China wants to build a next-generation particle collider that would be cheaper and more powerful than Europe’s planned successor to the Large Hadron Collider

Molecular Bose-Einstein condensates could help to provide the answers to fundamental questions or form the basis of new quantum computers

Cosmic Microwave Background Stage 4, a top-priority project for U.S. astrophysics, was designed to make breakthrough observations of the universe’s very earliest moments. Now the U.S. government says it can’t currently support the project’s construction at the South Pole

Every now and then, tiny particles of antimatter strike Earth from cosmic parts unknown. A new balloon-borne experiment launching this spring may at last find their source

Domain walls, long a divisive topic in physics, may be ideal explanations for some bizarre cosmic quirks

New discoveries demystify the bizarre force that binds atomic nuclei together

The Nobel Prize-winning theorist’s prediction of the Higgs boson sparked a half-century quest of discovery that reshaped physics—and our understanding of the universe

A new generation of lab experiments is aiming to weigh neutrinos with astonishing accuracy

Several branches of modern physics, including quantum theory and cosmology, suggest our universe may be just one of many

Electron tornadoes that mimic “magnetic monopoles” emerge from specks of rust
