From PhysOrg.com:Einstein equations indicate possibility of black hole formation at the LHC
April 6, 2010 By Miranda Marquit
(PhysOrg.com) -- One of the concerns that has been voiced about the Large Hadron Collider (LHC), is that it could result in the formation of black holes that could destroy the world. While most scientists dismiss claims that anything produced in the LHC would destroy the planet, there are some that think that black formation could be seen with LHC collisions of sufficiently high energy. This idea has gotten a further boost from recent efforts by Matthew Choptuik at the University of British Columbia in Vancouver, and Frans Pretorius, at Princeton University in New Jersey.
“What we did was a calculation,” Choptuik tells PhysOrg.com. “We solved some of the Einstein field equations describing head on soliton collisions at certain energies.” Choptuik and Pretorius present their work, and their conclusions, in Physical Review Letters: “Ultrarelativistic Particle Collisions.”
“Our calculation produced results that most were expecting, but no one had done the calculation before. People were just sort of assuming that it would work out,” Choptuik says. “Now that these simulations have been done, some scientists will have a better idea of what to look for in terms of trying to see if black holes are formed in LHC collisions.”
Choptuik points out that there has been an effort for more than 50 years to marry particle physics with the idea of gravity. “At the level of classical physics we think we understand gravity pretty well,” he explains. “However, at the quantum mechanical level, gravity is not at all well understood. Scientists have been looking for a way to understand quantum gravity in the same way as we understand how the smallest particles work on a quantum level. While solving these equations doesn’t answer all the questions, it does substantiate what we have already assumed.”

If they get one and feed it well, maybe they can keep it from evaporating? |

If the LCH can make them, then it is likely they already appear in our atmosphere millions of times a second from all the high energy collisions. If such a small black hole was going to be a threat to the planet then it seems like we'd all be living in a singularity right now.

I am getting flashbacks of reading David Brin's Earth. From what I understand the planet isn't dense enough to keep a micro-blackhole going.

| They say it can't happen. Oh yeah! Imagine the look on their faces when the black hole feeds on the LHC! One wrong collision and poof, the whole collider vanishes. Running that experiment again can get expensive. Maybe they should have had a priest mumble a prayer and throw some holy water when they had their opening ceremony. A little insurance against woo like this. SS |
