All known elementary particles fall into one of two categories ... This feature prevents matter from collapsing in on itself — it’s why the electrons in every atom exist in “shells.” Without this ...

Top quarks, in particular, are already the heaviest known elementary particles—the basic particles that makes up matter—clocking in at 184 times the mass of a proton. Some quarks produced from smashed ...

In this case, the two groups of particles were iron ions and erbium ... Spin describes the angular momentum of an elementary particle or atom. It dictates the behavior in magnetic fields and ...

Spin describes the angular momentum of an elementary particle or atom. It dictates the behavior in magnetic fields and is important for determining the statistical properties of collections of ...

Buried deep in the ice in the Antarctic are "eyes" that can see elementary particles called neutrinos, and what they've ...

Swinburne researchers have discovered unexpected and entirely new quantum behaviors that only occur in one-dimensional ...

Light's interference patterns may emerge from quantum particles, not waves, challenging traditional wave-particle thinking.

Neutrinos are the only known elementary particles whose mass remains unknown, though questions remain about how well those elementary particles cooperate with the Standard Model. Determining the ...

"The claim that dust is halfway between an atom and Earth would be valid on a logarithmic scale for dust particles that are a ...

MIT scientists have snapped the first-ever images of individual atoms interacting freely in space, making visible the elusive ...
