    Shear mixing could be used to produce graphene flakes in bulk © CRANN Suspensions of high quality graphene can be produced quickly and cheaply using a common industrial mixer, researchers in Ireland have discovered.1 The scientists even managed to produce small amounts of graphene using a kitchen blender.While next generation electronic devices need ultra-pure, monolayer graphene produced by mechanical exfoliation or chemical vapour deposition, everyday electronics such as batteries and solar cells are produced using solution coating. Therefore, to use graphene in these kinds of electronics engineers require huge amounts of high quality graphene flakes suspended in solution.In 2008, Jonathan...

    In a new national poll on America's scientific acumen, more than half of respondents said they were "not too confident" or "not at all confident" that "the universe began 13.8 billion years ago with a big bang." The poll was conducted by GfK Public Affairs & Corporate Communications. Scientists were apparently dismayed by this news, which arrives only a few weeks after astrophysicists located the first hard evidence of cosmic inflation. But when compared to results from other science knowledge surveys, 51 percent isn't too shameful -- or surprising. Other polls on America's scientific beliefs have arrived at similar findings....

    A team of nearly 100 physicists from around the world have achieved results verifying that the elementary particle known as the neutrino exhibits a distinctive pattern of oscillation. This discovery shows that it is likely that the Standard Model, proposed in the 1970s to describe the fundamental forces and particles that make up all matter, is incomplete. 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.

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.

    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.

    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...

Such an inflationary epoch has been postulated to explain several puzzling cosmic attributes such as why our universe looks similar in opposite directions. Yesterday, results were released showing an expected signal of unexpected strength, bolstering a prediction of inflation that specific patterns of polarization should exist in cosmic microwave background radiation -- light emitted 13.8 billion years ago as the universe first became transparent. Called B-mode polarizations, these early swirling patterns can be directly attributed to squeeze and stretch effects that gravitational radiation has on photon-emitting electrons. The...

Such a quantum view would allow for seemingly counterintuitive phenomena such as entanglement, in which the measurement of one particle instantly affects another, even if those entangled particles are at opposite ends of the universe.

    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...

    South Pole Telescope scientists have detected for the first time a subtle distortion in the oldest light in the universe, which may help reveal secrets about the earliest moments in the universe's formation. The scientists observed twisting patterns in the polarization of the cosmic microwave background -- light that last interacted with matter very early in the history of the universe, less than 400,000 years after the big bang. These patterns, known as "B modes," are caused by gravitational lensing, a phenomenon that occurs when the trajectory of light is bent by massive objects, much like a lens focuses light.

    Almost a century ago, renowned quantum theorist Werner Heisenberg found fundamental limits on how well a quantum system can be prepared and measured, known as Heisenberg's uncertainty principle. However, only the limit that pertains to the preparation of quantum systems has been quantified; the other two, relating to measurements, have long been a matter of debate, lacking a formal treatment. These limits are: That it is impossible to jointly measure incompatible quantities, for instance, location and speed of a quantum object, with perfect accuracy; and that a measurement of one of these quantities necessarily disturbs the other.

    To think that our universe is 13.8 billion years old is incredible enough. But now researchers are proposing that the universe stretches back into time infinitely with no singular point where it started. The idea is one possible result of something known as ‘rainbow gravity’- a theory that is not widely accepted among physicists, though many say the idea is interesting. The theory’s name comes from a suggestion that gravity's effect on the cosmos is felt differently by varying wavelengths of light, which can be found in the colours of the rainbow. The theory was proposed 10 years ago in...

    There’s a web post from the Nature website going around entitled “Simulations back up theory that Universe is a hologram.” It’s an interesting concept, but suffice it to say, the universe is not a hologram, certainly not in the way people think of holograms. So what is this “holographic universe” thing? ... From this you get a headline implying that we live in a hologram. On twitter, Ethan Siegel proposed a more sensible headline: “Important idea of string theory shown not to be mathematically inconsistent in one particular way”.

    The universe could be about to collapse, and everything in it—including us—will be compressed into a small, hard ball. The process may already have started somewhere in our cosmos and is eating away at the rest of the universe, according to theoretical physicists. The mind-bending concept has been around for a while, but now researchers in Denmark claim they have proven it is possible with mathematical equations. …

    High-temperature superconductors exhibit a frustratingly varied catalog of odd behavior, such as electrons that arrange themselves into stripes or refuse to arrange themselves symmetrically around atoms. Now two physicists propose that such behaviors – and superconductivity itself – can all be traced to a single starting point, and they explain why there are so many variations. This theory might be a step toward new, higher-temperature superconductors that would revolutionize electrical engineering with more efficient motors and generators and lossless power transmission. -snip- Most subatomic particles have a tiny magnetic field – a property physicists call "spin" – and electrical resistance...

    Sherwyn Sarabi scored an IQ of 160, just like Albert Einstein, Bill Gates, and Stephen Hawking. The British boy is already studying at the level of a 9-year-old and has read over 190 books. A four-year-old boy has stunned psychologists—after intelligence tests revealed him to have the same IQ as Einstein. Sherwyn Sarabi has tested off the scale for intelligence—scoring an IQ of 160—the highest mark on the test. It's the same score that experts believe scientist Einstein had, as well as being identical to that of Bill Gates and Stephen Hawking. Sherwyn from Barnsley, Yorks, started school two years...

    The problem is that our understanding of both particle physics and the geometry of gravity is incomplete. “Having gone from basically philosophical understandings of why things fall to mathematical descriptions of how things accelerate down inclines from Galileo, to Kepler’s equations describing planetary motion to Newton’s formulation of the Laws of Physics, to Einstein’s formulations of relativity, we’ve been building and building a more comprehensive view of gravity. But we’re still not complete,” said Dr. Pamela Gay. “We know that there still needs to be some way to unite quantum mechanics and gravity and actually be able to write down...

    Sonner then set about to create quarks to see if he could watch what happens when two are entangled with each other. Using an electric field, he was able to catch pairs of particles coming out of a vacuum environment with a few “transient” particles in it. - Once he caught the particles, he mapped them in terms of space-time (four-dimensional space). Note: gravity is believed to be the fifth dimension because it can bend space-time [5th Dimension?], as you can see in these images of galaxies below. - Sonner then tried to figure out what would happen in the...

    Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived. Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another. But here’s the catch: One couldn’t actually travel, or even communicate, through these wormholes, said Andreas Karch, a UW physics professor. Quantum entanglement occurs when a pair or a...
