Something is out there. As far as scientists know, just 15% of the matter in the universe is the ordinary kind we can see.

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 ...

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 ...

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 ...

A professor at the University of Tennessee reimagines the way we teach STEM with a science-fiction story-based class. In the beginning, a spaceship called the Yggdrasil is sailing through the cosmos ...

Nearly 75 years after the puzzling first detection of the kaon, scientists are still looking to the particle for hints of physics beyond their current understanding. All Clifford Charles Butler and ...

Not only are we made of fundamental particles, we also produce them and are constantly bombarded by them throughout the day. Fourteen billion years ago, when the hot, dense speck that was our universe ...

Four physicists share their journeys through academia into industry and offer words of wisdom for those considering making a similar move. Throughout his higher education, Jamie Antonelli had always ...

Matter and antimatter behave differently. Scientists hope that investigating how might someday explain why we exist. One of the great puzzles for scientists is why there is more matter than antimatter ...

A team of young scientists paused their new physics searches to develop an innovative machine-learning tool, which is now helping them narrow in on a rare and messy decay of the Higgs boson. Physicist ...

Scientists on an experiment at the Large Hadron Collider see massive W particles emerging from collisions with electromagnetic fields. How can this happen? The Large Hadron Collider plays with Albert ...
