Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest ...

Something is out there. As far as scientists know, just 15% of the matter in the universe is the ordinary kind we can see.

As technology improves, scientists discover new ways to search for theorized dark matter particles called axions. In the early 1970s, physics had a symmetry problem. According to the Standard Model, ...

Neutrinos don’t seem to get their mass in the same way as other particles in the Standard Model. In 1998, researchers made a discovery that challenged their understanding of particle physics and ...

Project Poltergeist led to the discovery of the ghostly particle. Sixty years later, scientists are confronted with more neutrino mysteries than ever before. In 1930, Wolfgang Pauli proposed the ...

Amateur cyclotron builders are dedicated, tenacious, and obsessed. Another thing they have in common: The experience changes their lives. If the only thing amateur car builders needed was a ride to ...

The Standard Model is a kind of periodic table of the elements for particle physics. But instead of listing the chemical elements, it lists the fundamental particles that make up the atoms that make ...

The Standard Model of particles and interactions is remarkably successful for a theory everyone knows is missing big pieces. It accounts for the everyday stuff we know like protons, neutrons, ...

Our best model of particle physics explains only about 5 percent of the universe. The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and ...

Scientists around the world are testing ways to further boost the power of particle accelerators while drastically shrinking their size. At least when it comes to particle accelerators, bigger is ...

For physicists trying to harness the power of electricity, no tool was more important than the vacuum tube. This lightbulb-like device controlled the flow of electricity and could amplify signals. In ...
