Because it takes too long to write specific details, I plan to write a few important points.
1. Branched cosmology
Branched cosmology is the core of this movie's worldview. I don't want to bother to explain him, so I plan to copy the words in Asimov's "Edge of the Base". The part that has nothing to do with branched cosmology is removed from the excerpt.
"The universe is not unique. Many different universes may exist at the same time, but in fact they should be infinitely many. In fact, any event that happens in our universe may not happen, or it may happen in different ways. . Among the many possibilities, each may lead to a series of events in the future, so each future will be somewhat different."
"In the hazy space of chance, there are actually many other realities....in Every action and event that occurs in our reality will form many new branches, but every time the universe diverges, only one divergence will become the continuation of reality. Therefore, there should be a large number of candidates. Universe-there may be infinitely many, arising from our reality. But in theory they are all similar,..." Is
branched cosmology a scientific theory? The hero in the book says, "I believe this is a very common assumption in quantum mechanics", in other words, it is a philosophy.
But like time and space clues, going back to the past, impacting the original reality, and choosing new branches to become reality is an illusion.
2. Question
According to branched cosmology, each reality has a common origin, but once branched, it will not affect each other. After the point of divergence, what happened in Reality A has nothing to do with Reality B.
In the movie "Time and Space Clues", the agent returns to the past from reality A where he is located, hits the point of divergence, and chooses another branch to form reality B. Anything that happens in Reality B should not affect Reality A.
So, even though he saved the beauty in reality B and prevented the explosion, in reality A, the ferry exploded and the beauty died. this is correct.
But the question is, why are there traces left by many agents' actions in reality B in reality A? For example, the blood stains in the beauty's house, the ambulance in the murderer's cabin.
So many people think that this movie has huge loopholes.
3. Answer
I don't think this is a loophole. Regarding the answer to that question, the hint lies in the conversation between the agent and the experimenter before returning to the past.
The experimenter said, did you really decide to go back?
The agent replied, maybe I had made the decision long ago.
What is meant to be decided long ago. In other words, before the agent answered this sentence, an agent had already made the same decision and went back to the past, that is, reality A where the agent was at that time.
To repeat, that is to say, in addition to Reality A and Reality B, there is Reality Zero. Reality Zero, Reality A, and Reality B are all very similar universes.
The agents in Reality Zero went back to the past, hit the point of disagreement, and formed Reality A. He left clues such as ambulances and blood stains in reality A, but unfortunately, he failed to stop the murderer, so the ferry exploded, the beauty was also dead, and most of the agent was killed.
The agent in Reality A, like himself in Reality Zero, goes back to the past, impacts the point of difference, and forms Reality B. His actions in reality B are very similar to the actions of another himself in reality A, after all, the environment is the same and the personality is the same. It's just that he was lucky to stop the murderer.
In this way, "Time and Space Clues" is still very rigorous in dealing with time and space issues. The branch cosmology is more than the single branch cosmology used in "Back to the Future", "Saving the Future" or "Harry Potter" Be reasonable.
However, after resolving this huge contradiction, "Clues of Time and Space" still has some unsatisfactory features. For example, at the beginning, a piece of paper was to be passed back, and it was so serious that it was crushed into a thin piece, and everyone was arguing for a long time. When it was time to pass it back alone, the process became as simple as a B-level movie.
However, even after excluding discussions of philosophy or worldview and unsatisfactory points, the film has a good rhythm control and many highlights, and it is still a good entertainment film.
IMDB scored 6.9 (10146 people voted), I scored 6 points.
