# ExplorationBench: Measuring AI Systems' Exploration in Verifiable Alien Worlds > Source: > Published: 2026-09-25 03:00:02+00:00 Scientific discovery begins where known problems end. There, AI systems must engage in exploration: framing hypotheses, designing experiments, and iterating on the results. However, evaluating this ability is difficult: (1) how to verify whether a genuinely new hypothesis holds, and (2) how to deter
