As far as the worldview of sci-fi movies is concerned, generally speaking, the peculiar parts are explained, and the rest should be the same as the real world. It cannot be said that because it is a sci-fi movie, everything can be used. It cannot be said that because the Butterfly Effect is a sci-fi film, there are actually robot cats in it, and they are turned into special people with props.
As far as the butterfly effect is concerned, there are a few fixed points:
1. The time point when you travel back needs to have text, image data, or at least a strong memory.
For example, powerful landlords, what did you eat for the forty-second meal in the third grade of elementary school, can't you remember? also can't go back.
On the contrary, when was your first kiss and what was the scene, you probably remember.
So every time SAM jumps back, he wakes up from the bed, because his memory is at this point, he was fast asleep and didn't do anything.
2. There must be one and only one entity to travel back and forth.
From the movie, we can see that they jumped back and forth in the form at that time, and they did not say that there were multiple selves.
In the first part, the protagonist did not jump to the earlier stage to prevent his parents from falling in love. He could only go to the earliest data-the time point corresponding to the image of his birth.
Correspondingly, the basis for the protagonist's jump in the second part is also a photo of himself in it.
Therefore, at that time, there was already an entity, which was necessary.
As for not being able to have more than one, it is very simple. They all go back to change some similar things. If there is more than one, they will definitely meet, not to mention that the movie does not mention it at all.
Parallel cosmology is a great idea, but there's no need to speculate on this movie, it's going too far.
3. How they travel back and forth, only the objective world and their own bodies are changed, and the spirit is shared. They remember what they did and encountered in any dimension of time. This is obvious.
To sum up, here are some popular views of the great gods:
A. Little JENNY went back and set the fire. This is the most ridiculous thing.
First, she already exists why set fire to it.
Second, how did she go back in time to set fire? She wasn't even an egg at the time, and even if she had that seven or eight-year-old body, she couldn't break the fire alarm.
B.SAM put it by itself, as in the third point above.
First, he knows what he does.
Second, why did he just wake up when he went back? Very simple, he had done nothing before and was sleeping.
C. Others, fathers, professors, etc.
Fairly reasonable and impeccable, but a little farther.
Everyone feels that especially the weird smile of the little girl at the end just means that she also has the ability to jump, and maybe she has just jumped back from a certain reason in the future. After all, a classic suspense film would be too CCTV if it ends in a happy way, isn't it?
