Tomorrowland The topic of Tomorrowland is quite deceptive. Halfway through the movie, I realized that the little boy did not travel to the future, but just traveled to a parallel world. Therefore, the name Tomorrowland is only derived from Disney's Tomorrowland theme park.
The time and space logic of time and space movies is very important, which is the foundation of the whole article, and everyone also has their own time and space views. My understanding of time and space travel has been basically finalized after movies such as "Time and Space Clue", "Butterfly Effect", "Time and Space Crime", and time and space travel should be said to be a kind of feedback, and its changes are complex and reasonable.
The movie doesn't actually travel through time and space, just a machine that can detect the future. The principle of the machine is on the surface that it is a superluminal particle that can detect the future. I personally think it is a kind of supercomputer that calculates the future development according to all the current conditions (although such a supercomputer may not be possible. exist). It doesn't matter, we just assume that a machine can predict the future based on the facts of the present.
Then there is a problem, when the machine detects the future and presents it to people to see, the person's thoughts change, and the future also changes, so the machine's prediction is not accurate. However, the machine in the movie obviously sees this and takes itself into account, that is, just now the machine (let's set it as machine A) calculated the future of the Earth without future probes, and now the machine (let's set it as machine A) Machine B) has detected a future of Earth with a future probe, apparently Machine A. The future has changed again. This machine keeps calculating, and this machine keeps calculating the future feedback. Finally, in a certain cycle, the balance has been reached, the feedback has reached the balance, and the future has been stabilized.
Anyone who has studied circuits knows that if a negative feedback or positive feedback is added to the circuit, the balance will be achieved almost instantaneously, so there will be no intermediate state.
Following this logic, several future detections in the movie can be explained.
(1) The future detector detects the destruction of the world, and a steady state of the future detector is to detect the future destruction, and the future is really destroyed. Occasionally a bright future can be detected, but this is not a steady state, and an occasional bright future cannot change the current general trend.
(2) Future Phantom detects that the hat is flying. This is normal, it may not have been feedback, and it will be stable once.
(3) Phantom of the future tells Casey how to start the bomb. This is obviously the result of multiple feedbacks. This is the only steady state. If it is detected that she does not move at all or uses the wrong starting method in the future, she will definitely not follow the situation at that time. Only when it is detected that she uses the correct method If the bomb is activated and the bomb responds, she will follow it, so as to achieve a steady state.
(4) The future phantom detected that Frank was killed, and the little robot saved him and changed the future. This is the only two situations in the film that change the future, the other being the main line of the film.
The system predicts the future and reaches a steady state, why does the future change over time? I think a possible explanation is that the computing power of this future detector is limited, or there are factors outside the system. The subjective initiative of humans or robots is somewhat unpredictable and can exceed the upper limit of humans. In the movie, the persistent efforts of several protagonists made a ray of light in the darkness, and the emotional system generated by the little robot cannot be calculated by any future detector. How can the machine fully calculate the human? ? Man is not just a collection of many particles, but there is also a wonderful thing hidden in it, such as a soul.
The same logic as above can also explain many time-travel movies. The moment you travel to the past, what you are about to do must match your memory, and the moment you plan to change the future, your memory will change. This is why you go back to the past to kill your grandfather, and you will fail due to various accidents. This is a steady state.
By the way, I would like to recommend the movie "Time and Space Sin", its review is an important foundation of my time and space view.
