Time Travel Fiction to save JFK


Much Fiction has been written, but can we go back and change a big event? The movie Valkyrie is about a plot to get rid of Hitler and many people wonder if you could go back in time and do it. I prefer a more positive approach to prevent an event, as in saving JFK in Dallas. However, could you time travel back to save JFK from Lee Harvey Oswald and change history?

According to Steven Gibbs, if you go back to the past and make a change you split the timeline into two. This is to prevent the Grandfather Paradox.

The Grandfather Paradox is a theory that time travel is impossible because if it were you could go back and off your grandfather, and then how were you ever born? The problem is that it reminds me of a teacher that said insects could only grow to be a few inches long because they have no lungs and air takes too long to diffuse in. Well, big bugs are in the fossil record the biggest was nine feet long. A theory may make sense, but reality operates on its own scale.

The timeline splits so you now have timelines A & B. At the point of divergence you have a change on A - the original line JFK dies, and on B - the new line JFK lives. Needless to say B starts getting more and more strange as time goes by.
