Ancient neutrinos could put string theory and quantum loop gravity to the test
October 14, 2005Must the Schrodinger's Cat be fat enough for us to detect the possible phenomenon of gravity-driven collapse of the wave-function? In the 1950s, Feynman suggested that the infamous Schrodinger's Cat paradox would be resolved if gravity can be implicated for the collapse of the wave-function.
But, from Feynman in the 1950s to Penrose today, physicists have always taken for granted that one has to look for quantum superpositions of sufficiently macroscopic objects to detect such an effect due to gravity, since only the large mass of such macroscopic objects could distort the very fabric of space-time in accordance with Einstein's theory of gravity, thereby inducing the quantum mechanical wave-function to collapse. In this paper, however, we prove that the idea of Feynman and Penrose can be tested more decisively by observing the skinniest objects in the universe--namely, the tiny neutrinos--provided they have been born just after the Big Bang. In other words, we show that such tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales.

Neutrinos Current Events and Neutrinos News RSSRutgers physicists discover novel electronic properties in two-dimensional carbon structure
Rutgers researchers have discovered novel electronic properties in two-dimensional sheets of carbon atoms called graphene that could one day be the heart of speedy and powerful electronic devices.
Prototype developed to detect dark matter
A team of researchers from the University of Zaragoza (UNIZAR) and the Institut d'Astrophysique Spatiale (IAS, in France) has developed a "scintillating bolometer", a device that the scientists will use in efforts to detect the dark matter of the Universe, and which has been tested at the Canfranc Underground Laboratory in Huesca, Spain.
Invading black holes explain cosmic flashes
Black holes are invading stars, providing a radical explanation to bright flashes in the universe that are one of the biggest mysteries in astronomy today.
To understand the universe, science calls on the ultrasmall
Will the universe expand outward for all of eternity and end in a vast, dark, cold, sterile, diffuse nothingness? Or will the "Big Bang" - the gargantuan explosion that formed the universe 14 billion years ago - end in the "Big Crunch?"
Ytterbium's Broken Symmetry
Ytterbium was discovered in 1878, but until it recently became useful in atomic clocks, the soft metal rarely made the news. Now ytterbium has a new claim to scientific fame.
Precision measurement of W boson mass portends stricter limits for Higgs particle
Scientists of the DZero collaboration at the Department of Energy's Fermi National Accelerator Laboratory have achieved the world's most precise measurement of the mass of the W boson by a single experiment. Combined with other measurements, the reduced uncertainty of the W boson mass will lead to stricter bounds on the mass of the elusive Higgs boson.
Cosmic rays detected deep underground reveal secrets of the upper atmosphere
Cosmic-rays detected half a mile underground in a disused U.S. iron-mine can be used to detect major weather events occurring 20 miles up in the Earth's upper atmosphere, a new study has revealed.
UD researchers focus on building telescope at South Pole
It's 40 degrees F below zero (with the wind chill) at the South Pole today. Yet a research team from the University of Delaware is taking it all in stride.
Einstein's relativity survives neutrino test
Physicists working to disprove "Lorentz invariance" -- Einstein's prediction that matter and massless particles will behave the same no matter how they're turned or how fast they go -- won't get that satisfaction from muon neutrinos, at least for the time being, says a consortium of scientists.
Crystal bells stay silent as physicists look for dark matter
Scientists of the Cryogenic Dark Matter Search experiment today announced that they have regained the lead in the worldwide race to find the particles that make up dark matter. The CDMS experiment, conducted a half-mile underground in a mine in Soudan, Minn., again sets the world's best constraints on the properties of dark matter candidates.

Neutrino Oscillations: Present Status and Future Plans by Jennifer A. Thomas (Author), Patricia L Vahl (Author), Jennifer A. Thomas (Editor), Patricia L. Vahle (Editor) This book reviews the status of a very exciting field -- neutrino oscillations -- at a very important time. The fact that neutrinos have mass has only been proved in the last few years and the acceptance of that fact has opened up a whole new area of study to understand the fundamental parameters of the mixing matrix. The book summarizes the results from all the experiments which have played a role in the measurement of neutrino oscillations and briefly describes the scope of some new planned experiments. Contributions include a theoretical introduction by Stephen Parke from FNAL, as well as articles from all the major experimental groups who have been pivotal in uncovering the nature of the neutrino mass. Contents: Neutrino Oscillation Phenomenology (S J Parke); The... |

The Hotel Child by Ingrid Lucia and The Flying Neutrinos Among the swing revivalists--from the Squirrel Nut Zippers to Royal Crown Revue and Lavay Smith & Her Red Hot Skillet Lickers--no musician can chart his or her pedigree back the way singer Ingrid Lucia and bassist Todd Londagin can. As kids, the story goes, the pair were members of the Flying Neutrinos Family band, living in hotels, playing swing on rafts, and, likely, storing key data for their own Flying Neutrinos. The Hotel Child is the third effort by Lucia, Londagin, guitarist Matt Munisteri, bassist Matt Weiner, and a handful of assorted horns, drums, and accordion. Their music bumps with a sprightly step, buoyed by Lucia's early-Billie Holiday tinged voice and the band's languid looseness. Their brand of swing isn't hyped up with bombastic horn charts or even slicked up like the... |

Physics of Neutrinos by Masataka Fukugita (Author), Tsutomu Yanagida (Author) This book provides a survey of the current state of research into the physics of neutrinos. It is presented in a pedagogical form accessible to non-specialists and graduate students, but will also be useful as a handbook for researchers in this field. The reader finds here a global view of the areas of physics in which neutrinos play important roles, including astrophysics and cosmology. The book is intended to be self-contained: Starting from the standard theory of electroweak interactions, the key notions are explained in detail and the fundamental equations are derived explicitly, so that readers can understand their precise content and implications. Prime emphasis is given to models of massive neutrinos and to the magnetic moment of the neutrino. The first eight chapters deal mostly... |
