  • New Exotic Particle Could Help Explain What Holds Matter Together

    A new exotic particle has been hiding out amidst the gobs of data collected by the world's largest atom smasher, physicists have discovered. The new particle, called Ds3*, is a meson — a type of unstable particle made of one quark and one antiquark. Quarks are subatomic particles and are the most basic building blocks of matter that make up protons and neutrons. They're held together by the strong interaction, or strong force, that is one of the four fundamental forces in nature. (Electromagnetism, weak interaction and gravity are the other three.) No stable form of matter would exist without...
  • Lockheed Martin makes fusion breakthrough

    Hidden away in the secret depths of the Skunk Works, a Lockheed Martin research team has been working quietly on a nuclear energy concept they believe has the potential to meet, if not eventually decrease, the world’s insatiable demand for power. Dubbed the compact fusion reactor (CFR), the device is conceptually safer, cleaner and more powerful than much larger, current nuclear systems that rely on fission, the process of splitting atoms to release energy. Crucially, by being “compact,” Lockheed believes its scalable concept will also be small and practical enough for applications ranging from interplanetary spacecraft and commercial ships to...

    Lockheed Martin, the aerospace and defense conglomerate based in Bethesda, Md., is claiming to have made a major breakthrough in nuclear fusion, which could lead to development of reactors small enough to fit on the back of a truck within a decade. In the simplest terms, nuclear fission breaks a single atom into two whereas nuclear fusion combines two atoms into one. Fusion, the holy grail of nuclear power, creates three to four times as much energy as fission. More importantly, fusion’s key advantage over fission is that it does not produce cancer-causing radioactive waste. (VIDEO-AT-LINK)Tom McGuire, who heads the...

    Phys.Org ^ | 10/10/2014 | by Michelle Ma & Provided by University of Washington
    Fusion energy almost sounds too good to be true – zero greenhouse gas emissions, no long-lived radioactive waste, a nearly unlimited fuel supply. Perhaps the biggest roadblock to adopting fusion energy is that the economics haven't penciled out. Fusion power designs aren't cheap enough to outperform systems that use fossil fuels such as coal and natural gas. University of Washington engineers hope to change that. They have designed a concept for a fusion reactor that, when scaled up to the size of a large electrical power plant, would rival costs for a new coal-fired plant with similar electrical output.

    New research from the University of Western Australia reveals that the amount of dark matter in the Milky Way is half as much as previously thought. Australian astronomers used a method developed almost 100 years ago to discover that the weight of dark matter in our own galaxy is 800,000,000,000 (or 8 x 1011) times the mass of the Sun. They probed the edge of the Milky Way, looking closely, for the first time, at the fringes of the galaxy about 5 million billion kilometers from Earth.

    In 1909, Ernest Rutherford, Hans Geiger and Ernest Marsden took a piece of radium and used it to fire charged particles at a sheet of gold foil. They wanted to test the then-dominant theory that atoms were simply clusters of electrons floating in little seas of positive electrical charge (the so-called ‘plum pudding’ model). What came next, said Rutherford, was ‘the most incredible event that has ever happened to me in my life’. Despite the airy thinness of the foil, a small fraction of the particles bounced straight back at the source – a result, Rutherford noted, ‘as incredible as...

    The new Majorana particle showed up inside a superconductor, a material in which the free movement of electrons allows electricity to flow without resistance. The research team, led by Ali Yazdani of Princeton University, placed a long chain of iron atoms, which are magnetic, on top of a superconductor made of lead. Normally, magnetism disrupts superconductors, which depend on a lack of magnetic fields for their electrons to flow unimpeded. But in this case the magnetic chain turned into a special type of superconductor in which electrons next to one another in the chain coordinated their spins to simultaneously satisfy...

In the modern world, we are instead told a convincing scientific story: Big Bang theory, first proposed in 1927 by the Belgian Roman Catholic priest Georges Lemaître.

We trace this movement back in space and time to nearly the original point of...

    LONDON: Stephen Hawking has recently warned that the God particle or Higgs boson has the potential to obliterate the universe. The 72-year-old cosmologist said Higgs boson could become unstable at very high energy levels, which would lead to a "catastrophic vacuum decay" causing space and time to collapse and that there would not be any warning to the danger, the Daily Express reported. Speaking in the preface to a new book called Starmus, the Cambridge-educated scientist said that the Higgs potential has the worrisome feature that it might become mega-stable at energies above 100bn giga-electron-volts (GeV). However, Hawking did also...

It's called the EmDrive and everyone said it was impossible because it goes against classical mechanics. But the fact is that the quantum vacuum plasma thruster works and scientists can't explain why. Shawyer's engine is extremely light and simple. It provides a thrust by "bouncing microwaves around in a closed container." The microwaves are generated using electricity that can be provided by solar energy. No propellant is necessary, which means that this thrusters can work forever unless a hardware failure occurs. If real, this would be...

    The University of Maryland physicist believes the delay could have been because the light was in fact slowed as it travelled due to something known as 'vacuum polarisation'. During this phenomenon, photons break down to something known as ‘positrons’ and electrons for a split second. before combining together again. When they split, quantum mechanics creates a gravitational potential between the pair of ‘virtual’ particles. Dr Franson argues that the process might have a gradual impact on the speed of the photon, meaning that over 168,000 light years, the photons may have suffered a near five-hour delay.

