In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

Physicists are quietly rewriting the rulebook for how we might cross the gulf between stars, not by bolting bigger rockets to ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

For decades, physicists taught that superconductivity and magnetism could not share the same space. One state should destroy ...

A quarter of a century ago a conjec­ture shook the world of theoretical physics. It had the aura of revelation. “At first, we had a magical statement ... almost out of nowhere,” says Mark Van ...
