Hypothetically, a group of scientists create a creature that is capable of creating a universe. In fact this being does create a universe, exactly like ours and in the place of ours, which it demolishes and throws away. This universe is so much like ours that the scientists who created the creature are duplicated there, and still attempt to control (perhaps even succeed in controlling) it in the same ways that they were before. Is either the creature or the universe now real?
