Flavor Changing Neutrinos

John P. Millis, PhD for redOrbit.com - Your Universe Online Protons, neutrons, and electrons – it is these tiny particles that make up most of the normal matter (that is, non-dark matter) in the Universe. Yet it is another, nearly massless particle that may turn out to be the most revealing about the nature of the cosmos. The neutrino plays a crucial role in nuclear processes such as fusion. But because of its small mass and neutral charge, it is very difficult to measure and study...

Mexico Observatory To Hunt For Gamma Rays In Known Universe
2013-08-22 07:35:15

April Flowers for redOrbit.com - Your Universe Online A new observatory has begun formal operations in Mexico. The High-Altitude Water Cherenkov (HAWC) Gamma Ray Observatory is designed to study the origins of very high-energy cosmic rays and observe the most energetic objects in the known universe. The HAWC uses a unique detection technique that is different from the classical astronomical design of mirrors, lenses, and antennae, making the extraordinary observatory a significant boost...

Door Opened For Solid State Physics By Berlin Researchers

Helmholtz Association Laser processes observed with X-rays on a solid Without the currently available plethora of X-ray methods, basic research in the physical sciences would be unthinkable. The methods are used in solid state physics, in the analysis of biological structures, and even art historians have X-rays to thank for many new insights. Now, scientists at the Helmholtz Center Berlin (HZB) have identified yet another area of application. The team around Dr. Martin Beye and Prof....

Higgs Boson Dark Energy
2013-08-12 08:44:59

John P. Millis, PhD for redOrbit.com - Your Universe Online For the better part of two decades, the greatest fundamental question facing physics and cosmology has been, quite simply, what is dark energy? Detailed observations of galaxies in our Universe reveal the expansion of the Universe is accelerating. Even after accounting for all of the normal matter, radiation, and even the theorized dark matter out there, there still simply isn't enough "stuff" to explain the dynamics of the...

Physicists use dysprosium to put bounds on maximum speed of electrons Albert Einstein's assertion that there's an ultimate speed limit – the speed of light – has withstood countless tests over the past 100 years, but that didn't stop University of California, Berkeley, postdoc Michael Hohensee and graduate student Nathan Leefer from checking whether some particles break this law. The team's first attempt to test this fundamental tenet of the special...

Fermilab Receives “Rock Star” Electromagnet
2013-07-28 08:41:07

redOrbit Staff & Wire Reports - Your Universe Online The 50-foot-wide, 15-ton electromagnet, which became a national sensation during its move from New York to the Chicago area, has reached its final destination at the Fermi National Accelerator Laboratory (Fermilab), according to various media reports. The massive magnet, which will be used by Fermilab officials to study lightning-quick particles, traveled more than 3,000 miles over land and sea and received "a rock star's...

New novel aims to get teens interested in science through science fiction and old fashioned adventure. NEW YORK, N. Y. (PRWEB) July 22, 2013 “The Higgs Boson is forgotten,” grumbled author Michael Raymond. “The biggest scientific discovery in a generation, and many people haven’t even heard of it.” CERN, the organization that discovered the Higgs Boson has since moved on to researching dark matter, another substance largely unfamiliar to the public. The author hopes to change...

International research including the UK and Japan has confirmed that subatomic particles called neutrinos have a new form of identity-shifting property. Announced today (19 July 2013) these results could one day help scientists explain why the universe contains matter but very little antimatter. The findings are further confirmation from the T2K neutrino experiment in Japan of neutrinos changing between different types, or oscillating, in a new way. Dr Alfons Weber, Professor of Physics...

GERDA sets new limits on extremely rare decay Neutrinos are the most elusive particles having extremely weak interactions with all other particles. They have rather unusual properties and are even expected to be identical with their own antiparticles. So far this property is, however, not experimentally verified even though many studies of neutrinos over the last 60 years have already boosted our understanding of elementary particle physics. Now scientists of the GERDA collaboration...

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Physics is the scientific study of matter and its motion through space/time and its derivitives, including energy and force. It is generally the analysis of nature and is conducted to help us understand how the universe behaves. Physics comes from the Greek word physis, meaning "nature". It is among the oldest academic disciplines, and perhaps the oldest pertaining to astronomy. Physics has been considered synonymous with philosophy, chemistry, mathematics, and biology for more than 2000...

WIMP -- In astronomy, WIMPs, or weakly interacting massive particles, figure into one explanation of the dark matter problem. The particles are called "weakly interacting" because they seem not to have much interaction with normal matter (electrons, protons, and neutrons) other than gravitational attraction (thus "massive"). Assuming that there are Weakly Interacting Massive Particles, these particles would then fall out of equilibrium with the universe when they are non-relativistic....

Strange Matter -- Strange matter (also known as quark matter) is an ultra-dense phase of matter that is theorized to form inside particularly massive neutron stars (which are then known as "strange stars" or "quark stars"). It's theorized that when neutronium is put under sufficient pressure due to the gravitation of a large neutron star, the individual neutrons break down and their constituent quarks form strange matter. Strange matter is composed of strange quarks bound to each...

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...

'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
