Over the past century, quantum field theory has proved to be the single most sweeping and successful physical theory ever invented. It is an umbrella term that encompasses many specific quantum field ...

In a short talk at Caltech, physicist Richard Feynman laid out a vision of manipulating and controlling atoms at the tiniest ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball rolling in ...

Physics is the study of the underlying laws and mechanisms explaining how the universe works. Most of what we do in daily life is based on a principle or law of physics—dealing with forces, motion, ...

A newly discovered mechanism known as microtube implosion could make it possible to generate magnetic fields 1000 times stronger than any yet seen in the laboratory. According to the researchers who ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

Physicists take on the big questions to discover how the universe works—from the smallest particles to the largest galaxies. Physicists experiment, observe, and analyze phenomena using mathematical ...
