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

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.

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

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

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." When you purchase through links on our site, we may earn an affiliate ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

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

"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 ...
