Grandfather paradox from a new perspective

Abstract : People had considered time as an absolute phenomenon for centuries when, for the first time, Einstein in 1905 criticized the absolute essence of time by introducing “relativity.” One of the byproducts of relativity is the possibility of time traveling. Although being only theoretically possible for now, time traveling has become an attractive subject for physicists and philosophers and so has offering resolutions to avoid various paradoxes related to time travelers. One of the most famous paradoxes related to time traveling is the grandfather paradox. In this paper, a few ideas about the possibility of time traveling and avoiding related paradoxes are reviewed, and a new window is opened through which the “grandfather” paradox for a time traveler who retrogresses to the past is investigated and discussed. This perspective tries not to solve the paradox but to deny it.