    Albert Einstein once told a friend that quantum mechanics doesn't hold water in his scientific world view because "physics should represent a reality in time and space, free from spooky actions at a distance." That spooky action at a distance is entanglement, a quantum phenomenon in which two particles, separated by any amount of distance, can instantaneously affect one another as if part of a unified system. Now, scientists have successfully hijacked that quantum weirdness -- doing so reliably for the first time -- to produce what many sci-fi fans have long dreamt up: teleportation.

The findings provide the needed confirmation to their previous discovery of neutrino oscillation and give the most precise measurement yet of neutrino mass. “These findings show that the Standard Model needs to be modified to better explain the fundamental forces that make up...

    A space telescope scheduled for launch in 2007 will be sensitive enough to detect theoretical miniature black holes lurking within our solar system, scientists say. By doing so, it could test an exotic five-dimensional theory of gravity that competes with Albert Einstein's General Theory of Relativity. That is, of course, if the tiny black holes actually exist. The idea, recently detailed online in the journal Physical Review D, is being proposed by Charles Keeton, a physicist at Rutgers University in New Jersey, and Arlie Petters of Duke University in North Carolina.

    There’s no end to it. Gravity appears to be madly greedy and long armed. Members of the Virgo Super cluster are connected to each other, and they’re dozens of millions of light-years apart. Objects in the Pisces-Cetus Super cluster complex are even connected to each other by our invisible and obnoxiously possessive friend. And they are hundreds of millions of light years apart… In fact, you’re so popular that you are gravitationally pulled towards even most distant object in the observable Universe. And they, in turn, are linked to you. As a result, without the outward expansion and acceleration of...

    On March 17, a team of radio astronomers announced they discovered purportedly direct evidence for cosmic inflation—a critical component of the modern Big Bang model. To make this discovery, the researchers used a specialized telescope called BICEP2 located on the Antarctic plateau.1 Radiation that has its strongest intensity in the microwave portion of the electromagnetic spectrum comes to us from all directions in space. Secular researchers interpret this cosmic microwave background radiation (CMB) as "relic radiation" from a time about 400,000 years after the alleged cosmic explosion. Now, a team of astronomers led by John M. Kovac of the Harvard-Smithsonian...

    Physicists are using surprising ideas and mathematical tools originating in string theory to guide research into strange materials that are cropping up in condensed matter laboratories... “Let’s start here,” Sachdev says. “Condensed matter physicists study the behaviour of electrons in many materials – semiconductors, metals, and exotic materials like superconductors.” Normally, these physicists can model the behaviour of a material as if electrons were moving freely around inside it. Even if that’s not what’s actually happening, because of complex interactions, it makes the model easy to understand and the calculations easier to do. Electrons (and occasionally other particles) used in...

    Explanation: In the center of a swirling whirlpool of hot gas is likely a beast that has never been seen directly: a black hole. Studies of the bright light emitted by the swirling gas frequently indicate not only that a black hole is present, but also likely attributes. The gas surrounding GRO J1655-40, for example, has been found to display an unusual flickering at a rate of 450 times a second. Given a previous mass estimate for the central object of seven times the mass of our Sun, the rate of the fast flickering can be explained by a black...

      "Whoever undertakes to set himself up as a judge in the field of truth and knowledge is shipwrecked by the laughter of the Gods." —Albert Einstein  The general, historical dialogue between religion and science goes back a long way—at least to Plato, Aristotle, and Leibniz. Before the 17th century, the goals of science were wisdom, understanding the natural order, and living in harmony with it. Ever since the "quantum revolution" of about 70 years ago, various scientists have been finding the intriguing parallels between their results and certain mystical-transcendental religions. Heisenberg, Bohr, Schroedinger, Eddington, Einstein—all held a mystical, spiritual...

    DRIVING through the countryside south of Hanover, it would be easy to miss the GEO600 experiment. From the outside, it doesn't look much: in the corner of a field stands an assortment of boxy temporary buildings, from which two long trenches emerge, at a right angle to each other, covered with corrugated iron. Underneath the metal sheets, however, lies a detector that stretches for 600 metres. For the past seven years, this German set-up has been looking for gravitational waves - ripples in space-time thrown off by super-dense astronomical objects such as neutron stars and black holes. GEO600 has not...

    The universe is a hologram and everything you can see - including this article and the device you are reading it on - is a mere projection. This is according to a controversial model proposed in 1997 by theoretical physicist Juan Maldacena.Until now the bizarre theory had never been tested, but recent mathematical models suggest that the mind-boggling principle could be true.Professor Maldacena's model suggests that the universe exists in nine dimensions of space and one of time.Now Japanese researchers have attempted to tackle this problem by providing mathematical evidence that the holographic principle might be correct, according to a...

    Researchers focusing on gravitational waves find the first direct evidence for the theory of cosmic inflation, a faster-than-light expansion just after the big bang. Scientists staring at the faint afterglow from the universe's birth 13.8 billion years ago have discovered the first direct evidence for the theory of cosmic inflation — the mysterious and violent expansion after the big bang. The findings, made using radio telescopes at the South Pole, support the idea that our known cosmos make up just a tiny fragment in a much larger, unknown frontier that extends far beyond the reaches of light. During this period...
