A community portal about The Grandfather Paradox with blogs, videos, and photos. According to Wikipedia.org: The grandfather paradox is a paradox of time travel, first conceived by the science fiction writer Rene Barjavel in his 1943 book "Le Voyageur Imprudent" . The paradox, stated in the second person, is this: Suppose you traveled back in time and killed your biological grandfather before he met your grandmother. As a result, one of your parents would never have been conceived, so you could not have traveled back in time after all. In that case, your grandfather would still be alive and you would have been conceived, allowing you to travel back in time and kill your grandfather, and so on. Thus each possibility seems to imply its own negation, a type of logical paradox.
