“There’s a lot of meanings for ‘small,’” says Janet Conrad, a particle physicist at the Massachusetts Institute of Technology ...

As the name suggests, particle accelerators involve accelerating subatomic particles to incredibly high speeds and smashing ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Stress is a very real factor in the structure of our universe. Not the kind of stress that students experience when taking a ...

Physicists working with the LHCb experiment at CERN have proven that a subatomic particle can switch into its antiparticle and back again. The researchers were able to prove this using extremely ...

What would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic, but it happens to shed light on our intuitions about radiation, the ...

Of all the subatomic particles that have any mass at all, the neutrino is the lightest by far. In comparison, the electron, itself a quantum featherweight, has a mass that is at least 500,000 times ...

Something unseen is influencing muons, and the findings could lead to a bigger quantum uproar than the Higgs boson did. Rae Hodge was a senior editor at CNET. She led CNET's coverage of privacy and ...

WashU physicists build quantum sensors in boron nitride sheets to study magnetism and stress under extreme pressure.

Quantum mechanics is simultaneously beautiful and frustrating. Its explanatory power is unmatched. Armed with the machinery of quantum theory, we have unlocked the secrets of atomic power, divined the ...

CERN, the world’s largest atom smasher, says it has observed three new "exotic particles" while carrying out its third run of collisions. After a three-year pause for maintenance and routine checks, ...
