The record of writing a short film review for the first time:
Regarding the logic of time travel, I think the "loop theory" and "causality theory" of single-line travel were created by Asimov's "The End of Eternity", and the time and space travel system involved in this drama "Darkness" The first two seasons were also carried out strictly according to Asimov's vision: this is the most direct way to solve the grandfather paradox, which essentially uses time only on human physiology, and uses human growth and aging as a distinction. time, identification of individuals. The grandfather paradox doesn't happen because your grandfather's past is your future, and you don't act in a way that affects your own world line. In other words, your behavior has been predicted by the world line, and everything you do is reasonable. , so no matter how much you try to kill your grandfather, you can't succeed in the end. Under this theoretical system, the "free will" that is so important in philosophy and theology becomes worthless. You think you have Free consciousness, but in fact your thoughts are already pre-existing (pre-existing), which is also the most criticized point of this circular theory. The third season actually proposed a new idea, that is, quantum entanglement. This theoretical system is to highlight free will, that is, the uncertainty of people will lead to the division of the world line, which is reflected in the "Darkness" series. The hesitations of the world's Jonah and the next world's Martha respectively create another world, which is explained in detail in "Rick and Morty" S02E01. In science fiction author Ted Jiang's short story "Anxiety is the Vertigo of Freedom" (included in the short story collection "Breathe"), Ted points out that another parallel world exists only if you observe it, and that it exists only when you observe it. Before this action happened, the world lines of the two worlds were consistent; note that this is only similar to the theory of the episode, and the actual operation of the two works is still different. In this episode, if the second world and the real world are not introduced, the world line cannot be linearized by the first "circular theory" alone. The reason is that the paradox of "the chicken produces the egg, and the egg produces the chicken" is infinite Recursion has no exit - all actions of all people cannot escape the predestination of the timeline. If you try to forcibly break this cycle, the events after the cycle start will not exist (this is also what Asimov did not do back then, He did not actually provide a breaking idea for this one-line cycle) - one thing existed in the future, but it did not exist in the future, it sounds very quantum mechanical, so it is natural to have this parallel world as a merger The setting of the timeline and the world line provides an exit for all players in the world to break the game; this is also what I think is the most amazing part of this show-it is technically impeccable,
