Colliding heavy atomic nuclei together creates a fluidlike soup of visible matter's fundamental building blocks, quarks and gluons. This soup has very low viscosity—a measure of its "stickiness," or resistance to flow.

Scientists can use powerful colliders to smash atomic nuclei together to create a quark-gluon plasma (QGP). This "soup" of quarks and gluons, some of the fundamental building blocks of matter, filled the early universe. Tracking ...

To study atomic nuclei and subatomic particles, scientists use the Large Hadron Collider (LHC) to collide heavy ions—atomic nuclei completely stripped of their surrounding electrons. In these collisions, the quarks and ...

It may be hard to imagine that the debris of violent heavy ion collisions—which dissolve the boundaries of protons and neutrons and produce thousands of new particles—can be used to gain detailed insight into the properties ...

The action of neutrinos in supernovae is poorly understood. When the core of a massive star at the end of its life collapses on itself under the effect of gravity, the electrons in the atoms combine with the protons in their ...

Many heavy elements, such as gold, are thought to form in cosmic environments rich in neutrons—think supernovae or mergers of neutron stars. In these extreme settings, atomic nuclei can rapidly capture neutrons and become ...
