Particles and fields

Finding these particles would confirm there are laws of nature beyond the Standard Model of physics, say the researchers.

A new paper hypothesizes how the amount of dark matter could have grown exponentially in the early universe.

Scientists need to pin down the lifetime to better understand fundamental physics questions, like how the universe evolved.

Noisy measurements of gravitational waves may illuminate what links gravity to other fundamental forces.

A recent experiment has created a one-way quantum network between two labs, reaching a milestone on the path to creating a quantum internet.

Scientists may soon be able to observe a dramatic, long-predicted consequence of Einstein’s theory of general relativity.

Particle physicists have overcome one of the biggest obstacles to a collider that would smash particles for less.

A next-generation atom smasher would cost billions of dollars. Europe and China both plan to build one, but scientists are debating if it's worth it.

Other researchers dispute whether astronauts would experience the type of radiation used in the experiment.

A new paper proposes two experiments to test if the steadiest components in physics are really kind of shifty after all.

For the first time, researchers have shown that antimatter interferes as a quantum wave in the same way regular matter does.

New findings suggest that ordinary sound has negative gravitational mass.
