OpenAI Extends Single-Minus Amplitudes to Gravitons

In a fascinating intersection of AI and theoretical physics, researchers have used a large language model to tackle one of science's most complex challenges: quantum gravity. A new preprint details how GPT-5.2 Pro assisted in extending single-minus amplitudes to gravitons—the hypothetical particles that mediate the force of gravity. The AI helped derive and verify nonzero graviton tree amplitudes, a crucial step in understanding how gravity behaves at the quantum scale. This work demonstrates th
