Time Paradox is a moment where there is a change in the past that affects the current course of time or a situation that arises from a number of premises (what is considered true as the basis for later conclusions, rationale, reasons, assumptions (sentences or propositions that are used as the basis for drawing conclusions). in logic), which is acknowledged to be true which departs from a statement and will arrive at a conflict or contradiction.
The concept of the time paradox is complex and confusing and can have very good or very bad effects.
According to Albert Einstein, there is a Cosmic Censorship where the timeline cannot be changed. If someone succeeded in creating a time machine and going back in time to change something, he would never be able to change the thing he wanted to change because of the Cosmic Censorship.
Then there is the Quantum theory which gives rise to a new theory, namely the Multi-Verse theory or what is commonly called a parallel world. This theory explains that when someone goes back in time and changes the timeline, it will cause two different "times".
Many members of the scientific community believe that time travel is most likely impossible. This belief is based primarily on the Occam razor. Any theory that allows time travel demands that all issues of causality be resolved.
In the absence of experimental evidence for the existence of time travel, it is theoretically easier to assume that this is not the case. And indeed, Stephen Hawking once said that the absence of tourists or tourists from the future visiting us is a strong argument against this phenomenon. His argument is a variation of the Fermi paradox, which opposes the existence of extraterrestrials. On the other hand, the assumption that time travel is impossible is of interest to physicists as well because it raises the question of why not and what laws of physics don't allow it.
