And now for something completely differ't
Computer generated music like something you have heard before.
Not natural and unnatural sounds relpicated from programing but played on real instruments. Robots Play their Nonexistent Hearts out in Student Orchestra Robot orchestra marries music and machines (video) -- Engadget Kind of a new approach to old music. A true orchestra, but electronic. Cool |

Black Holes Spin Faster and Faster http://www.scientificcomputing.com/n...er-052411.aspx An artist’s impression of the jets emerging from a supermassive black hole at the centre of the galaxy PKS 0521-36. Courtesy of Dana Berry / STScITwo UK astronomers have found that the giant black holes in the center of galaxies are on average spinning faster than at any time in the history of the Universe. Alejo Martinez-Sansigre of the University of Portsmouth and Steve Rawlings of the University of Oxford made the new discovery by using radio, optical and X-ray data. They publish their findings in the journal Monthly Notices of the Royal Astronomical Society. There is strong evidence that every galaxy has a black hole in its center. These black holes have masses of between a million and a billion Suns and so are referred to as ‘supermassive’. They cannot be seen directly, but material swirls around the black hole in a so-called accretion disk before its final demise. That material can become very hot and emit radiation including X-rays that can be detected by space-based telescopes whilst associated radio emission can be detected by telescopes on the ground. As well as radiation, twin jets are often associated with black holes and their accretion disks. There are many factors that can cause these jets to be produced, but the spin of the supermassive black hole is believed to be important. However, there are conflicting predictions about how the spins of the black holes should be evolving and until now this evolution was not well understood. Martinez-Sansigre and Rawlings compared theoretical models of spinning black holes with radio, optical and X-ray observations made using a variety of instruments and found that the theories can explain very well the population of supermassive black holes with jets. Using the radio observations, the two astronomers were able to sample the population of black holes, deducing the spread of the power of the jets. By estimating how they acquire material (the accretion process) the two scientists could then infer how quickly these objects are spinning. The observations also give information on how the spins of supermassive black holes have evolved. In the past, when the Universe was half its the present size, practically all of the supermassive black holes had very low spins, whereas nowadays a fraction of them have very high spins. So on average, supermassive black holes are spinning faster than ever before. This is the first time that the evolution of the spin of the supermassive black holes has been constrained and it suggests that those supermassive black holes that grow by swallowing matter will barely spin, while those that merge with other black holes will be left spinning rapidly. Commenting on the new results, Martinez-Sansigre said, "The spin of black holes can tell you a lot about how they formed. Our results suggest that in recent times a large fraction of the most massive black holes have somehow spun up. A likely explanation is that they have merged with other black holes of similar mass, which is a truly spectacular event, and the end product of this merger is a faster spinning black hole." Rawlings added, “Later this decade we hope to test our idea that these supermassive black holes have been set spinning relatively recently. Black hole mergers cause predictable distortions in space and time — so-called gravitational waves. With so many collisions, we expect there to be a cosmic background of gravitational waves, something that will change the timing of the pulses of radio waves that we detect from the remnants of massive stars known as pulsars. If we are right, this timing change should be picked up by the Square Kilometer Array, the giant radio observatory due to start operating in 2019.” |

Is Warp Drive in our near future? William Shatner may live long enough to see it Experiment Traps Antimatter for 1000 Seconds In a paper published online by the journal Nature Physics, the ALPHA experiment at CERN reported that it has succeeded in trapping antimatter atoms for over 16 minutes: long enough to begin to study their properties in detail. ALPHA is part of a broad program at CERN’s antiproton decelerator (AD) investigating the mysteries of one of nature’s most elusive substances. Today, we live in a universe apparently made entirely of matter, yet at the big bang matter and antimatter would have existed in equal quantities. Nature seems to have a slight preference for matter, which allows our universe and everything in it to exist. One way of investigating nature’s preference for matter is to compare hydrogen atoms with their antimatter counterparts, and that’s what makes today’s result important. “We can keep the antihydrogen atoms trapped for 1000 seconds,” explained ALPHA spokesperson Jeffrey Hangst of Aarhus University. “This is long enough to begin to study them - even with the small number that we can catch so far.” In the paper, some 300 trapped antiatoms are reported to have been studied. The trapping of antiatoms will allow antihydrogen to be mapped precisely using laser or microwave spectroscopy so that it can be compared to the hydrogen atom, which is among the best-known systems in physics. Any difference should become apparent under careful scrutiny. Trapping antiatoms could also provide a complementary approach to measuring the influence of gravity on antimatter, which will soon be investigated with antihydrogen by the AEgIS experiment. Another important consequence of trapping antihydrogen for long periods is that the antiatoms have time to relax into their ground state, which will allow ALPHA to conduct the precision measurements necessary to investigate a symmetry known as CPT. Symmetries in physics describe how processes look under certain transformations. C, for example, involves swapping the electric charges of the particles involved in the process. P is like looking in the mirror, while T involves reversing the arrow of time. Individually, each of these symmetries is broken – processes do not always look the same. CPT, however, says that a particle moving forward through time in our universe should be indistinguishable from an antiparticle moving backwards through time in a mirror universe, and it is thought to be perfectly respected by nature. CPT symmetry requires that hydrogen and antihydrogen have identical spectra. “Any hint of CPT symmetry breaking would require a serious rethink of our understanding of nature,” said Hangst. “But half of the universe has gone missing, so some kind of rethink is apparently on the agenda. ” The next step for ALPHA is to start performing measurements on trapped antihydrogen, and this is due to get underway later this year. The first step is to illuminate the trapped anti-atoms with microwaves, to determine if they absorb exactly the same frequencies (or energies) as their matter cousins. “If you hit the trapped antihydrogen atoms with just the right microwave frequency, they will escape from the trap, and we can detect the annihilation – even for just a single atom,” explained Hangst. “This would provide the first ever look inside the structure of antihydrogen – element number 1 on the anti-periodic table.” "Fasinating" http://www.scientificcomputing.com/n...ds-060811.aspx Sorry 180 but no pictures. You will have to read text. And just believe. |

Specifically art and censorship, is smut in the eye of the beholder or can a general principal be applied that would apply to all art in a given culture. Is this considered art or too much stone exposure? https://www.crossfireforum.org/galle...e_Ma399_n4.jpg We'll leave it to our censors to decide.;) |
