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 the potential of advanced AI as a collaborative tool for fundamental research, capable of navigating intricate mathematical derivations in quantum field theory that would be exceptionally time-consuming for humans alone. While not replacing physicists, the model acts as a powerful accelerator, checking calculations and suggesting novel approaches to age-old problems in our quest for a unified theory of physics.
