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

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 ...

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 ...

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 ...

Because they supposedly formed about 14 billion years ago, some primordial black holes are thought to be on the verge of ...

An international team including scientists from Princeton University has detected subatomic particles deep within the Earth's interior. The discovery could help geologists understand how reactions ...

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 ...

Scientists have proposed a new kind of subatomic particle to explain another particle’s mysterious disintegration. What just ...

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 ...

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, ...
