    Two physicists are trying to revive one of the great debates of twentieth-century science, arguing that the Big Bang may never have happened. Their work presents a radically different vision of the universe from the one cosmologists now work with. "The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there," says Dr. Ahmed Farag Ali of Benha University, Egypt. In collaboration with Professor Saurya Das of the University of Lethbridge, Canada, Ali has created a series of equations that describe a universe much like Hoyle's; one without a...

    Astronomers have discovered the largest and most luminous black hole ever seen — an ancient monster with a mass about 12 billion times that of the sun — that dates back to when the universe was less than 1 billion years old. It remains a mystery how black holes could have grown so huge in such a relatively brief time after the dawn of the universe, researchers say.

    Overall, the consensus among the panelists: the LHC’s second run will produce more data to refine the Standard Model—the theory that describes subatomic particles and the forces that dictate their behavior. This refinement is needed, said Heinemann, because there are still fundamental physics questions the Standard Model can’t address. Questions remain about gravity (Why is it so weak?); antimatter (Why is there so little of it?); and dark matter, the mysterious and invisible substance that makes up nearly a quarter of the universe (What particle might be responsible?).

    Hypervelocity stars have been observed traversing the Galaxy at extreme velocities (700 km/s), but the mechanisms that give rise to such phenomena are still debated. Astronomer Thomas M. Tauris argues that lopsided supernova explosions can eject lower-mass Solar stars from the Galaxy at speeds up to 1280 km/s. “[This mechanism] can account for the majority (if not all) of the detected G/K-dwarf hypervelocity candidates,” he said. Several mechanisms have been proposed as the source for hypervelocity stars, and the hypotheses can vary as a function of stellar type. A simplified summary of the hypothesis Tauris favors begins with a higher-mass...

Researchers say clocks with this level of accuracy could open up new areas of science by allowing tiny changes fluctuations in the strength of gravity to be measured.

    Thanks to Einstein’s theory of special relativity, we can all agree that the speed of light is constant for all observers. We can also agree that, if you’re not a photon, approaching light speed comes with some pretty funky rules – namely, anyone watching you will see your length compress and your watch slow down. But the slowing of time also occurs near gravitationally potent objects, which are described by general relativity. So if you happen to be sight-seeing in the center of the Milky Way and you make the regrettable decision to get too close to our supermassive black...

    Nuclear fusion is the dream of energy scientists the world over, because it promises limitless, clean electricity. Most efforts to kickstart the process use high-intensity lasers, insane magnetic field and super-hot hydrogen plasmas. But there may be a more humble alternative. It's called sonofusion, and it involves bubbles.Nuclear fusion is the process through which the cores of atoms, called nuclei, collide to form a new, larger atomic nucleus. When the two nuclei are of a lower mass than iron, the reaction creates energy—lots and lots of energy. For instance, when two hydrogen nuclei smash into each other, they creating...

That idea had been widely believed, but researchers had hoped to bolster it by finding a particular trait in light left over from the very early universe. That signal is what the researchers claimed they...

    A pulsar, one of deep space’s spinning “lighthouses”, has faded from view because a warp in space-time tilted its beams away from Earth. The tiny, heavy pulsar is locked in a fiercely tight orbit with another star. The gravity between them is so extreme that it is thought to emit waves and to bend space - making the pulsar wobble. By tracking its motion closely for five years, astronomers determined the pulsar’s weight and also quantified the gravitational disturbance. Then, the pulsar vanished. Its wheeling beams of radio waves now pass us by, and the researchers have calculated that this...

    The idea underlying string unification is as simple as it is seductive. Since the early 20th century, nature’s fundamental constituents have been modeled as indivisible particles—the most familiar being electrons, quarks and neutrinos—that can be pictured as infinitesimal dots devoid of internal machinery. String theory challenges this by proposing that at the heart of every particle is a tiny, vibrating string-like filament. And, according to the theory, the differences between one particle and another—their masses, electric charges and, more esoterically, their spin and nuclear properties—all arise from differences in how their internal strings vibrate. Much as the sonorous tones of...

    A new record-breaking atomic clock is so precise it neither loses nor gains a second in five billion years - longer than the age of the Earth. The 'strontium lattice clock' is 50% more accurate than the previous record holder, the National Institute of Standards and Technology (NIST) quantum logic clock. Researchers say the clock is so accurate, it can even reveal the effect gravity has on time.

Merten (Heidelberg/Bologna) If redshift equals distance calculations are incorrect, the Universe could be a much different looking place. “Of course, if one ignores contradictory observations, one can claim to have an ‘elegant’ or ‘robust’ theory. But it isn’t science.” — Halton Arp The speed of light is used as a benchmark for defining cosmological distance calculations. As discussed in past Picture of the Day articles, the shifting of Fraunhofer lines into the red end of electromagnetic spectra is...

