Photon
A photon is an elementary particle, the quantum of light and all other forms of electromagnetic radiation. It is the force carrier for the electromagnetic force, even when static via virtual photons. ...

Quantum "Weeping Angel" Effect Freezes Atoms In Place
The paradox of Schroedinger’s Cat famously demonstrates that a quantum cat sealed in a box is both alive and dead at the same time until we look inside, at which point it becomes one or the other. Suc...
Direct measurements of the wave nature of matter
New experimental techniques map out wave properties only known previously from theory.
Reality Doesn’t Exist Until We Measure It, Quantum Experiment Confirms
Australian scientists have recreated a famous experiment and confirmed quantum physics's bizarre predictions about the nature of reality, by proving that reality doesn't actually exist until we measur...
FIRST OBJECT TELEPORTED FROM EARTH TO ORBIT!
✔Researchers in China have teleported a photon from the ground to a satellite orbiting more than 500 kilometers above.
A New ‘Einstein’ Equation Suggests Wormholes Hold Key To Quantum Gravity
A new Einsteinian equation, ER=EPR, may be the clue physicists need to merge quantum mechanics with general relativity.
Elusive Dark Matter Galaxy Revealed By Cosmic Lens
An invisible dark-matter galaxy hides in the edges of another larger galaxy serving as a natural magnifying glass. Astronomers probing the sky used the gravity of a massive galaxy as a natural magnif...
Earth's Core Is Two-And-A-Half Years Younger Than Its Crust
We have long known that gravity makes the Earth's centre age more slowly than its surface – but the effect is much more pronounced than once thought
Three 'Twisted' Photons In 3 Dimensions
Researchers at the Institute of Quantum Optics and Quantum Information, the University of Vienna, and the Universitat Autonoma de Barcelona have achieved a new milestone in quantum physics: they were ...
Gravitational Wave Detection Might Be Announced Feb. 11
Gravitational waves may have been detected for the first time, but we won't know for sure until February 11, 2016 — when scientists will either confirm or dispel the rumors, sources close to the matte...
After 100 Years, Scientists Are Finally Closing In On Einstein’s Ripples
The rain began to fall as Joe Giaime and I scrambled down a lonely rise, back toward the observatory’s main building. It wasn’t so much rain as a hard mist, characteristic of the muggy weather souther...
How Copper Makes Organic Light-Emitting Diodes More Efficient
Use of copper as a fluorescent material allows for the manufacture of inexpensive and environmentally compatible organic light-emitting diodes (OLEDs). Thermally activated delayed fuorescence (TADF) e...
Making Astronomical Observations In The Laboratory- Researchers Investigate How Light Behaves In Curved Space
To investigate the influence of gravity on the propagation of light, researchers usually have to examine astronomical length scales and huge masses. However, physicists at Friedrich-Alexander-Universi...
Scientists Struggle To Stay Grounded After Possible Gravitational Wave Signal
Not for the first time, the world of physics is abuzz with rumours that gravitational waves have been detected by scientists in the US. Lawrence Krauss, a cosmologist at Arizona State university, twee...
Special relativity
In physics, special relativity (SR, also known as the special theory of relativity or STR) is the generally accepted physical theory regarding the relationship between space and time. It is based on t...

Wave-particle duality
Wave–particle duality is the concept that every elementary particle or quantic entity exhibits the properties of not only particles, but also waves. It addresses the inability of the classical concep...
Bose gas
An ideal Bose gas is a quantum-mechanical version of a classical ideal gas. It is composed of bosons, which have an integer value of spin, and obey Bose–Einstein statistics. The statistical mechanics ...

In physics, a spin network is a type of diagram which can be used to represent states and interactions between particles and fields in quantum mechanics. From a mathematical perspective, the diagrams ...
MOA-2008-BLG-310L
MOA-2008-BLG-310L is a 23rd magnitude star located at least 20000 light years away in the constellation Scorpius. This star has mass 0.67 solar masses which imply that it could probably be a late K-ty...
Graviphoton
In theoretical physics, a graviphoton (aka gravivector) is a hypothetical particle which emerges as an excitation of the metric tensor (i.e. gravitational field) in spacetime dimensions higher than fo...
