At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

Quantum field theory (QFT) is a research area in theoretical physics that formulates fundamental interactions in terms of quantized fields defined over spacetime, unifying special relativity and ...

University of Chicago physicist Clay Córdova has been named a recipient of the 2026 New Horizons in Physics Prize for his work in quantum field theory. He was recognized alongside three colleagues: ...

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 ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...
