But what would happen if you accidentally crashed your time machine on a teenage version of your Grandfather? Time Travel Simulation Resolves “Grandfather Paradox” What would happen to you if you went back in time and killed your grandfather?

Some will understand this, perhaps just the feeling of the need to share. A paradox implies that it would be illogical for any possible outcome of this event … This is the Grandfather Paradox.

If time travel was logically possible then the time traveller could return to the past and in a suicidal rage destroy his time machine before it was completed and murder his younger self.

A paradox, in time travel, is "a situation in which the effect of an incident contradicts or eliminates the cause of that same incident". A man goes back in time and kills his mother back before she had ever gave birth to him in that time frame.

This does not happen. This time travel model would make your grandfather virtually death proof. You can pull the trigger, but the laser will malfunction. Simply put, the answer is this: In the fictional Universe of the Back to the Future movies, creating a certain kind of time paradox can lead to the destruction of the Universe. The TERMINATOR Paradox is about the TERMINATOR, not about John Connor, hence the name. Others think we have to find a new way of thinking about *causality*, the idea of cause and effect. Since Joe 3 has not traveled back in time, he never was able to escape a potential Joe 4 which leads to the infinity loop. Some might think this doesn't belong here... each to their own but I would appreciate thoughts and feedback. The man realizes that the stranger was himself, using the time machine to travel back and give the plans to his younger self. If it did exist, it would occur, and there's be no way to keep it under wraps. Very well, time paradoxes would create repeating loops in a single time-line universe essentially stopping it from going forward and create divergent paths in multiverses.

Some people think this means that time travel is impossible. This is why they are called a “paradox”.

(Math and physics are supposed to reflect reality, not dictate it. But then you wouldn’t be around to interfere … I think it's just because it would cause a change of events that should off never occurred. The classic example of this is the "Grandfather paradox". Perhaps a bird will poop at just the right moment, but some quantum fluctuation will occur to prevent a paradoxical situation from taking place. The original paradox is too, a grandfather paradox: What would happen if I went back in time and killed my own grandfather? An example of this would be in which a person travels back in time and kills his/her grandfather before the latter met the traveler's grandmother.

A lesson we're straying farther and farther from.) It's never occurred.
