  • Integral challenges physics beyond Einstein

    06/30/2011 1:16:51 PM PDT · by decimon · 12 replies
    European Space Agency ^ | June 30, 2011 | Unknown
    30 June 2011 ESA’s Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein. It has shown that any underlying quantum ‘graininess’ of space must be at much smaller scales than previously predicted. Einstein’s General Theory of Relativity describes the properties of gravity and assumes that space is a smooth, continuous fabric. Yet quantum theory suggests that space should be grainy at the smallest scales, like sand on a beach. One of the great concerns of modern physics is to marry these two concepts into a single theory of quantum gravity. Now, Integral has...
  • 'Tau day' marked by opponents of maths constant pi

    BBC ^ | June 28, 2011 | Jason Palmer
    The mathematical constant pi is under threat from a group of detractors who will be marking "Tau Day" on Tuesday. Tau Day revellers suggest a constant called tau should take its place: twice as large as pi, or about 6.28 - hence the 28 June celebration. Tau proponents say that for many problems in maths, tau makes more sense and makes calculations easier. Not all fans of maths agree, however, and pi's rich history means it will be a difficult number to unseat. "I like to describe myself as the world's leading anti-pi propagandist," said Michael Hartl, an educator and...

    Established Physics Has Another New Fusion Problem June 27, 2011 | 2 Comments Brillouin Energy Corp In Berkeley California has another Low Energy Nuclear Reaction (LENR) method in the development and proving stage. The new method comes at fusion from a different path than the Rossi E-Cat. The reports have the Brillouin at nearly 2 times the energy coming out from that going in. If this is real the established physicists have a new “won’t fit” phenomena to cope with. In the simple explanation the Brillouin technique uses an electromagnetic pulse slamming into hydrogen or H1. The pulse pushes some...

For now, they are called Elements 114 and 116 — permanent names and symbols will be chosen later.People are not likely to run into either of them. Scientists make them in labs by smashing atoms of other elements together to create the new ones...the new ones are short-lived. Atoms of 114 disintegrate within a few seconds, while 116 disappears in a fraction of a second, ..Both elements were discovered by a collaboration of scientists from Livermore and Russia. They...

    University of Vienna ^ | June 24, 2011 | Unknown
    The quantum mechanical entanglement is at the heart of the famous quantum teleportation experiment and was referred to by Albert Einstein as "spooky action at a distance". A team of researchers led by Anton Zeilinger at the University of Vienna and the Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences used a system which does not allow for entanglement, and still found results which cannot be interpreted classically. Their findings were published in the latest issue of the renowned scientific journal Nature. Asher Peres, a pioneer of quantum information theory once remarked jokingly in a...

    In 1893, Orlando Ferguson, a real estate developer based in South Dakota, drew a map of the Earth that combined biblical and scientific knowledge in a unique way. The map accompanied a 92-page lecture that Ferguson — referring to himself as a "professor" — delivered in town after town, traveling far and wide to share his theory of geography, highlighted by his belief that the Earth was flat. Only one fully intact version of Ferguson's map, which represents the Earth as a giant, rectangular slab with a dimpled upper surface, remains. Don Homuth of Salem, Ore., just donated the map...

    When the Swift Gamma Burst Mission spacecraft first detected the flash within the constellation Draco, astronomers thought it was a gamma-ray burst from a collapsing star. On March 31, however, UC Berkeley's Joshua Bloom sent out an email circular suggesting that it wasn't a typical gamma-ray burst at all, but a high-energy jet produced as a star about the size of our sun was shredded by a black hole a million times more massive. Careful analysis of the Swift data and subsequent observations by the Hubble Space Telescope and the Chandra X-ray Observatory confirmed Bloom's initial insight. The details are...

    FAIRFAX, Va., June 15, 2011—George Mason University scientists discovered recently that a phenomenon called a giant magnetic rope is the cause of solar storms. Confirming the existence of this formation is a key first step in helping to mitigate the adverse effects that solar storm eruptions can have on satellite communications on Earth. The discovery was made by associate professor Jie Zhang and his graduate student Xin Cheng using images from the NASA Solar Dynamic Observatory (SDO) spacecraft. Though the magnetic rope was believed to be the cause of these giant eruptions on the Sun, scientists had previously not been...

    Called blue stragglers, these cannibal stars have been spotted in other parts of the Milky Way. They seem to lag in age next to the other stars with which they formed—appearing hotter, and thus younger and bluer. Astronomers suspect blue stragglers look so youthful because they've stolen hydrogen fuel from other stars, perhaps after colliding into their victims. These cannibal stars are routinely found in dense star clusters, where stars have many chances to feed off each other. Now, however, scientists have found blue stragglers in the Milky Way's galactic bulge, a dense region of stars and gas surrounding the...

    With a new printing technique, researchers can now make enough metamaterials to begin fabricating invisibility cloaks and superlenses.A new printing method makes it possible to produce large sheets of metamaterials, a new class of materials designed to interact with light in ways no natural materials can. For several years, researchers working on these materials have promised invisibility cloaks, ultrahigh-resolution "superlenses," and other exotic optical devices straight from the pages of science fiction. But the materials were confined to small lab demonstrations because there was no way to make them in large enough quantities to demonstrate a practical device. "Everyone has,...

    Yahoo ^ | 6/9/11 | AFP
    WASHINGTON (AFP) – A pair of NASA probes wandering in deep space discovered that the outer edge of the solar system contains curious magnetic bubbles and is not smooth as previously thought, astronomers said Thursday. The NASA Voyager twin spacecraft, which launched in 1977, are currently exploring the furthest outlays of the heliosphere, where solar wind is slowed and warped by pressure from other forces in the galaxy, the US space agency said. "Because the sun spins, its magnetic field becomes twisted and wrinkled, a bit like a ballerina's skirt," said astronomer Merav Opher of Boston University. "Far, far away...

    Surprising discovery may offer clues to emergence of high-temperature superconductivityUPTON, NY — Magnetic studies of ultrathin slabs of copper-oxide materials reveal that at very low temperatures, the thinnest, isolated layers lose their long-range magnetic order and instead behave like a “quantum spin liquid” — a state of matter where the orientations of electron spins fluctuate wildly. This unexpected discovery by scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and collaborators at the Paul Scherrer Institute in Switzerland may offer support for the idea that this novel condensed state of matter is a precursor to the emergence of...

    RICHMOND, Va. (June 8, 2011) – A team of Virginia Commonwealth University scientists has discovered a new class of 'superatoms' – a stable cluster of atoms that can mimic different elements of the periodic table – with unusual magnetic characteristics. The superatom contains magnetized magnesium atoms, an element traditionally considered as non-magnetic. The metallic character of magnesium along with infused magnetism may one day be used to create molecular electronic devices for the next generation of faster processors, larger memory storage and quantum computers. In a study published online in the Early Edition of the Proceedings of the National Academy...

I wandered over to the Energy from Thorium discussion board to see how they are dealing with the latest set of facts, and I find many of their comments constructive to the ongoing debate. So I'm cherry picking some of them below, the ones I found most valuable. I think it's important to preserve this discussion because they have had threads on cold fusion pulled before, and this one is getting heated. various excerpts...
