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

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

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 ...

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 ...

The fundamental particle of light is both ordinary and full of surprises. What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible ...

Can a theory that isn’t completely testable still be useful to physics? What determines if an idea is legitimately scientific or not? This question has been debated by philosophers and historians of ...

Amy Catanzano bridges the worlds of poetry and science. In April 2018, Amy Catanzano sat in her loaned office at the Simons Center for Geometry and Physics at Stony Brook University in New York, ...

The average banana produces a particle of antimatter roughly once every 75 minutes. US-based scientists and students working on research and experiments with the Large Hadron Collider contribute to a ...

Matter and antimatter behave differently. Scientists hope that investigating how might someday explain why we exist. One of the great puzzles for scientists is why there is more matter than antimatter ...

The Planck scale sets the universe’s minimum limit, beyond which the laws of physics break. In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws.

The answer has to do with dark matter’s role in shaping the cosmos. Half a century after Vera Rubin and Kent Ford confirmed that a form of invisible matter—now called dark matter—is required to ...
