Scientists Say Mini-Black Holes Easier to Make | |

(OP) User ID: 33350609 United States 03/12/2013 08:39 PM Report Abusive Post Report Copyright Violation | I partly blame whoever wrote this article because it makes the science sound so blatantly irresponsible. I generally think that particle accelerators are really cool and can do a lot to help our understanding of science. But at what point does "coolness" end and responsibility begins? What if the LHC somehow produces a couple million mini-black holes on accident? And what if they don't really "evaporate"? And how would they react if they were in close proximity to each other? I may not be a physicist...but it sounds like a lot of questions and the article does little to comfort the reader. |

User ID: 31033756 Netherlands 03/13/2013 12:54 AM Report Abusive Post Report Copyright Violation | Much higher energy collisions happen in nature all the time, when high-Z cosmic particles hit the atmosphere. If such collisions produce nano-black holes, such black holes must be harmless. After all, Earth is still here. I'm guessing "sky dose" is the same as "skyshine"...Not really sure about the physics, but I think the faster the particles go the more shielding is needed to protect the outside environment. Quoting: DruDay It goes the other way around as well. They don't want outside radiation to mess with their very sensitive detectors. That's why the big ones are underground.

Anonymous Coward User ID: 18278609 Philippines 03/13/2013 09:55 AM Report Abusive Post Report Copyright Violation | I thought this was pretty interesting...apparently some scientists are saying that the Large Hadron Collider could make mini-black holes a lot easier than previously thought. What's disturbing though is all the "assumptions" being made saying that they are perfectly safe. I've made bold all the disturbing parts. Quoting: DruDay How to create a black hole So far, researchers have detected no black holes at the Large Hadron Collider. Still, theoretical interest in this possibility remains alive. Now, using supercomputers, researchers simulating collisions among particles zipping near the speed of light have shown that black holes could form at lower energies than previously thought. This new discovery is rooted in Einstein's theory of relativity. First, through his famous equation E = mc2, Einstein revealed that mass and energy are related. This means the greater the energy of a particle — say, the faster a particle gets accelerated in a collider — the greater its mass becomes. Next, Einstein's theory explains that mass curves the fabric of space and time, generating the phenomenon known as gravity. As particles zip along within particle colliders, they warp space-timeand can focus energy much as glass lenses focus light. When two particles collide, each one can focus the energy of the other. If scientists use models based on classical relativity that exclude notions of extra dimensions, "one might expect black hole formation at one-third the energy" than previously expected, researcher Frans Pretorius, a theoretical physicist at Princeton University, told LiveScience. Still, conventional physics suggest it would take a quadrillion, or a million-billion, times more energy to form a microscopic black hole than the Large Hadron Collider is capable of, so even a third of that is beyond human reach. Scenarios based on extra dimensions could have black holes form at a lower energy, "but they make no concrete predictions on what it should be," Pretorius said. Risk-free black holes As frightening as black holes might seem, if particle accelerators on Earth can generate them, such infinitesimal entities pose no risk to the planet. "The one common misconception about the small black holes that may form at the Large Hadron Collider is that they would swallow the Earth," Pretorius said. "With about as much confidence as we can say anything in science, this is completely impossible." To start with, theoretical physicist Stephen Hawking calculated all black holes should lose mass over time, giving it off as so-called Hawking radiation. Tiny black holes should shrink via such evaporation faster than they grow by gobbling up matter, dying within a fraction of a second, before they could engorge on any significant amount of matter. Even if one assumes Hawking is wrong and that black holes are more stable than that, the tiny black holes would pose no danger. Because the microscopic black holes would be created within a particle accelerator, they should keep enough speed to escape from Earth's gravity. Moreover, if any get trapped, they are so tiny it would take each one more than the current age of the universe to destroy even a milligram of Earth matter. "These black holes would be too small to consume any significant amount of matter," Pretorius said. Pretorius and his colleague William East detailed their findings online March 7 in the journal Physical Review Letters. [link to news.yahoo.com] it always starts like that |

User ID: 26401157 United States 03/13/2013 10:14 AM Report Abusive Post Report Copyright Violation | Mini-Black holes are impossible. Think about it. The core concept behind a black hole states that it is an object that has such a large mass that it generates a gravitational field so powerful that light cannot even escape, thus rendering it a "black hole", due to the lack of light. Tell me, how can anything "mini" or "nano" or "sub atomic" generate that kind of gravity. Gravity requires mass. Anything "mini" surely doesnt have enough mass. Think about it, black holes have thousands of times the mass of our sun. So, something at the atomic level could have thousands of times the mass of our sun? I dont think so.

Such a large mass compared to its size. It's all about density. A 1 kg ball made of lead will have a greater surface gravity than a 1 kg ball made of iron. Because the lead ball's surface is closer to its centre of mass. If you'd could compress a proton down to below the size of the Schwarzschild radius of such a mass, yes you would have an area of space where gravity would be so high that the escape velocity would exceed the speed of light.
