The Grandfather paradox is based upon the notion of when someone goes back in time to kill his or her grandfather. Upon doing so, they are killing the person that led to the creation of them self. So, therefore, they would never be able to be born or created. Although, by never being created, they would never be able to go back in time to kill their grandfather. This leads to a never-ending loop.
Physics implications of Grandfather Paradox The physics of the grandfather paradox include the same ideas as the predestination paradox, but it would also prevent the continuation of time. In a quantum physics experiment using polarized photon pairs, physicists sent one photon of the pair into a closed time like curve simulator. When the photon emerged, it was still the same as its twin 100 percent of the time. Since the second photon acts just as the first, the grandfather must not be affected in order to maintain the same characteristics as its partner. This would show that if you change something in one item that is related to another in this way, you would also have to affect the other. This would prove that one cannot change the future or present by going to the past. …show more content…
By messing up the relationship, it would lead to him not being born. Another example is in “Doctor Who - Last of the Time Lords”. In this episode, future humans go back in time in a machine called the paradox machine. By going back in this machine, the future humans can kill their ancestors without facing the results of the Grandfather
