Man-Made Black Holes

[Max]

Did anyone read the article in Popular Science about scientists creating Black holes with a particle accelerator? Over 10,000 scientists from 50 different countries are building a new particle accelerator in New Geneva switzerland. They believe if they can produce black holes it will prove the existance of extra demensions. Very interesting.

and what do they wanna do with it once it was created? i doubt that black wholes, man-made or not are very healthy for the earth...

[Vilkate]

ha ha, and the next thing we know - there is a hole where Switzerland used to be!

I would imagine the energy required to create a black hole would be a sum the is simply massive.
however I did find a short article on it as hard as it is to follow

The RHIC fireball as a dual black hole
Authors: Horatiu Nastase
Comments: 10 pages, latex, references added, typos corrected, comments on RHIC experimental observations added, definition of a corrected

We argue that the fireball observed at RHIC is (the analog of) a dual black hole. In previous works, we have argued that the large $s$ behaviour of the total QCD cross section is due to production of dual black holes, and that in the QCD effective field theory it corresponds to a nonlinear soliton of the pion field. Now we argue that the RHIC fireball is this soliton. We calculate the soliton (black hole) temperature, and get $T=4a <m_{\pi}>/\pi$, with $a$ a nonperturbative constant. For $a=1$, we get $175.76 MeV$, compared to the experimental value of the fireball ``freeze-out'' of about $176 MeV$. The observed $\eta/ s$ for the fireball is close to the dual value of $1/4\pi$. The ``Color Glass Condensate'' (CGC) state at the core of the fireball is the pion field soliton, dual to the interior of the black hole. The main interaction between particles in the CGC is a Coulomb potential, due to short range pion exchange, dual to gravitational interaction inside the black hole, deconfining quarks and gluons. Thus RHIC is in a certain sense a string theory testing machine, analyzing the formation and decay of dual black holes, and giving information about the black hole interior.  

and I found this at http://www.arxiv.org/abs/hep-th/0501068

I also found something that appears to be similar to this and has a video that isn't that interesting but maybe someone on this site actually knows about this stuff http://www.bnl.gov/RHIC/

i think if they will be successful on the blackhole thing, it will create a vaccum effect.

I would assume a team sharp enough to engineer a black hole in a lab would think of that, and have measures in place, but I agree, it is still seems like something that shouldn't be played with. There are many dangerous physics experiments whose results are not known ahead of time- like the first A-bomb- Openheimer pointed out that there was no way of knowing it would not blow up the entire earth in a chain reaction, but they did it anyhow. I think this is in a similar class.

I think I remember reading something about this, but I think they black holes they create are not massive enough to cause any destruction, black holes are only as strong as how much mass they contain, if they create a black hole out of 1 gram of some element, it's nothing to worry about like a black hole that already sucked up solar systems worth of material.

I agree that the danger of the black hole is proportional to its total mass, but the density of that mass is another apsect that defines it.

There is a cave in a place called Galax where a large deposit of localized dense material (prob. iridium) in the ceiling actually competes with the gravity of the earth, insofar as the center of gravity of the earth is hundreds of miles away in the core.

In 1996, Virginia spelunkers Tim Doyle and Vaughan James were exploring unmapped areas of a cave near Galax, Virginia when they entered a chamber in which they suddenly felt light on their feet. They quickly discovered to their utter amazement that, in this chamber, they could effortlessly leave the ground merely by "pushing off," and rise high into the chamber before gently falling back to the floor. What Doyle and James had discovered was soon confirmed by government scientists to be a "gravity hole," a phenomena that had, up to that point, only been theorized by geophysicists. The gravity hole is essentially a region of reduced gravity which results from an unusually-dense mass immediately above the area, suspected in this case to involve a high concentration of the element iridium.

The Galax low-gravity cavern has since become a hotbed of controversy and dispute over ownership and intended use. A court battle currently rages between landowners wanting to create an amusement park which features the "Low-G" cavern as a centerpiece, and the federal government who has laid claim to the cavern with the intention of researching the gravity hole phenomenon further and potentially using it for astronaut training.

although the black hole might only be a gram or so, the super-dense concentration of its matter would still cause it to attract nearby particles moreso than normal matter would, giving it the potential for growth. In order to be truly safe, I would suppose that the black hole would have to be made in such a way that it collapes shortly after coming into existence, although physics is not my major.

The Gravity Hole is a hoax:

It got me interested first time I read about it though .

[Stillwater]

That is pretty funny, MisterJingo; I thought the picture was a bit goofy  

I thought this was a real phenomenon for years, so much so that I used it as a citation, lol. I thought I even recalled a reference on the telly, but that might have been to some sort of magnetic anomoly instead.

But you must be right, as the site you posted refers to the site I posted as the source of the disinformation

I actually told people about this because I was so amazed  :redface:. This is before I found out about it being a hoax

The thing is that the energy to create a lasting black hole is enormous.  The black holes that they are creating are very small, no more than several millimeters wide TOPS.  They disappear in under a second and they don't have the capacity to do much damage.
