The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...

Physicists recreated the first millisecond after the Big Bang — and found it was surprisingly soupy
Scientists saw a quark plowing through primordial plasma for the first time, offering a rare look at the first moments after ...
In the first fraction of a second after the big bang, the universe was a hot, dense ocean of perfectly free-flowing particles called a quark-gluon plasma. It didn't last long—all the gluons and ...
Researchers have been working for decades to understand the architecture of the subatomic world. One of the knottier questions has been where the proton gets its intrinsic angular momentum, otherwise ...
LAWRENCE -- A team of high-energy nuclear experimental particle physicists from the University of Kansas has earned a two-year, $400,000 Department of Energy (DoE) grant to investigate strong ...
James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...
Researchers at Brookhaven National Laboratory's RHIC particle accelerator have determined that an exotic form of matter produced in their collisions is the most rapidly spinning material ever detected ...

The US.'s only particle collider recreated moments from the early universe. Now, it has closed—to make way for a new instrument
For a mere moment after the Big Bang, no neutrons or protons are thought to have existed. These neutral and positively charged particles, respectively, make up the center of all atoms today. But ...
Comparing the number of direct photons emitted when proton spins point in opposite directions (top) with the number emitted when protons collide head-to-tail (bottom) revealed that gluon spins align ...
All the matter we know of in the Universe is made up of Standard Model particles. Photons and neutrinos zip through the Universe all the time, far outnumbering all the other particles. Normal, ...
For the first time, by studying quantum correlations between triplets of secondary particles created during high-energy collisions in the LHC accelerator, it has been possible to observe their ...
The early Universe was a strange place. The Universe was so dense and hot that atoms and nuclei could not form—they would be ripped apart by high-energy collisions. Even protons and neutrons could not ...
