  • Physicists Puzzle Over Unexpected Findings In "Little" Big Bang

    11/13/2002 9:52:46 PM PST · by sourcery · 32 replies · 391+ views
    Scientists have recreated a temperature not seen since the first microsecond of the birth of the universe and found that the event did not unfold quite the way they expected, according to a recent paper in Physical Review Letters. The interaction of energy, matter, and the strong nuclear force in the ultra-hot experiments conducted at the Relativistic Heavy Ion Collider (RHIC) was thought to be well understood, but a lengthy investigation has revealed that physicists are missing something in their model of how the universe works. "It's the things you weren't expecting that are really trying to tell you something...

    stronomers have gazed out at the universe for centuries, asking why it is the way it is. But lately a growing number of them are dreaming of universes that never were and asking, why not? Why, they ask, do we live in 3 dimensions of space and not 2, 10 or 25? Why is a light ray so fast and a whisper so slow? Why are atoms so tiny and stars so big? Why is the universe so old? Does it have to be that way, or are there places, other universes, where things are different? Once upon a time...

    Gravity waves analysis opens 'completely new sense' PRESS RELEASE Washington University in St. Louis St. Louis, MO. -- Sometime within the next two years, researchers will detect the first signals of gravity waves -- those weak blips from the far edges of the universe passing through our bodies every second. Predicted by Einstein's theory of general relativity, gravity waves are expected to reveal, ultimately, previously unattainable mysteries of the universe. Wai-Mo Suen, Ph.D., professor of physics at Washington University in St. Louis is collaborating with researchers nationwide to develop waveform templates to comprehend the signals to be analyzed.

    "It is widely accepted now that, without a doubt, information is physical and quantum physics provides the rules of that physical behavior," George Mason University computer science professor Richard Gomez told NewsFactor. Alan Turing might be considered the "John Forbes Nash of computer science" -- a troubled young Princeton genius who achieved prominence in the 1950s. Turing published one of the top 10 papers in all of 20th-century science -- "On the Computability of Numbers." He killed himself over a conviction for homosexuality at the height of his genius, but since his death, his definition of "computability" has stood untouched...

    New Scientist ^ | 09:20 22 September 02 | Michael Brooks
    Exclusive from New Scientist Hidden extra dimensions are causing measurements of the strength of gravity at different locations on Earth to be affected by the planet's magnetic field, French researchers say. This is a controversial claim because no one has ever provided experimental evidence to support either the existence of extra dimensions or any interaction between gravity and electromagnetism. But lab measurements of Newton's gravitational constant G suggest that both are real. Newton's constant, which describes the strength of the gravitational pull that bodies exert on each other, is the most poorly determined of the constants of nature. The two...

    Scientists claim antimatter breakthrough Scientists have announced the first large-scale production of antimatter. A team based at the European Organisation for Nuclear Research in Geneva say they have developed a large amount of the substance. Antimatter is a reverse form of ordinary matter. When the two kinds of matter meet they annihilate each other in an enormous burst of energy. It's this process which provides the power source for Starship Enterprise in its film and TV space adventures. Physicists have made only very small quantities of antimatter before. But the CERN team say they have made at least 50,000 atoms...
  • "Runaway Universe" May Collapse In 10 Billion Years, New Studies Predict

    09/17/2002 10:50:04 AM PDT · by sourcery · 82 replies · 591+ views
    The recent discovery that the universe is expanding at an ever-increasing rate has led many astronomers to forecast a dark and lonely future for our galaxy. According to some predictions, the rapidly accelerating universe will cause all galaxies to run away from each other until they are no longer visible. In this widely accepted scenario, our own Milky Way will become an isolated island adrift in a sea of totally black space 150 billion years from now. But two new studies by Stanford University cosmologists suggest that it may be time to rethink this popular view of a "runaway universe."...

    Electric signals can be transmitted at least four times faster than the speed of light using only basic equipment that would be found in virtually any college science department. Scientists have sent light signals at faster-than-light speeds over the distances of a few metres for the last two decades - but only with the aid of complicated, expensive equipment. Now physicists at Middle Tennessee State University have broken that speed limit over distances of nearly 120 metres, using off-the-shelf equipment costing just $500. Jeremy Munday and Bill Robertson made a 120-metre-long cable by alternating six- to eight-metre-long lengths of two...

    Scientists attempt to measure speed of gravity UNIVERSITY OF MISSOURI NEWS RELEASE Posted: September 4, 2002 Ever since Albert Einstein proposed the general theory of relativity in 1916, physicists worldwide have tested the theory's underlying principles. Whil some principles - such as the speed of light is a constant - have been proven, others have enot. Now, through a combination of modern technology, the alignment of a unique group of celestial bodies on Sept. 8, and an experiment conceived by a University of Missouri-Columbia physicist, one more of those principles might soon be proven.

  • Tune in to terahertz

    The Economist ^ | Aug 8th 2002
    Lasers now work at new wavelengths FROM a human point of view, the terahertz frequencies are a curiously barren region of the electromagnetic spectrum. They lie, unexploited, between microwaves at long wavelengths and infra-red at short. They are neglected because no one has developed a convenient source of terahertz radiation. Not yet, anyway. But a laser unveiled by Alessandro Tredicucci of the Scuola Normale Superiore in Pisa, Italy, at the recent International Conference on the Physics of Semiconductors, in Edinburgh, lights the way to the future. Research into terahertz sources has been driven hard by demand from industry. Terahertz frequencies...

    Einstein's relativity theory hits a speed bump August 8 2002 Australian scientists have discovered that light isn't quite as fast as it used to be. But it doesn't mean E=mc2 will be consigned to the dustbin, writes David Wroe. In October, 1971, American physicists took four super-accurate atomic clocks, kept two on the ground and put two on commercial jets flying at 1000 kmh in opposite directions around Earth. When the planes landed, the scientists found what they were hoping for: The clocks on the high-speed journeys were ticking a few billionths of a second behind their stationary friends. Motion,...

    Sydney Morning Herald ^ | August 10 2002 | John Webb
    If the speed of light can slow down, as new findings suggest, scientists may have to think again about some other laws of nature. John Webb writes. Is it outrageous to ask whether the laws of nature have remained the same since the Big Bang created our universe about 14 billion years ago? The great British physicist, Paul Dirac, didn't think so when he suggested the idea in 1927. And he still thought that way when he lectured on the topic at the University of NSW in 1975. However, the reasons for asking the same question today are very different...

    Fusion reactor breaks duration record 10:50 06 August 02 news service A powerful plasma discharge has operated for a world record 210 seconds in an experimental French fusion reactor. The demonstration is a significant step toward the long plasma confinement times needed in a practical fusion reactor. Physicists sustained the three-megawatt electric discharge in the Tore Supra reactor at the Association Euratom-CEA in Cadarache. During that interval, it dissipated more than 600 megajoules of energy, more than twice the previous record, also set by Tore Supra in 1996. The record was broken thanks to an upgrade that added...

    Painstaking observations of a kind of subatomic dance suggest that the universe may contain a shadowy form of matter that has never been seen directly and is unexplained by standard physics theories, a team of scientists working at Brookhaven National Laboratory on Long Island announced yesterday. The studies appear to confirm similar findings the scientists reported last year. The research involves muons, rare subatomic particles similar to electrons but 207 times as heavy. The work has been controversial, though for reasons that have little to do with the experiment itself. Theorists who are not involved in the research, but whose...
