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 ...
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 ...
