Oedipus and Antigone: is destiny determined? Is everything determined? This question has sparked lively debates and tormented both the scientific and literary world. Both fate and prophecy have appeared in literature, notably in ancient Greek and Roman plays. Two plays that stand out as being based on prophecy are Oedipus the King and Antigone, both written by Sophocles. Sophocles may have exaggerated some aspects of fate, but he had many correct observations regarding fate and destiny. I think everything is determined because free will is just an illusion, time travel depends on it, probability dictates it. In the play Julius Caesar, Cassius says to Brutus: “Men are sometimes masters of their destiny. But is it true? Can we do whatever we want or is the fate of the universe fixed? We may never know the answers to these questions. But we can guess. In Antigone, Creon is faced with a decision. Should he sentence Antigone to death or should he let her escape a crime? He feels like he has a choice between the two. But that's not the case. It was decided that he would put Antigone in a cave and try to get her out after careful consideration. No matter what he did, he couldn't resist this. He had a choice between the two, but he was determined that whatever advice he received from Haemon and Tieresius, he would inevitably choose to put her in the cave. As Oedipus described, you cannot escape fate no matter how hard you try. The prospect of time travel depends on and proves that everything is determined. If you go back and discover that you should have turned left when you turned right and you change it, you may think you have defied fate. But you are completely wrong. Most likely, like Oedipus, you will do exactly as determined and enter directly into the prophecy. Doing this will, in fact, create an alternate quantum reality in which it was intended to happen this way! (If you want to understand this, read Feynman's Sum Over Histories in any Stephen Hawking book). The prophet who spoke to Oedipus of his fate knew what was predestined. If Oedipus had moved forward in time and seen what he had done, he would have tried to avoid this fate..
