What is grandfather paradox?

Grandfather Paradox

The grandfather paradox is a proposed paradox of time travel first described (in this exact form) by the science fiction writer René Barjavel in his 1943 book Le Voyageur Imprudent (Future Times Three). The paradox is described as following: the time traveller went back in time to the time when his or her grandfather had not married yet. At that time, the time traveller kills his or her grandfather, and therefore, the time traveller is never born when he or she was meant to be.
