How do you understand the final ending of the film Source Code? Thank you, everyone.

The key is whether the source code can change the past.

If 1 can, then the invention of the source code is beyond itself, then time will go back, and naturally it will be the end of the movie.

2 If it cannot be changed:

You can go into the past, find the murderer and lock the vehicle, but the train finally exploded and people died.

The result is that the murderer can be found, but it can't change the ending. It was also shown in the middle of the movie, and the protagonist got off the train and died inexplicably. So even if the bomb is found and dismantled, the train and people will actually die and explode inexplicably, and in these eight minutes.

So there is a contradiction here, inexplicably dead and blown up, which is untenable in theory.

Generally speaking, no matter how advanced human inventions are, it is impossible to go into the past and change history in person.

Time can never go back, so the source code is an illusion, a positive thinking about future science, and it cannot exist.

Maybe what the film wants to express is just a mental design. When there are no loopholes in the design, it is a work of art. ..

It is obvious that the film is flawed, so the author is just designing but failed.
