Latest Theoretical physics Stories
Attempts to build a Harry Potter-style cloak of invisibility have come and gone, but the inventors of The Rochester Cloak continue to hone their craft, and this week released new video footage of what they are calling the world’s first known 3D continuous multidirectional cloaking device.
Researchers from the University of Nevada, Reno and the University of Victoria have found a new use for the Global Positioning System — the direct detection and measuring of dark matter.
For thirty long years, the scientific community has been searching for evidence that dark matter is comprised of exotic particles. A new study from Case Western Reserve University, however, suggests that researchers are looking in entirely the wrong direction.
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.
A new study describes the detection of a curious signal in the X-ray sky which may prove the axion particle really exists. The findings also provide tantalizing insight into the nature of dark matter.
Researchers from the University of Rochester in New York have developed an inexpensive new way to create a Harry Potter-esque invisibility cloak using ordinary lenses to obscure objects from sight at a variety of angles.
A unique experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory (Fermilab) will look at the very structure of our universe and answer some big questions - including whether we live inside a 2-D hologram.
The new PandaX facility, located deep underground in the southwestern Chinese province of Sichuan, hosts a large liquid-xenon detector designed to search for direct evidence of dark matter interactions with the nuclei of xenon and to observe 136Xe double-beta decay.
From the physics labs at Yale University to the bottom of a played-out gold mine in South Dakota, a new generation of dark matter experiments is ready to commence.
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...
