The grandfather's paradox is one of these brain twisted time travel dilemmas, questioning everything he knows about causes and effects. The idea is that if they come back to the past and killed their grandfather before he had a child, they would never be born. But if you weren't born, why did you come back to kill him? It's like a snake eating your own cock, with a never-ending loop, with all the action contradicting in front of it.
This paradox is the focus of time travel theory - especially when I think of it linearly. If time is a straight line, dropping and changing one piece will disrupt the entire next sequence. But what happens if time is not linear? What happens if all decisions generate an alternative timeline, a new branch of a tree with infinite possibilities? Perhaps he does something else in the timeline where her grandfather lives - and they exist in only one branch, and another version of reality takes a different way.
It's not just an experiment on science fiction ideas, but is actually deeply divided into perceptions of identity, destiny and free will. When time travel can change the past, our current reality becomes vulnerable and vulnerable. However, if time is set and you cannot change the past, travel will lead to events that will always maintain your timeline. Perhaps you're going to kill your grandfather and make him fail - because the universe won't let it happen.
or maybe... they were never grandchildren. Perhaps you are part of a loop that is meant to satisfy current reality, even if your actions are always paradoxical. The more you think about your grandfather's paradox, the more you reveal not only the mistakes in the logic of time travel, but also the strange way you try to catch a human head to understand confusion with good rules.
Finally, paradoxes remind us that time can be a mystery that should not be resolved - just experienced.
