Researchers have developed a method to calculate the behavior of gravitons, hypothetical particles that mediate gravitational forces, using a technique called single-minus amplitudes. This approach was previously only applicable to other types of particles, such as photons and gluons. The team used OpenAI's GPT-5.2 Pro language model to derive and verify nonzero graviton tree amplitudes in quantum gravity. This work could potentially help improve our understanding of gravitational interactions at the quantum level. --- Why it matters: This matters because it could lead to a deeper understanding of how gravity behaves at the smallest scales, which is crucial for developing more accurate models of the universe. Engineers and researchers working on AI applications related to physics may also be interested in this work as it demonstrates the potential of large language models like GPT-5.2 Pro in deriving complex mathematical results.
