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

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 ...

The ancient Greeks speculated that it might be air, fire or water. A century ago, physicists felt sure it was the atom. Today, we believe that the deepest layer of reality is populated by a diverse ...

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 ...

Knowable Magazine reports that neutrinos may help explain the universe's missing antimatter, shedding light on ...

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

As a central hub for scientific exploration, CERN, the European Organization for Nuclear Research, is dedicated to probing the enigmatic particles that could potentially elucidate the mystery of dark ...

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 ...

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, ...
