Scientists saw a quark plowing through primordial plasma for the first time, offering a rare look at the first moments after ...

What happens when the smallest building blocks of matter refuse to play by the rules of traditional physics? For decades, atomic nuclei have posed a stubborn puzzle: at low energies, they appear as ...

The detection is detailed in a new study published in the journal Physical Review Letters. Immediately following the Big Bang, the universe was an extremely hot, concentrated plasma of elementary ...

It hasn't existed since the beginning of time itself, but now scientists have managed to create what they call quark soup. This substance is believed to be the smallest, hottest, and densest state of ...

I peeked in on the house-sized particle detector known as STAR just after it took its last-ever snapshot of one of the most extreme types of fireball ever created. Inside, the conditions just after ...

Trillions of times smaller than a grain of sand and smaller than an atomic proton or neutron, quarks are among the smallest particles in the universe. They are essentially building blocks for ...

As they probe deeper into the heart of the atom, discovering ever smaller and more mysterious particles and particles within particles, scientists have succeeded in bringing the once stable world of ...
