This study explores GPT-4 as a co-collaborator in scientific research, focusing on evaluating the consistency of Einstein’s Special Relativity Theory equations. GPT-4’s human-level performance makes it a valuable partner in complex research areas with limited access to human experts. Through in-depth conversations, GPT-4 confirmed an inconsistency in the SRT equations, challenging the theory’s validity. This inconsistency persisted except where x=ct, a conclusion reached after GPT-4 advised expanding the range over which the inconsistency was observed. Despite GPT-4’s biases, preference for preserving Einstein’s theory, and mathematical limitations, it contributed to an improved analytical approach and constraint expansion. This paper underscores the benefits and challenges of using GPT-4 in scientific research and highlights the need for caution regarding biases and limitations in large language models. Future research should aim to enhance these models' accuracy, trustworthiness, and objectivity in complex or controversial domains.
