Paradoxes limit the free will of people since they are not allowed to kill their grandparent due to the laws of causality. Causality refers to the power, by which one event causes another. It has been believed that some kind of connection is necessary between the cause and the effect of events. The study of causality has centered, in part, on trying to discover and define this connection. It is easy to see how one can make a time machine if one will consider the “twin paradox” in special relativity. If there are two people, one is in a fixed position and the other is moving at a high speed relative to the person at the fixed position. Each of the people have a watch in their hands, the person moving at a high velocity’s clock will seem to be moving relatively slower compared to the person just standing there. This occurs because of the time dilation in special relativity. We are all time travelers in one sense, or another, simply by the process of aging. We are all moving towards our future, according to decisions we make in the present and made in the past. As for today’s world time travels might be allowed theoretically, but literal time travelers are still science fiction.
