    The most powerful particle accelerator in the world, the Large Hadron Collider, has not yet created any black holes as some have feared, researchers say. Even if this atom smasher does create black holes, there is no danger of those black holes destroying Earth, added scientists of the new study published online March 5 in the journal Physical Review Letters.

    The current thinking regarding black holes is that they have two very simple parts, an event horizon and a singularity. Because a probe cannot be sent inside a black hole to see what is truly going on, researchers have to rely on theories. The singularity theory suffers from what has come to be known as the "information paradox"—black holes appear to destroy information, which would seem to violate the rules of general relativity, because they follow rules of quantum mechanics instead. This paradox has left deep thinking physicists such as Stephen Hawking uneasy—so much so that he and others have...

    Black holes are staples of science fiction and many think astronomers have observed them indirectly. But according to a physicist at the Lawrence Livermore National Laboratory in California, these awesome breaches in space-time do not and indeed cannot exist. Over the past few years, observations of the motions of galaxies have shown that some 70% the Universe seems to be composed of a strange 'dark energy' that is driving the Universe's accelerating expansion. George Chapline thinks that the collapse of the massive stars, which was long believed to generate black holes, actually leads to the formation of stars that contain...

    Stephen Hawking has shocked physicists by admitting “there are no black holes”. In a paper published online, Professor Hawking instead argues there are “grey holes”. “The absence of event horizons means that there are no black holes—in the sense of regimes from which light can't escape to infinity,” he says in the paper, called Information Preservation and Weather Forecasting For Black Holes.He says that the idea of an event horizon, from which light cannot escape, is flawed. He suggests that instead light rays attempting to rush away from the black hole’s core will be held as though stuck on a...

    The Milky Way’s black hole is about to gobble up its first dinner, and astronomers are hoping to have front row seats when it happens. A huge gas cloud, about three times the mass of Earth, is on course to collide with the supermassive black hole at the heart of our galaxy in March. Astronomers expect the gas cloud will swing so close to the black hole that it will heat up to the point where it produces spectacular X-rays.

    Nature ^ | 8/6/13 | Eugenie Samuel Reich
    Black holes can be described by just two fundamental characteristics: mass and spin. Astronomers have been able to measure the objects’ mass for decades, by looking for gravitational effects on the orbits of nearby stars. But measuring spin, which records the angular momentum of the matter that falls into the holes, has proved troublesome, particularly for the supermassive black holes that lie at the centres of galaxies. No light emanates from the black holes’ spinning event horizons, so astronomers instead look for proxies that emit X-rays, such as the swirling disks of matter that feed into some holes. Such indirect...

    Astronomers using ESA's Herschel space observatory have detected emission from the base of black-hole jets for the first time. While studying the black-hole binary system GX 339-4 in a multi-wavelength observation campaign, they noticed changes in the source's X-ray and radio emissions signalling the onset of powerful jets being released from the black hole's vicinity. This prompted the astronomers to observe the source at far-infrared wavelengths with Herschel. As the first observation of emission from jets in a black-hole binary system at these wavelengths, the data have allowed the astronomers to probe the jets down to their base, where the...

Using new calculations and previous observations of our Milky Way and other galaxies, “We found black holes grow enormously as a result of sucking in captured binary star partners,” said Ben Bromley from the University of Utah in Salt Lake City. “I believe this has got to be the dominant method for growing supermassive black holes,” he said. “There...

    Initial results from high-energy proton collisions at the Large Hadron Collider offer first glimpse of physics at new energy frontier.In December, the Large Hadron Collider, the world’s largest particle accelerator, shattered the world record for highest energy particle collisions. This week, team led by researchers from MIT, CERN and the KFKI Research Institute for Particle and Nuclear Physics in Budapest, Hungary, completed work on the first scientific paper analyzing the results of those collisions. Its findings show that the collisions produced an unexpectedly high number of particles called mesons — a factor that will have to be taken into account...
  • Search for microscopic black hole signatures at the Large Hadron Collider [String Theory Fails]

    CERN ^ | 15 December 2010
    The CMS experiment at CERN’s Large Hadron Collider (LHC) has completed a search for microscopic black holes produced in high-energy proton-proton collisions. No evidence for their production was found and their production has been excluded up to a black hole mass of 3.5-4.5 TeV (1012 electron volts) in a variety of theoretical models. Microscopic black holes are predicted to exist in some theoretical models that attempt to unify General Relativity and Quantum Mechanics by postulating the existence of extra “curled-up” dimensions, in addition to the three familiar spatial dimensions. At the high energies of the Large Hadron Collider, such theories...

    The science blog Cosmic Variance has a great rundown of what the LHC could find. At the top of this list is the Higgs boson, which is the only particle in the Standard Model (the theory that describes the fundamental interactions between the particles that make up all matter), that hasn't yet been detected. The site thinks there is a 95 percent chance the LHC finds this particle, and that could lead to a much better understanding of how our universe works. Other notable possibilities on Cosmic Variance's list include finding extra dimensions (these could be so-called "warped" hidden dimensions...
  • 'Monster' Black Holes Activate When Galaxies Collide

    Enormous black holes, some of the most powerful sources of radiation in the universe, apparently switch on after galaxies collide, researchers have found. The centers of as many as a tenth of all galaxies generate more energy than can be explained by stars, with some of these "active galactic nuclei" releasing more radiation than the entire Milky Way galaxy combined, but from a space no larger than our solar system. Astronomers suspect this energy is released when matter falls into giant, supermassive black holes that are up to billions of times the mass of our sun at these galaxies'...

    Astronomers have detected the deepest note ever generated in the cosmos, a B-flat flying through space like a ripple on an invisible pond. No human will actually hear the note, because it is 57 octaves below the keys in the middle of a piano. The detection was made with NASA's Chandra X-ray Observatory and announced at a press conference today. The note strikes an important chord with astronomers, who say it may help them understand how the universe's largest structures, called galaxy clusters, evolve. The sound waves appear to be heating gas in the Perseus galaxy cluster, some 250 million...

Fujioka et al., Nature Physics, Advance Online Publication A team of researchers has created conditions analogous to those found outside of a black hole by blasting a plastic pellet with high-energy laser beams. The advance should sharpen insights into the behavior of matter and energy in extreme conditions. Astronomers can't observe black holes directly because their immense gravity won't let light escape. Instead, they have focused on what...

    IT IS the ultimate cosmic villain: space and time come to an abrupt end in its presence and the laws of physics break down. Now it seems a "naked" black hole may yet emerge in our universe, after spinning away its event horizon.

    Enlarge ImageOutlier. Astronomers think they have found an intermediate-mass black hole (bright blue object) just outside a distant galaxy. Credit: Heidi Sagerud Heavyweight and lightweight black holes abound in the universe, but nobody has detected a middleweight--and some scientists argue they don't exist. Now, astronomers say they have found the first conclusive evidence for one of these elusive objects at the fringe of a distant galaxy. Estimated to be at least 500 times more massive than the sun, the discovery could plug a large gap in the cosmic menagerie, though it leaves unanswered questions about this type of black...

    (PhysOrg.com) -- A pair of astronomers from Texas and Germany have used a telescope at The University of Texas at Austin's McDonald Observatory together with Hubble Space Telescope and many other telescopes around the world to uncover new evidence that the largest, most massive galaxies in the universe and the supermassive black holes at their hearts grew together over time."They evolved in lockstep," said The University of Texas at Austin's John Kormendy, who co-authored the research with Ralf Bender of Germany's Max-Planck-Institute for Extraterrestrial Physics and Ludwig Maximilians University Observatory. The results are puiblished in this week's issue of Astrophysical...
