The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

But only in the last 70 years have we known for certain they were there. In 1956, physicists Clyde Cowan and Frederick Reines ...

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 ...

The United States' military has announced it is seeking to create powerful subatomic particle beams that would enable personnel to "see" through walls tens of yards thick and even peer deep ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of 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, ...

China is nearing completion of an advanced facility to measure neutrinos, the smallest subatomic particles known to physicists. Its underground central sphere will soon be sealed off and filled with ...

They're tiny, invisible, and travel across the universe. And trillions of them just flew through your body. What are they? Neutrinos ‒ and scientists Wednesday announced the discovery of the most ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. One of the biggest questions in particle physics is whether the ...

Stress is a very real factor in the structure of our universe. Not the kind of stress that students experience when taking a test, but rather the physical stresses that affect everyday objects.

GENEVA — The physics lab that’s home to the world’s largest atom smasher announced on Tuesday the observation of three new “exotic particles” that could provide clues about the force that binds ...

This lesson utilizes an adaptation of the board game Subatomic: An Atom Building Game to help students learn about the different parts that make up an atom. During their turn, players can choose to ...
