Grandfather Paradox
(JKB)
The grandfather paradox is a very simple,
science-fiction-based apparent inconsistency at the very heart of the idea of
time travel into the past. It''s very simply that you travel into the past and
murder your own grandfather before he sires your mother or your father, and
where does that then leave you? Do you instantly pop out of existence because
you were never made? Or are you in a new causality scheme in which, since you
are there you are there, and the events in the future leading to your adult
life are now very different? The heart of the paradox is the apparent existence
of you, the murderer of your own grandfather, when the very act of you
murdering your own grandfather eliminates the possibility of you ever coming
into existence.
Among the claimed solutions are that you can''t murder your grandfather. You
shoot him, but at the critical moment he bends over to tie his shoelace, or the
gun jams, or somehow nature contrives to prevent the act that interrupts the
causality scheme leading to your own existence.
