If two protons collide at 99.9999991 percent the speed of light, do they make a sound?

It doesn’t seem like collisions of particles with no mass should be able to produce the “mass-giving” boson, the Higgs. But every other second at the LHC, they do.

Symmetry goes inside the CERN Control Center on restart day.

The bottom quark may lead physicists on a path to new discoveries.

Are these mass-giving particles hanging out with dark matter?

A hidden world of particles awaits.

In the Large Hadron Collider, protons become new particles, which become energy and light, which become data.

Grace C. Young is fascinated by fundamental questions about realms both quantum and undersea.

For the first time, experiments have seen both light and gravitational waves released by a single celestial crash.

For the first time, the Large Hadron Collider is accelerating xenon nuclei for experiments.
