One of the first to propose this idea was physicist Richard Feynman, who, in a now-famous 1981 lecture, stated that to ...

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 force—it was just the natural tendency of objects to ...

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 ...

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 ...

Rubin Observatory will bring new capabilities to the studies of dark matter and dark energy. In just a few years, scientists at Vera C. Rubin Observatory in Chile will launch the Legacy Survey of ...

The matter-antimatter imbalance Whether neutrino masses were zero remained a mystery until 1998, when the Super-Kamiokande and SNO experiments found they do indeed have very small masses—an ...

The 2013 documentary Particle Fever follows physicists from the start-up of the LHC through the discovery of the Higgs boson. Where are those physicists now?

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 ...

Learn about the Standard Model of particle physics and how physicists use it to predict the (subatomic) future.

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe.

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 ...
