OK, so its not quite as sensational as it sounds— UK scientists have been trying to simulate conditions near the event horizons that shroud black holes, and they've cleverly simulated a horizon using pulses of light in a special optical fiber. So, no disastrous gravity well was made and the world didn't suddenly end with a horrible crunch. But they did create an analog of a black hole that helped them understand some of the weird and whacky physics that goes on near real ones. The team actually made "completely harmless" black hole and white hole horizons in pairs, at a rate of 80 million a second, by piling up and stretching out ultrashort light pulses in the modified optical fiber. They even detected blue-shifting effects at the white hole horizons, which is predicted by theory. 
Tell me, has any scientist actualy tried to create or simulate a black hole on Earth, to try to study them, or harness power? And if so, how was this done. If noone ever tried, What are the theories of making one? How would it be possible to create one? EDIT: I no longer call bullshit on this idea, due to the correction in the replies, however, please feel free to discuss Post edited at 12:47 pm on April 16, 2008 by Crazy snake

Ok, I dont believe this, because #1: The gravitational pull of a black hole, would suck everything near it into it, and couldnt be controled/stopped. #2: Do humans even have the technology to start doing this stuff yet? I mean, this is ADVANCED stuff So I think its bull shit. Tell me, has any scientist actualy tried to create or simulate a black hole on Earth, to try to study them, or harness power? And if so, how was this done. If noone ever tried, What are the theories of making one? How would it be possible to create one? I dont believe it would be 
you obviously are not keen on the physics of black holes huh? the energy needed to keep a black hole "alive" is astronomical. Most likely, it was done in a vacuum, with limited energy being added. The black holes were not visible --which is why they made 80 million PER SECOND-- nor did they last any longer than a millionth of a second in duration. And you are asking how its done? I suggest you start working on a Ph.D. in Particle physics and quantum mechanics if you are really interested.

Yeah, you clearly don't have a good grasp of Physics. Black holes are very complicated, and just because you don't understand them doesn't mean you can call bullshit on the idea. These physicists are a billion times smarter than yourself. It is important to note that these black holes are micro black holes and aren't the same as gravitational black holes (that 'pull' everything into it).
They act like black holes because of the correspondence between the theory of the strong nuclear force, which has nothing to do with gravity, and the quantum theory of gravity. They are similar because both are described by string theory. So the formation and disintegration of a fireball in quark gluon plasma can be interpreted in black hole language. The fireball at the Relativistic Heavy Ion Collider [RHIC] is a phenomenon which is closely analogous to a black hole, and many of its physical properties can be correctly predicted using this analogy. The fireball, however, is not a gravitational object. It is presently unknown whether the much more energetic Large Hadron Collider [LHC] would be capable of producing the speculative large extra dimension micro black hole, as many theorists have suggested. 
You also have to add the fact that so many were being created, because the micro black hole evaporates before it could propagate further, due to Hawking radiation.

Whoop-de-doo. I am in fact, about to sit my last Physics A-Level exam. I am dissing you, because you called bullshit on this idea, purely because you couldn't understand it. You can't invalidate an idea because you don't get it, that's stupid. In future, don't be so dismissive about things you can't comprehend. It is a confusing matter, which is why many people cannot understand it or how it works. A micro black hole is created not by the end of the life of a star, but from a primordial black hole, which is caused by the density of matter during the initial stages of the Universe's expansion.
Under these conditions, simple fluctuations in the density of matter may have resulted in local regions dense enough to create black holes. Although most regions of high density would be quickly dispersed by the expansion of the universe, a primordial black hole would be stable, persisting to the present. Under some theories, re-creation of these early conditions in particle accelerators such as the Large Hadron Collider might possibly allow for creation of the smallest versions of such micro black holes. 
I'm not sure where you got this idea of light causing a black hole from, to be honest.

Actually I think the OP wasn't calling it "bullshit" because he couldn't understand it, but rather, because the actual quotation does not sound plausible

Dont pretend you do, either.

Finaly! An intellectual who understood what I said! Thank you, and do you personaly think that that quotation is plausible?

I don't know what you're getting at, but I wasn't pretending anything. Unlike most users on here, when I open my mouth I know what I'm talking about. Either way, the basis of the OP calling it bullshit was still idiotic, whilst it may not sound plausible, he still had no grasp of it (not saying i am either), so he dismissed the idea. My original answer still applies.
