text: Hawking couldn't remember how many funerals he had attended. Due to the bio-synthetic technology powering his failing body he was now the oldest living person, despite the incurable disease that he suffered from since the 1900s. He remembered Roger Penrose funeral best, despite it being so long ago. Roger and himself had worked together on many problems in physics, but there was one issue on which they never had agreed. It was about the interpretation of quantum mechanics. Hawking smiled at the thought that Roger probably wouldn't have liked the new variant of the many-world interpretation that he was now working on. "Or, perhaps he likes it now", Hawking thought, "when it gives him eternal life". . . . . Penrose couldn't remember how many funerals he had attended. The most notable of them all was of course that of Stephen Hawkings, his dear friend and colleague, who had fought his disease for so many years. Roger had managed to stay healthy, but to his great grief he had seen his children grow old and die. Penrose had started to suspect that his friend had been right regarding the interpretation of quantum mechanics. The inner workings of physics stated that particles were in many alternative locations simultaneously, unless you tried to find out where they really were. Some physicists, among them his friend Stephen, had claimed that all alternatives really existed, and gave rise to parallel worlds. Penrose had long had a different view: "If there are multiple worlds then there should be multiple copies of Roger. In which of them, then, is my true self?" . . . . Albert couldn't remember how many funerals he had attended...
