Analysis experts are here to answer questions about the movie "Source Code": How did Goodwin in the parallel world at the end of the movie know the name of the criminal?

① In fact, every time goodwin uses the source code to let the male protagonist go back, he creates a new world (that is, the source code world), rather than letting the male protagonist go back to the past to find the person who planted the bomb.

②The real world and the new world do not interfere with each other. At the beginning of the film, the train has exploded in the real world and all the people are dead and cannot be resurrected. Then the new world created at the end of the film goodwin felt very excited when he saw the text message. Surprise means that reality and the new world are not connected. The two goodwins have different memories in different worlds.

③The male protagonist finally survives in the new world, but his identity is to survive as a history teacher, so if he goes back to find his dad in the new world, what his dad will see is History teacher, go find goodwin. What goodwin sees is also the history teacher, and there is no memory of returning to the train to do experiments countless times before in goodwin’s memory, because she is not from the real world, but from the new world, that is me. The two goodwins in different worlds mentioned above have different memories.

④The text message was received by Goodwin in the new world. You can tell from her expression.

⑤ Hypothesis 1: If the male protagonist did not prevent the explosion in the end and goodwin did not end his life, it would be an infinite loop like the beginning of the film. After the male protagonist was bombed, he would return to the new world with his remaining brain waves. The mission continues in the real world. .

Hypothesis 2: If the male protagonist prevented the explosion, goodwin did not end his life. I still remember the previous experiment in which the male protagonist took his girlfriend off the train and found the man with a cold. He thought he was the bomber, but no, the train exploded. The male protagonist could survive in the new world because he was not bombed. But because goodwin didn't end, I couldn't escape my fate for 8 minutes. I was hit by another train and returned to reality. If goodwin stops living at that time, the ending will be like hypothesis 4. The male protagonist will live with his girlfriend in the new world, but the other people on the train will be blown up in the new world. And if the bomber is not found, Chicago is in danger! !

Hypothesis 3: If the male protagonist fails to prevent the explosion in the end, goodwin ends his life, the male protagonist’s new world is blown up, and goodwin also stops his brain waves in the real world, so the male protagonist cannot go to the new world. It can't go back to the real world, it will really never exist.

Assumption 4: If the male protagonist prevents the explosion and goodwin ends his life, that is, everyone on the train in the new world is not dead in the ending. The male protagonist finds the bombardier, so there is no such thing as doing anything in the new world. The experiment was looking for a bombardier, so that’s why the doctor was so angry. His gas source code was not used. Goodwin was so surprised when he saw the text message because they were both another doctor in the new world and Goodwin didn’t go back to the past! ! But the new world created by the source code! !
