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 ...

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 ...

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 ...

The Standard Model is far more than elementary particles arranged in a table. The Standard Model of particle physics is often visualized as a table, similar to the periodic table of elements, and used ...

To encourage discussion and engagement, a physics forum has banned PowerPoint slides in favor of low-tech whiteboards. A physicist is more than the sum of his or her slides. That's why, about six ...

Hadrons count among their number the familiar protons and neutrons that make up our atoms, but they are much more than that. In the early 1900s, physicists were trying to find the source of a ...

A possible explanation for the lightness of neutrinos could help answer some big questions about the universe. Mass is a fundamental property of matter, but there’s still a lot about it we don’t ...

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 ...

Just over 40 years ago, a new theory about the early universe provided a way to tackle multiple cosmological conundrums at once. For Alan Guth, insight into the origins of the universe started in a ...

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...

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 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.
