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 ...

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 ...

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 ...

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 ...

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 ...

For more than two decades, amateur photographer Dale Carter has documented the physicists who come to the Black Hills for their research. Photography is sometimes thought of as one part skill and one ...

Physics may seem like its own world, but different sectors using machine learning are all part of the same universe. In 2017, Savannah Thais attended the NeurIPS machine-learning conference in Long ...

Every six months on the spring and autumn equinoxes, a serpent slithers down the side of the El Castillo pyramid in Chichén Itzá, Mexico. Well, it’s not a real serpent—it’s an optical illusion caused ...

Building the Large Synoptic Survey Telescope also means solving extraordinary technological challenges. In a brightly lit clean room at the US Department of Energy’s SLAC National Accelerator ...

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 ...

Brazilian physicist César Lattes, considered a national hero for his discoveries, paved the way for trailblazing research projects in particle astrophysics across Latin America and beyond. When César ...

The CMS experiment is developing a new type of trigger that looks for anomalies. As far back as he can remember, Abhijith Gandrakota has felt a natural pull toward physics. “For me, it’s a fundamental ...
