Once the most popular framework for physics beyond the Standard Model, supersymmetry is facing a reckoning—but many researchers are not giving up on it yet. The Standard Model of particle physics is ...

The Large Synoptic Survey Telescope will be named for an influential astronomer who left the field better than she found it. The Large Synoptic Survey Telescope, a flagship astronomy and astrophysics ...

Documenting the work of building the world’s largest neutrino experiment presents photographers with a unique set of challenges. Discussing her decades-spanning career, photographer Annie Leibovitz ...

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 ...

In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together ...

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 ...

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 ...

Symmetry chats with scientists working at the Large Hadron Collider to hear about differences between seven different rungs on the academic career ladder. When UC Santa Barbara professor Joe Incandela ...

Perplexed by gravity? Don’t let it get you down. Gravity: we barely ever think about it, at least until we slip on ice or stumble on the stairs. To many ancient thinkers, gravity wasn’t even a ...

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 ...

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, ...

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 ...
