New picture of atomic nucleus emerges
(PhysOrg.com) -- When most of us think of an atom, we think of tiny electrons whizzing around a stationary, dense nucleus composed of protons and neutrons, collectively known as nucleons. A collaboration between ...
In the early universe, rapid expansion or something very weird
(PhysOrg.com) -- The widely-accepted theory of cosmic inflation states that our universe expanded rapidly in the moments after its birth, resulting in the immense expanse we see today.
Hitches emerge as culprit in 'faster-than-light' particle (Update)
Scientists who last year found particles that appeared to break the Universe's speed limit are looking at two technical issues that could have skewed the controversial finding, CERN said Thursday.
Faster than light neutrinos? More like faulty wiring
You can shelf your designs for a warp drive engine (for now) and put the DeLorean back in the garage; it turns out neutrinos may not have broken any cosmic speed limits after all.
Chandra finds fastest wind from stellar-mass black hole
Astronomers using NASA's Chandra X-ray Observatory have clocked the fastest wind yet discovered blowing off a disk around a stellar-mass black hole. This result has important implications for understanding ...
Physicists develop theoretical framework for interpreting results of subatomic-particle collisions
Accelerating subatomic particles to almost the speed of light and then crashing them together reveals much about the nature of the matter. Nuclear physicists need to fully understand these complex collisions ...
Through hardship to the stars
"Humanity's adventurous, stubborn, mad and glorious aspiration to reach the stars" is the subject of Physics World's lead feature in January.
Physicist creates scale model of LHC ATLAS experiment of out LEGO blocks
'Faster-than-light' particles spark science drama
Oh Albert. Did you get it wrong? In 2011, physics was shaken by an experiment which said the Universe's speed limit, enshrined by Einstein in his 1905 theory of special relativity, could be broken.
Earth's outer core deprived of oxygen: study
The composition of the Earth's core remains a mystery. Scientists know that the liquid outer core consists mainly of iron, but it is believed that small amounts of some other elements are present as well. Oxygen ...
Cosmic particle accelerators get things going
(PhysOrg.com) -- ESA's Cluster satellites have discovered that cosmic particle accelerators are more efficient than previously thought. The discovery has revealed the initial stages of acceleration for the ...
The secrets of tunneling through energy barriers
Electrons moving in graphene behave in an unusual way, as demonstrated by 2010 Nobel Prize laureates for physics Andre Geim and Konstantin Novoselov, who performed transport experiments on this one-carbon-atom-thick material. ...
Scientists take fresh look at 'faster-than-light' experiment
Scientists who threw down the gauntlet to physics by reporting particles that broke the Universe's speed limit said on Friday they were revisiting their contested experiment.
