Today we have become accustomed to concepts such as: time travel in various TV series and movies. The perceptions of time travel that we conjure up from these movies and TV series typically involve the following realizations: machine. For example, a time jump machine that you can step inside, a vehicle that allows you to travel through time, and a time machine that teleports you to a desired date when you press a button. Time travel is really interesting, but have we ever thought about it? possibility?
Before discussing the problems you may encounter with time travel, I would like to consider different types of time travel with some examples.
for example, terminator moviefuture john conner sends one of his soldiers (Kyle Reese) Go to the past to protect your mother (sarah conner). This soldier fell in love with his mother during his guard duty. He sleeps with Sarah Connor and gives birth to John Connor, a man from the future who is tasked by her father with protecting her mother. Noticed something strange?
This is a very simple example of a time paradox. How can a person send someone close to their own age, or even younger, back in time and have that person become their father? Also, juxtaposing the sequence of John Connor and Kyle Reese. DNA Will we understand that they are father and son in the future? Please try to imagine. A paternity test will show that you are the son of the following person. younger you and the person you are it doesn't matter. There are many movies that illustrate this paradoxical situation.
Now, forgetting about movies, let's do a little thought experiment. Go back to the past killed my father Before he met my mother. So, in this case, if I had not been born, how could I have been born, who would have to time travel in the future to kill my father? Even in this short and simple example, we witness how time travel creates paradoxes and is inherently absurd.
So what are the possible solutions? I think this paradox is possible because time travel takes place within the same universe. Recognizing the existence of parallel universes with similar timelines may open the door to time travel.
For example, consider the following scenario. kill our father In the past. When we time travel, we experience a jump from there. our own universe to another person universe. The first universe we time travel to remains empty and normal. change. In fact, a version of us in that universe would think: the machine doesn't work and perhaps Time travel will never be impossible. but, We can intervene in the events of another universe.
For example, if we kill the person we know as our father in this universe, we cannot be reborn. paradoxical existence, because our source existence It comes from Other universes (reference universes).In the first universe, our mom and dad had already met, but in this universe we didn't even know if we would be chosen among our father's millions of sperm. Therefore, we can make controlled changes to the universe and observe the results. Unfortunately, the universe in which we first time traveled will never be visited. to be influenced Due to these changes.
From this perspective, time travel seems a little more advanced Possible. because, time traveling object or person is proven by another reference universe, so no paradox arises.
The idea of time travel always excites me. I love thinking about this topic. Of course, many of the comments made on this subject are very difficult to prove, so I see no reason not to think about it and discuss it, even if it is something like a fairy tale.
PS: The series that I think best deals with this paradox:
Stein's Gate
