Collider Triggers End-of-World Fears
From the flagellants of the Middle Ages to the doomsayers of Y2K, humanity has always been prone to good old-fashioned the-end-is-nigh hysteria. The latest cause for concern: that the earth will be destroyed and the galaxy gobbled up by an ever-increasing black hole next week.
This summer, after 25 years of preparation, scientists at CERN, the world's largest particle physics laboratory, will try to re-create the conditions produced by the Big Bang.
On Sept. 10, scientists at the European Organization for Nuclear Research (CERN) laboratory in Geneva, Switzerland, will switch on the Large Hadron Collider (LHC) — a $6 billion particle accelerator that will send beams of protons careening around a 17-mile underground ring, crash them into each other to re-create the immediate aftereffects of the Big Bang, and then monitor the debris in the hope of learning more about the origins and workings of the universe. Next week marks a low-power run of the circuit, and scientists hope to start smashing atoms at full power by the end of the month.
Critics of the LHC say the high-energy experiment might create a mini black hole that could expand to dangerous, Earth-eating proportions. On Aug. 26, Professor Otto Rossler, a German chemist at the Eberhard Karis University of Tubingen, filed a lawsuit against CERN with the European Court of Human Rights that argued, with no understatement, that such a scenario would violate the right to life of European citizens and pose a threat to the rule of law. Last March, two American environmentalists filed a lawsuit in Federal District Court in Honolulu seeking to force the U.S. government to withdraw its participation in the experiment. The lawsuits have in turn spawned several websites, chat rooms and petitions — and led to alarming headlines around the world (Britain's Sun newspaper on Sept. 1: "End of the World Due in 9 Days").
Should we be scared? No. In June, CERN published a safety report, reviewed by a group of external scientists, ruling out the possibility of dangerous black holes. It said that even if tiny black holes were to be formed at CERN — a big if — they would evaporate almost instantaneously due to Hawking Radiation, a phenomenon named for the British physicist Stephen Hawking, whose theories show that black holes not only swallow up the light, energy and matter around them, but also leak it all back out at an accelerating pace. According to Hawking, if tiny black holes occurred at CERN, they would evaporate before they got a chance to do any damage. (Even if Hawking's theories prove to be wrong — no one has yet witnessed black-hole evaporation — scientists at CERN say the LHC's collisions are already known to be harmless: an equivalent amount of energy is produced hundreds of thousands of times a day by cosmic rays colliding with the earth and other objects in the cosmos — always without incident.)... more From the flagellants of the Middle Ages to the doomsayers of Y2K, humanity has always been prone to good old-fashioned the-end-is-nigh... more -
Closest look at giant black hole in the centre of the Milky Way
Astronomers have taken the closest look ever at the giant black hole in the centre of the Milky Way. By combining telescopes in Hawaii, Arizona, and California, they detected structure at a tiny angular scale of 37 micro-arcseconds - the equivalent of a baseball seen on the surface of the moon, 240,000 miles distant. These observations are among the highest resolution ever done in astronomy.
'This technique gives us an unmatched view of the region near the Milky Way's central black hole,' said Sheperd Doeleman of MIT, first author of the study that was published in the 4 September issue of the journal Nature.
'No one has seen such a fine-grained view of the galactic centre before,' agreed co-author Jonathan Weintroub of the Harvard-Smithsonian Centre for Astrophysics (CfA). 'We've observed nearly to the scale of the black hole event horizon - the region inside of which nothing, including light, can ever escape.'
Using a technique called Very Long Baseline Interferometry (VLBI), a team of astronomers led by Doeleman employed an array of telescopes to study radio waves coming from the object known as Sagittarius A* (A-star). In VLBI, signals from multiple telescopes are combined to create the equivalent of a single giant telescope, as large as the separation between the facilities. As a result, VLBI yields exquisitely sharp resolution.
The Sgr A radio emission, at a wavelength of 1.3 mm, escapes the galactic centre more easily than emissions at longer wavelengths, which tend to suffer from interstellar scattering. Such scattering acts like fog around a street lamp, both dimming the light and blurring details. VLBI is ordinarily limited to wavelengths of 3.5 mm and longer; however, using innovative instrumentation and analysis techniques, the team was able to tease out this remarkable result from 1.3-mm VLBI data.
The team clearly discerned structure with a 37 micro-arcsecond angular scale, which corresponds to a size of about 30 million miles (or about one-third the earth-sun distance) at the galactic centre. With three telescopes, the astronomers could only vaguely determine the shape of the emitting region. Future investigations will help answer the question of what, precisely, they are seeing: a glowing corona around the black hole, an orbiting 'hot spot,' or a jet of material. Nevertheless, their result represents the first time that observations have gotten down to the scale of the black hole itself, which has a 'Schwarzschild radius' of 10 million miles....more Astronomers have taken the closest look ever at the giant black hole in the centre of the Milky Way.

More Evidence for Black Holes: Hubble Images Solve Galactic Filament Mystery
A tangle of spidery filaments stretches outward from the giant elliptical galaxy NGC 1275 as if they were dendrites of an intergalactic nerve cell.
NGC 1275, located 235 million light-years from Earth near the center of a clump of galaxies known as the Perseus cluster, has posed a puzzle: How have these filaments, which are made of gas much cooler than the surrounding intergalactic cloud, persisted for perhaps 100 million years? Why haven’t they warmed, dissipated or collapsed to form stars?
Images taken by the Hubble Space Telescope, with 10 times the resolution of earlier photographs, reveal that the filaments, about 1,500 light-years wide and hundreds of thousands of light-years long, are themselves made of finer threads – smaller structures about 200 light-years wide and 20,000 light-years long. The cold gas is pushed out by waves of radiation emanating from the giant black hole at the center of the galaxy. Small is relative, of course. Each thread contains as much mass as one million Suns.
With the new information, a team led by Andrew C. Fabian, an astrophysicist at the University of Cambridge in England calculated that weak magnetic fields, about one-ten-thousandth as strong as the Earth’s field, exert enough force on the charged particles in the threads to keep them together, thus perhaps answering the puzzle.
“The things tie together very well,” Dr. Fabian said.
The findings appear in the Aug. 21 issue of the journal Nature. A tangle of spidery filaments stretches outward from the giant elliptical galaxy NGC 1275 as if they were dendrites of an intergalacti... more -
CERN Council looks forward to LHC start-up
Scare-mongers have been spreading the rumor that this huge particle accelerator is going to produce a black-hole which will engulf the earth, the moon, etc. They say that it is going to reproduce the Big Bang. Both assertions are absolutely wrong, of course.
In case the first assertion is right, since I live right next to the accelerator, I'll be among the first to enter the black hole - I'll then post to Current to let you all know what it looks like and what it feels like, and I'll even upload some photos. ;) Scare-mongers have been spreading the rumor that this huge particle accelerator is going to produce a black-hole which will engulf the... more -

Source of Mysterious Antimatter Found
Antimatter, which annihilates matter upon contact, seems to be rare in the universe. Still, for decades, scientists had clues that a vast cloud of antimatter lurked in space, but they did not know where it came from.
The mysterious source of this antimatter has now been discovered ? stars getting ripped apart by neutron stars and black holes.
