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

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.

LUX Dark Matter Detector Finds Nothing Yet

Just three months into its operation, the Large Underground Xenon experiment is already the most sensitive dark matter detector in the world.

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

MIT physicists have proposed a new experiment to look for the elusive dark matter particle known as the 'A Prime' particle.

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

Observational of distant galaxies suggests one of two possibilities: either these galaxies contain significantly more mass than what is seen, or our physical understanding of gravity is flawed.

A superfluid moves like a completely frictionless liquid, seemingly able to propel itself without any hindrance from gravity or surface tension.

An Ultra Secure Optical Communications Network With Temporal Cloaking
2013-06-06 10:07:26

Researchers at Purdue University have demonstrated a temporal cloaking device for optical communications that bends light to create holes in time, something that could have important implications for sending secret messages over fiber optic cables or thwarting would-be eavesdroppers.

Invisibility Cloak For Thermal Flow Constructed By Researchers

By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat.

Blowing Bubbles: The Hunt For Dark Matter Is On At SNOLAB
2013-05-03 05:07:09

A new dark matter experiment is underway in which dark matter particles could potential be directly measured. The experiment, known as COUPP-60, sits a mile and a half underground in Ontario, Canada.

Evidence Of Dark Matter In WIMP Experiment
2013-04-16 09:16:50

An international collaboration of scientists has, for the first time, observed a concrete hint of a WIMP – weakly interacting massive particle – which physicists believe could be behind the mysterious phenomenon of dark matter.

Black Holes: Getting Around The Firewall Paradox
2013-03-07 04:37:54

Black holes are incredibly difficult objects to understand, partially because their very existence seemingly challenges the physical laws of the Universe. Because of their extreme nature, various peculiarities arise that give scientists pause.

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...
