With the emergence of metamaterials and transformation optics in the past few years, invisibility has become a scientific possibility that has attracted sustainable research interest. Recently, a review paper, entitled "Invisibility cloak from forward design to inverse design", published in SCIENCE CHINA Information Sciences, 2013, Vol. 56, reviewed design methodologies and experimental developments of the invisibility cloak from a practical perspective. The recent transition from a forward...

Pixidis researcher Tom Whitney of Minneapolis has achieved the Holy Grail quest of modern physical science: the discovery of Einstein's famed unified field equation. Sought by thousands of scientists around the world, this equation reveals the ultimate blueprint running the universe. Minneapolis, MN (PRWEB) January 03, 2014 The unified field equation theorized to exist by Einstein has been discovered—uniting hundreds of years of multidisciplinary science in a single, historic fell...

Battery-Powered Cloaking Device In The Works At U Texas
2013-12-19 08:09:17

Gerard LeBlond for redorbit.com - Your Universe Online The first battery-powered cloaking device is being designed by researchers at the University of Texas. The use of an external source of power will greatly expand its bandwidth of operation. Andrea Alu is the associate professor in the Department of Electrical and Computer Engineering at the Cockrell School of Engineering in Austin, Texas. He and his team have proposed the design of a cloaking device (active cloak) powered by a...

John P. Millis, PhD for redOrbit.com - Your Universe Online In my 'Introduction to Astronomy' course, I am often faced with a challenge: Many of the theoretical models that we have created to explain the Universe around us are quite difficult to visualize. This is sometimes particularly difficult for those not studying in a scientific field, but I even find myself struggling under the weight of mathematical constructs where the connection to reality is opaque at best. Humans, in...

Lead Ingots From Shipwrecks Being Used To Hunt For Dark Matter
2013-12-02 08:18:12

Gerard LeBlond for redorbit.com - Your Universe Online A Roman vessel carrying ingots of lead, which was removed from the Sierra of Cartagena, sank more than two thousand years ago off the coast of Sardinia. Now, more than a hundred of these lead bricks have been used to build the ‘Cryogenic Underground Observatory for Rare Events’ (CUORE), an advanced detector of almost weightless subatomic particles (neutrinos) and is located at the Gran Sasso National Laboratory in Italy....

Quest For ‘Invisibility Cloak’ Remains Elusive, It So Appears
2013-11-12 07:43:18

redOrbit Staff & Wire Reports - Your Universe Online Limitations in current cloaking technology allow objects to be temporarily concealed at only narrow wavelengths of light or microwaves, while many newer designs actually make things more visible, experts at the University of Texas acknowledged on Monday. Current cloaking devices, which are made of a variety of materials such as planes of glass, work by bending light around objects to make them temporarily invisible. Scientists...

Axion Search For Dark Matter
2013-11-07 08:36:41

April Flowers for redOrbit.com - Your Universe Online A research team at the University of Washington, led by Professor Leslie Rosenberg, is hunting for a theorized but never-before-seen elementary particle called an axion. The researchers will use the recently retooled, extremely sensitive detector that is currently in a testing and shakeout phase at UW's Center for Experimental Nuclear Physics Astrophysics. Physicists in the late 1970s first hypothesized the axion as a solution to a...

LUX Dark Matter Detector Finds Nothing Yet
2013-10-30 13:49:42

Brett Smith for redOrbit.com - Your Universe Online Just three months into its operation the Large Underground Xenon (LUX) experiment is already the most sensitive dark matter detector in the world, according to scientists from Brown University. “LUX is blazing the path to illuminating the nature of dark matter,” said Rick Gaitskell, professor of physics at Brown University and project spokesperson. The detector sits over a mile below the Sanford Underground Research Facility in...

Experiment Looks For Dark Matter Particle
2013-10-29 08:16:46

John P. Millis, PhD for redOrbit.com - Your Universe Online As we peer into the darkness of space we find stars, planets, nebulae, and gas clouds. These objects are all made of normal matter – protons, neutrons, electrons, and other elementary particles. But it is the matter that we don’t see that has confounded astronomers for decades. An estimated 80 percent of the stuff that makes up the Universe does not interact electromagnetically. This aptly named dark matter is...

Modified Gravity Theory Predicts Galaxy Dynamics
2013-08-29 10:22:45

John P. Millis, PhD for redOrbit.com - Your Universe Online For decades astronomers have studied the motions of galaxies – their rotations about their axes, as well as their interactions with each other – and been puzzled by what they have observed. The data suggests one of two possibilities: either these galaxies, and the space between them, contain significantly more mass than what is seen, or our physical understanding of gravity is flawed. The oft-discussed solution is that...

Classical and Quantum Gravity
2012-05-12 20:18:16

Classical and Quantum Gravity is a peer-reviewed journal published by IOP Science. As of May 2012, the editor-in-chief is Clifford M Will (Washington University, St. Louis). The journal covers all aspects of gravitational physics and the theory of space-time. It scope includes: Classical general relativity, Applications of relativity, Experimental gravitation, Cosmology and the early universe, Quantum gravity, Supergravity, superstrings and supersymmetry, and Mathematical physics relevant...

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...

String Theory -- A string theory is a physical model whose fundamental building blocks are extended objects (strings, membranes and higher-dimensional objects) rather than points. String theories are able to avoid problems, such as infinite energy density, associated with the presence of mathematical points in a physical theory. The term 'string theory' properly refers to both the 26 dimensional bosonic string theories and to the 10 dimensional superstring theories discovered by...

Spacetime -- In special relativity and general relativity, time and three-dimensional space are treated together as a single four-dimensional manifold called spacetime (alternatively, space-time; see below). A point in spacetime may be referred to as an event. Each event has four coordinates (t, x, y, z). Just as the x, y, z coordinates of a point depend on the axes one is using, so distances and time intervals, invariant in Newtonian physics, may depend on the reference frame of an...
