A proposed funding program for small- and medium-scale projects reveals insights into the science, logistical challenges, and future of particle physics research. Particle physicists have a reputation ...

The original version of this story appeared in Quanta Magazine. There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...

Buried deep below the American Midwest, a new kind of observatory is taking shape that aims to watch some of the most elusive particles in the universe as they stream straight through Earth. The Deep ...

The United States should fund proposed projects to dramatically scale up its efforts in five areas of high-energy physics, an influential panel of scientists has concluded. Topping the ranking is the ...
