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 ...

European researchers say they have discovered a new subatomic particle that helps confirm our knowledge about how quarks bind — one of the basic forces in the shaping of matter. The CERN physics ...

When it comes to talent, versatility and the power to change the world, which atomic particle is the champ? Read what our four contenders have to say—then you decide. Physics fans, are you ready to ...

A pair of physicists announced the discovery of a subatomic event so powerful that the researchers wondered if it was too dangerous to make public. The explosive event? The duo showed that two tiny ...

Elementary particles are the smallest known building blocks of the universe. They are thought to have no internal structure, meaning that researchers think about them as zero-dimensional points that ...

The stuff you scrape off burnt toast is made primarily of atoms of carbon. But what makes up a carbon atom—or any other atom? The first subatomic particle to be identified was the electron, in 1898.

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Last month, Microsoft announced a new quantum computing chip called Majorana 1 that it expected would “realise quantum computers capable of solving meaningful, industrial-scale problems in years, not ...

Physicists have measured the temperature inside the hottest fireball on Earth, a four-trillion-degree jumble of melted protons and neutrons. This soup of subatomic particles, created in collisions of ...

Wolfgang Pauli, the Austrian physicist who predicted the neutrino’s existence, also won a Nobel, but not for the neutrino (he did a lot of other very important stuff). He might have won for the ...
