Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest ...

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

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 ...

NSF–DOE Vera C. Rubin Observatory is gearing up to illuminate the universe’s darkest secrets with groundbreaking new technology. Three decades ago, physicist Tony Tyson sat in the control room of the ...

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 ...

The Planck scale sets the universe’s minimum limit, beyond which the laws of physics break. In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws.

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 ...

Electromagnetism and the weak nuclear force are two distinct fundamental forces. That wasn’t always the case. How many fundamental forces are there in our universe? For particle physicists, answering ...

Scientists are championing a relatively new technique as a method to understand the structure of the early universe in three dimensions. With enough time and magnifying power, a telescope can gather ...

Just because matter is visible doesn’t mean it’s easy to see. Studies of the cosmos indicate that most of the matter that makes up the universe is dark matter—so called because it does not emit or ...

To build the DUNE neutrino experiment and its associated accelerator upgrade, experts invent customized ways to transport fragile, expensive and highly specialized components. On a late-September day, ...

Scientists in the particle physics community are bringing environmental and climate issues to the table in discussions about future research. Using a particle collider requires a lot of energy. For ...
