Latest Theoretical physics Stories
Dark matter research, like all experiments involving particle and astrophysical detections, relies on sorting out the desired events (the source events) from the noise (the background events). Since the interactions occur at a quantum level, the statistical process of sorting through the data is laborious, but also, more importantly, relies on your ability to calibrate and understand the instrument.
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.
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.
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.
A group of researchers from Imperial College London have created a means by which certain theoretical models can be visualized using a 3D printer.
Albeit with much controversy, physicists are using ancient lead ingots from sunken ships in the study of dark matter in neutrinos. Archaeologists have gone on the offensive, expressing concerns over the destruction of underwater cultural heritage.
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.
A research team is hunting for a theorized but never-before-seen elementary particle called an axion that may be at the heart of dark matter.
Just three months into its operation, the Large Underground Xenon experiment is already the most sensitive dark matter detector in the world.
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...
