Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

For more than two decades, researchers at Brookhaven National Laboratory’s particle accelerator have recreated conditions similar to those at the beginning of the universe. Now, the Relativistic Heavy ...

Scientists at the Large Hadron Collider (LHC) at CERN have successfully transmuted lead into gold — not by alchemy, but by smashing heavy ions together at nearly the speed of light. The process, ...

A snapshot of a computer simulation showing how energy density changes over time in the collision of a lead ion with a photon emitted by another lead ion. The world’s largest and most powerful ...
