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 ...

A very quirky quark Physicist Christian Schwanenberger has been studying the top quark since 2004. “I arrived a Fermilab nine years after the discovery,” says Schwanenberger, a scientist at DESY and ...

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 ...

Professor Anne Sickles is currently teaching a laboratory class at the University of Illinois in which her students will measure what happens when two photons meet. What they will find is that the ...

One of the great puzzles for scientists is why there is more matter than antimatter in the universe—the reason we exist. It turns out that the answer to this question is deeply connected to the ...

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 ...
