How to create a black hole?

Yo!

According to John Titor it should be possible to create an artificial black hole by using a particle accelerator. So far I have not heard or read anything that these black holes are really made at CERN. Does anybody knows scientific articles about this subject? Are there any attemps made in order to create a black hole at Cern? I think there should be if Titor is not hoax.

Could such a black hole be used as a power generator and if yes how does this happen in real life?

Many thanks for all advise. :-)

I did read an article that said that mini black holes will be produced at CERN but they will be microscopic and will only last for a fraction of a second before evaporating via Hawking radiation. I have the link but the article does not seem to be up any longer. Do a google search for "CERN to spew black holes". It was very interesting. It basically said that the mini black holes will be produced and could help to reviel hidden dimensions of space. I doubt that they will be used along the lines of the Titor story.. but then again, I don't believe the Titor story to be true.
 
Many thanks for reply...yes I found that miniscale black holes are indeed made at Cern. This is quite remarkble achievement I think. Some scientist believe that playing with these singularities is not riskless game! Better be carefull at there! Indeed a singularity which is out of control maybe dangerous...this is easy to believe. No wonder that people of 2036 do not like the idea to produce energy by using a black hole.

If they can make little black holes maybe larger and more usable singularities can be made in the near future.

What if we make a small black hole which then could be smashed to another black hole ...and then again to another black hole. I wonder if this could lead to a chain reaction which could lead to a larger singularity...which is needed for power plant or even time machine...maybe...you never know.

The Large Hadronic Collider (LHC), which is to be the world’s highest energy particle accelerator, is currently being constructed at the CERN laboratory in Geneva, Switzerland. The machine was designed to be high enough in energy to produce a completely new type of particle, the Higgs boson, which is considered to be the missing puzzle-piece in the Standard Model of particle interactions. According to current theoretical thinking, it is the Higgs particle that gives mass to all the other particles, quarks, leptons, etc., in the current bestiary of fundamental particles.

However, there are new theoretical predictions that when the new accelerator goes into operation, the LHC's proton-proton collisions may also make something even more exotic: black holes. This column is about the possibility of black hole production at the LHC.

Note that at the end of the article, you'll find two arxiv preprints.
 
The idea of using micro black holes to create wormholes seems to be supported by several scientists.

Here you'll find two recent articles how to create traversable wormholes. The author is not really interested in time machines, so he is generally silent about that subject.

"The theoretical construction of a traversable wormhole from a Schwarzschild black hole is described, using analytic solutions in Einstein gravity. The matter model is pure phantom radiation (pure radiation with negative energy density) and the idealization of impulsive radiation is employed."

How to make a traversable wormhole from a Schwarzschild black hole by Sean A. Hayward and Hiroko Koyama.

"Analytic solutions are presented which describe the construction of a traversable wormhole from a Schwarzschild black hole, and the enlargement of such a wormhole, in Einstein gravity. The matter model is pure radiation which may have negative energy density (phantom or ghost radiation) and the idealization of impulsive radiation (infinitesimally thin null shells) is employed."

Below two papers how to create Morris-Thorne wormholes and ringholes.

"It is shown that in a classical spacetime with multiply connected space slices having the topology of a torus, closed timelike curves are also formed. We call these spacetime ringholes. Two regions on the torus surface can be distinguished which are separated by angular horizons. On one of such regions (that which surrounds the maximum circumference of the torus) everything happens like in spherical wormholes, but the other region (the rest of the torus surface), while still possessing a chronology horizon and non-chronal region, behaves like a coverging, rather than diverging, lens and corresponds to an energy density which is always positive for large speeds at or near the throat. It is speculated that a ringhole could be converted into a time machine to perform time travels by an observer who would never encounter any matter that violates the classical averaged weak energy condition. Based on a calculation of vacuum fluctuations, it is also seen that the angular horizons can prevent the emergence of quantum instabilities near the throat."

Ringholes and closed timelike curves by Pedro F. González-Díaz.

"The effects that the present accelerating expansion of the universe has on the size and shape of Lorentzian wormholes and ringholes are considered. It is shown that, quite similarly to how it occurs for inflating wormholes, relative to the initial embedding-space coordinate system, whereas the shape of the considered holes is always preserved with time, their size is driven by the expansion to increase by a factor which is proportional to the scale factor of the universe. In the case that dark energy is phantom energy, which is not excluded by present constraints on the dark-energy equation of state, that size increase with time becomes quite more remarkable, and a rather speculative scenario is here presented where the big rip can be circumvented by future advanced civilizations by utilizing sufficiently grown up wormholes and ringholes as time machines that shortcut the big-rip singularity."

Wow, MadIce. That's a lot of stuff.

Anyway...

"What if we make a small black hole which then could be smashed to another black hole ...and then again to another black hole. I wonder if this could lead to a chain reaction which could lead to a larger singularity...which is needed for power plant or even time machine...maybe...you never know."

I beleive that what happens when two black holes meet is thus: a huge explosion of energy, far larger than even the death-screem of a large star collapsing and becoming a black hole.

With tiny black holes, the energy levels would probably be more managable.
 
The point of those articles is that you don't need black holes collisions. You can enlarge a micro black hole instead by adding energy. Looks a bit safer.
 
Yo!

Many thanks for your reply and efforts...unfortunately I am only an industrial designer and therefore do not understand the mathematics here...I have never understood the mathematics behind general theory of relativity. However I do understand the special theory of relativity but its quite simple compared to general theory of relativity.

I can draw and create art but this physics is so hard to understand because of its really complex mathematics.

But it seems that time machine is possible to do and black holes can be done...interesting.

I am not sure if time machines can be made. There is theory (like the last two papers I have shown) that time travel can be made a reality. But Krasnikov, another scientist in that field, believes wormholes can only be used for shortcuts in space and that time travel is impossible. Others believe wormholes are unphysical. Scientists are interested in the subject, because it might tell us more about gravity, matter, the big bang and other questions science doesn't have an answer for yet.