    Measurements indicate that this nebula is one degree above absolute zero. Temperature has little to do with electricity, though. “Bipolar outflow” is a term used to describe the nebular structure seen above, although the cause of the effect remains baffling to scientists who study such phenomena. One theory is that its shape is due to slow-moving stellar material interfering with dust and gas that was ejected from a red giant star at higher velocities. Magnetic fields are sometimes invoked to describe lobate celestial objects, but the electric current flow needed for their generation is neglected. Astronomical theories do not...

    Could TARS From ‘Interstellar’ Actually Exist? We Asked Science A robotics expert breaks down TARS. by Shaunna Murphy 15 hours ago Apologies to Matthew McConaughey, but the real, breakout star of “Interstellar” was clearly TARS the sarcastic space robot (voiced by Bill Irwin). A former marine companion bot with angular limbs and acerbic wit, director Christopher Nolan somehow made TARS (and his sister robot, CASE) one of the most fully-formed, anthropomorphized robots in film history — without even giving him a face. “I wanted a more realistic approach to what a robot would be,” Nolan told the Associated Press. “I...

    Two USC researchers have proposed a link between string field theory and quantum mechanics that could open the door to using string field theory—or a broader version of it, called M-theory—as the basis of all physics. "This could solve the mystery of where quantum mechanics comes from," said Itzhak Bars, USC Dornsife College of Letters, Arts and Sciences professor and lead author of the paper. Bars collaborated with Dmitry Rychkov, his Ph.D. student at USC. The paper was published online on Oct. 27 by the journal Physics Letters. Rather than use quantum mechanics to validate string field theory, the researchers...

    Last year CERN announced the finding of a new elementary particle, the Higgs particle. But maybe it wasn't the Higgs particle, maybe it just looks like it. And maybe it is not alone. Many calculations indicate that the particle discovered last year in the CERN particle accelerator was indeed the famous Higgs particle. Physicists agree that the CERN experiments did find a new particle that had never been seen before, but according to an international research team, there is no conclusive evidence that the particle was indeed the Higgs particle... "The CERN data is generally taken as evidence that the...
  • Physicists Resurrect an Old, ‘Strange’ Dark Matter Theory

    Physicists Resurrect an Old, ‘Strange’ Dark Matter Theory Written by Michael Byrne Editor November 5, 2014 // 09:15 AM EST Dark matter might not be nearly as exotic as most theories about the stuff suggest. Instead, it could be macroscopic clumps of material formed from common particles already found within the Standard Model of particle physics. This argument comes courtesy of physicists at Case Western University, as presented in a new paper posted to the arXiv pre-print server. Dark matter is usually thought of in terms of exotic, so-far undiscovered particles. The leading candidates are known as weakly interacting massive particles,...

    Imagine if you were told that the world is simple and exactly as it seems, but that there is an infinite number of worlds just like ours. They share the same space and time, and interact with each other. These worlds behave as Newton first envisioned, except that the slightest interactions of the infinite number create nuances and deviations from the Newtonian mechanics. What could be deterministic is swayed by many worlds to become the unpredictable. Schrödinger, in explaining his wave function and the interaction of two particles (EPR paradox) coined the term “entanglement”. In effect, the MIW theory is...

    If modern physics is to be believed, we shouldn’t be here. The meager dose of energy infusing empty space, which at higher levels would rip the cosmos apart, is a trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion times tinier than theory predicts. And the minuscule mass of the Higgs boson, whose relative smallness allows big structures such as galaxies and humans to form, falls roughly 100 quadrillion times short of expectations. Dialing up either of these constants even a little would render the universe unlivable. To account for our incredible luck, leading cosmologists like Alan Guth and...

    Photons generally do not interact with each other in free space but instead one passes through the other with no effect to either one. Vienna University of Technology researchers have made a significant and groundbreaking discovery in the field of quantum mechanics. A team of researchers has developed some unique hardware, which enable photons to interact. This hardware is composed of micro-thin fiber made of glass, which in turn attached to a device called a resonator. The photon particle light can enter the resonator, moves in a circular fashion and then returns to the glass fiber. This change in pathways...

    A chunk of copper became the coldest cubic meter (35.3 cubic feet) on Earth when researchers chilled it to 6 millikelvins, or six-thousandths of a degree above absolute zero (0 Kelvin). This is the closest a substance of this mass and volume has ever come to absolute zero. Researchers put the 880-lb. (400 kilograms) copper cube inside a container called a cryostat that is specially designed to keep items extremely cold. This is the first cryostat built that is capable of keeping substances so close to absolute zero.
