger in Particle Collider Experiments
When a neutron star begins to collapse in a fl hole (implosion), at the beginning the fl hole is only a micro fl hole as we see in [Ref. 7 Page 443].
We must remember that in the surrounding of the MBH the "strong force" is broken and this could mean that the same kind of pressure process than in neutron star could work there (in a slow mode compared with a neutron star of course).
Our calculus indicates as a first approximation with a MBH of 0.02 g at rest at the center of earth that the value for accretion of matter could be in the range of 1 g/sec to 5 g/sec.

 Citebase - Generalized Uncertainty Principle in Quantum Gravity from Micro-Black Hole Gedanken Experiment   (Site not responding. Last check: 2007-11-02)
In the current standard viewpoint small fl holes are believed to emit radiation as fl bodies at the Hawking temperature, at least until they reach Planck size, after which their fate is open to conjecture.
We argue that, when the gravity effect is included, the generalized uncertainty principle (GUP) may prevent fl holes from total evaporation in a similar way that the standard uncertainty principle prevents the hydrogen atom from total collapse.
We show that the Hawking temperature and the entropy of fl holes are subject to corrections from two sources: the generalized uncertainty principle and thermal fluctuations.

 DVD Talk > Reviews > Cybuster: Tokyo 2040 #4: Micro Black Hole Cannon
The latest anime release with this type of thing in mind is Cybuster: Tokyo 2040 #4: Micro Black Hole Cannon, following the continuing adventures of a group of heroes attempting to reclaim their lives in the face of a coup at the place they used to work.
Now in the fourth set of episodes, Cybuster: Tokyo 2040 #4: Micro Black Hole Cannon, the show sets the stage for the coming battle between the forces of good and the forces of evil, with a few false starts on the part of some of Ken's old co-workers.
Final Thoughts: Cybuster: Tokyo 2040 #4: Micro Black Hole Cannon was a show I really, truly, wanted to like more than I did but it was so LCD (lowest common denominator) as to make me predict virtually every aspect of the episodes by their name alone (before ever popping the DVD inside the player).

 Re: Can anyone sum up the current state of the micro-black-hole discussion?
If you were worried about fl holes swallowing the Earth, you would be more concerned with nature.
I mean, in the few short years we've been able to observe them, we've seen cosmic protons with a Joule of energy...about 10 million times the energy we can create in the lab (10^12 eV is a TeV, which is close to what we currently can make at a huge accelerator).

Researchers at Brookhaven National Laboratory in Upton, New York have created a very short-lived, very tiny fl hole, or at least, a fireball that behaved quite a lot like one for a millionth of a billionth of a billionth of a second.
According to Metro, a Daily Mail sister publication, some particles were then absorbed by the plasma in the same way that particles are absorbed by fl holes.
While the research team at RHIC has described the work as groundbreaking, other scientists are unsure about that possible applications for the work.
