Suspected violation of this floor has been folded by the system Hide this building View this building After watching it last night, to tell the truth, the film is really rotten. If we didn't insist on seeing the end, it would not be easy for people to find its purpose. After reading some comments, I feel more and more that this idea is worth discussing.
The key of the film conception is not the cycle, not the reincarnation, not the parallel universe, certainly not the quantum mechanics, but the randomness.
Before the beginning, it is necessary to retell the story of the movie: a comet crossed Mars and everything was normal. Suddenly, people found that the comet changed its orbit and hit Mars, and then people found the culprit - the "dark matter black hole" (a personal coinage, just a name), and this dark matter black hole would eventually reach the Earth and destroy everything, Blablablabla...
NASA invited two civilian scientists, who finally came up with a solution that was to launch a nuclear bomb near the dark matter black hole and detonate it to neutralize the blablablabla The point is that the "Rain Man", also known as the neurotic Teri, also came up with this idea. This is crucial for some wrong film review explanations. In one part of the film, two folk scientists explain this method to the general, while Yuren is explaining this method to his brother and sister-in-law on the other side. The two scenes are interspersed with each other, implying that Yuren and folk scientists have the same idea (to be honest, this part is the only demonstration of the director's basic narrative technique in this film --). The only difference is that, Scientists' calculation finally leads to what they think is "neutralization", while Yuren's calculation results in wormholes and time reversal.
Explain that if the nuclear bomb is launched according to the calculation results of scientists, whether the consequences will be "neutralizing" as they expected is unknown, because finally the Rain Man came to NASA and told them his calculations, resulting in a wormhole time reversal. In addition, after going back in time, Rainman told NASA about this result every time, not in some opinions. For the 673rd time, Rainman finally thought of his brother's words and wanted to communicate with others, so he told NASA about his own calculation, which was not the case.
So suppose that from the first time, the comet flew over Mars, the dark matter black hole changed the comet's orbit, the comet hit Mars, and the dark matter black hole was close to the earth. Folk scientists proposed solutions, and then at the last moment, the rain man arrived, took out the data in his computer, launched a nuclear bomb, and went back in time. The comet flew over Mars, and the dark matter black hole changed the comet's orbit, Hit Mars again... blablablabla, everything is repeated.
This was repeated for 672 times. When the 673rd time came, OMG, a miracle happened, and the comet did not hit Mars (there was performance at the end of the film, I believe everyone saw it). Everything was normal. Why? Because this time, the "dark matter black hole" did not appear, so the end of the world was impossible.
Why did the dark matter black hole not appear in the 673rd time??? Because its appearance is random!
Everything is random, which is the basis of this movie. The way Rain Man saves the earth is based on this randomness. He turned back time and time again, waiting until the dark matter black hole "randomly" did not appear. In time reversal, not only this dark matter black hole, but also other things are also appearing or not appearing randomly. For example, on the 672nd time, at the beginning of the film, the son asked his father if he could pick him up by car, and his father said no, while on the 673rd time at the end of the film, his father said yes again.
It's like the save&load method of playing games. Before killing a BOSS, file it, and then kill the BOSS, but we didn't find the equipment we wanted, so read the file, go back to kill the BOSS before killing the BOSS, and repeat this until we dropped the equipment we wanted.
