The NSF-DOE Vera C. Rubin Observatory, a major new scientific facility jointly funded by the US National Science Foundation ...

Mass is a fundamental property of matter, but there’s still a lot about it we don’t understand—especially when it comes to the strangely tiny masses of neutrinos. An idea called the seesaw mechanism ...

The Large Synoptic Survey Telescope, a flagship astronomy and astrophysics project currently under construction on a mountaintop in Chile, will be named for astronomer Vera Rubin, a key figure in the ...

At least when it comes to particle accelerators, bigger is usually better. The bigger the particle accelerator, the more energetic its particle collisions; the more energetic the collision, the ...

The Standard Model of particle physics is both fantastically successful and glaringly incomplete. Its predictions have pieced together many of the known features of the universe and guided physicists ...

In the beginning, a spaceship called the Yggdrasil is sailing through the cosmos to find a new home for its long-term inhabitants. Suddenly, the ship is hit by a stray asteroid, damaging the hydrogen ...

Nima Arkani-Hamed Professor, Institute for Advanced Study in Princeton Theoretical physicist In Particle Fever, theorist Nima Arkani-Hamed says on camera, “I’ve spent the last 15 years thinking about ...

The best of both worlds Collider experiments crash beams of particles, pumped full of energy, into one another or into a target. In the crash, all of that energy can briefly convert into new particles ...

Over the years, physicists have given names to the smallest constituents of our universe. This pantheon of particles has grown alongside progress in physics. Anointing a particle with a name is not ...

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, poring over her research. The next day, she would be giving a ...

The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and accurate in its predictions. It mathematically lays out the 17 building blocks of ...
